Fanelli Equipment Repair Upgrades to VMAC DTM70-H

Located in Hilmar, CA is Fanelli Equipment Repair. Owned by Phil Fanelli, this company has been operating in the Central Valley area for over 12 years, repairing and servicing all types of Caterpillar equipment, including landfill, recycling, and compost equipment for waste management companies, as well as servicing equipment used in the dairy industry.

Phil Fanelli has successfully grown his equipment repair business to include seven service trucks, each which puts on thousands of operating hours and up to 50,000 miles every year. “I work my trucks hard, and so I rotate through them every five years, to ensure there’s no downtime,” says Fanelli. “Because of this, I expect any piece of equipment to last me five years as well.”

Up until recently, Phil’s service truck was equipped with a reciprocating air compressor. This reciprocating air compressor resulted in a lot of challenges, the first and foremost being weight. The compressor was terribly heavy on his truck, which at the time was a Peterbilt with a 14-foot service body. Phil also found himself waiting for compressed air to be produced, resulting in downtime as his compressor tried to catch up to him. This slowed down his work.

When it was time to bring in a new service truck to the fleet, Phil seized the opportunity to “right-size” his truck. Because he’s often travelling to visit his technicians on different job sites, he chose to downsize to a Ford F550 truck. He also needed to address the weight and air supply concerns associated with reciprocating compressors. For this truck build and upfit, he went straight to Spencer Hinson, owner and GM of Lodi Truck and Equipment, located in West Sacramento.

“I’ve been getting Spencer at Lodi to build my trucks for over 10 years now, and I wouldn’t go anywhere else,” says Phil. “I go in, tell him what I want, and he keeps me involved in every step of the build.”

At first, Phil was interested in an UNDERHOOD™ 70 air compressor, which fits neatly in the engine compartment of the truck, supplies up to 70 CFM of air continuously, and weighs just 150 lbs, saving up to 260 lbs. But when it was time to start the truck build, Spencer recommended a different product: the newly released VMAC DTM70-H, a direct-transmission mounted PTO driven air compressor with hydraulic pump. The DTM70-H is the best choice for customers like Phil who are concerned with saving weight on their service truck, and who also need compressed air and hydraulic power at the same time.

“Spencer knows I’m really concerned about weight. It seems like I’m always overloaded, and he thought this set up would be the best fit,” explains Fanelli. And the weight savings were significant: “The VMAC DTM70-H saved 500 lbs, which is a big deal when you’re trying to set up an F550. With these weight savings, it was the only way to go. We were looking at aluminum doors and aluminum fuel tanks, but to save 500 lbs with one change tFinelli-VMACo the DTM70-H was a no-brainer.”

The VMAC DTM70-H weighs only 180 lbs, which frees up hundreds of pounds of weight, and allows customers like Phil to downsize their trucks, and at the same time load the truck up with more supplies. “I added more tools, a drawer set, tool boxes, and an oil tank, thanks to the weight savings,” says Fanelli.

It’s been several months since Phil picked up his new F550 truck from Lodi, and he’s been using the DTM70-H to power his air tools and crane simultaneously. Spencer’s expertise and recommendation was key in this new truck build and was exactly what Phil needed. “When I got the truck, it was show room quality, detailed, everything worked. It was exactly the way I wanted it.” And as for the DTM70-H? “It’s lightweight, which is what I needed, but it also produces the air I need, when I need it. It’s bulletproof.”

CHRIS MOYSE, MECHANICAL ENGINEER

VMAC has recently launched the DTM70-H direct-transmission mounted PTO driven multi-power system. This innovative VMAC system is notable as allows for simultaneous operation of the air compressor and hydraulic pump. In this segment of Meet the Team, we sat down with Chris Moyse, one of the Mechanical Engineers who developed the DTM70-H, to learn more about his role and experience at VMAC, and what he enjoys doing when he is off the clock.

CAN YOU DESCRIBE YOUR ROLE AT VMAC?
I’m a Mechanical Engineer on the Vehicle Integrated Products Team. As part of this team, I work on integrating VMAC products, including the UNDERHOOD, DTM70 and DTM70-H, into specific vehicles. This includes design, development, testing, and supporting these systems.

HOW LONG HAVE YOU WORKED AT VMAC?
Almost two years.

WHAT DO YOU LIKE MOST ABOUT YOUR JOB?
I like to see one of my ideas transition from concept to drawing, from drawing to physical part, and then to a working compressor. I like seeing my ideas come to life.

I also like being so closely involved with the people who make our products. Having our manufacturing facility just steps away from the office allows for good dialogue with all departments, including machining and assembly.

HAVE YOU HAD ANY PARTICULARLY INTERESTING OPPORTUNITIES WHILE WORKING AT VMAC?
I’ve had the opportunity to travel and work with our VMAC Dealers to do customer installs. It’s great to be able to travel to new places, meet our dealers, and help do a new product install, taking care of any fixes we need on the fly. A couple of months ago I was able to travel to California with another member of the Engineering team to do the first VMAC DTM70-H install at Lodi Truck and Equipment for a heavy equipment repair customer.

ANY MEMORABLE MOMENTS YOU’D LIKE TO SHARE FROM DEVELOPING THE DTM70-H?
When we were in California at Lodi and we got the first unit running, it was great to see the reaction of the installer when the DTM70-H first fired up. The dealer was thrilled to see it working and couldn’t believe how quiet it was compared to a reciprocating air compressor. They played around with running the air compressor and the crane at the same time (all from their wireless crane remote). That was a fun day.

WHY DID YOU CHOOSE TO WORK AT VMAC?
I was hired as a co-op student at VMAC several years ago, and once I finished my schooling I was really motivated to come back because so much is done in-house. You get to be involved in every stage of development and can get the whole depth of the manufacturing process. VMAC also has a friendly and positive atmosphere.

WHAT ACCOMPLISHMENTS ARE YOU MOST PROUD OF DURING YOUR CAREER HERE?
During the development of the DTM70-H we’ve been able to achieve many manufacturing improvements. The engineering team has collaborated closely with the machinists in the VMAC Custom Shop, the Foundry, and VMAC’s Quality Department to solve technical challenges. We hope these improvements will make things easier for our production team and save time in the manufacturing process. Working closely with these teams has been really rewarding.

WHY DID YOU CHOOSE TO BE IN MECHANICAL ENGINEERING?
I wanted the ability to see the ideas in my head become reality, and that guided me to engineering.

WHAT DO YOU LIKE TO DO ON YOUR OFF-TIME?
I enjoy restoring classic cars and woodworking. My family has always been involved with old cars, and I have been involved with the hobby from a very young age. Since I started working, I have had the chance to combine these two passions. Over the last two years I have built an awesome workshop for restoring cars, invested in some great tools and have been learning new skills all the time. It’s safe to say that most of my paycheques will end up in my garage in one form or another!

Reduce Truck GVW By Up To 600 lbs With VMAC’s PTO Driven Air Compressor & Hydraulic Pump

When spec’ing out equipment for a medium duty Class 5 truck with a max GVWR of 19,500 lbs, like a Ford F550, every pound counts. Truck upfitters are supplied with a list of required equipment from a customer, and it can be tough to accommodate everything when under tight weight restrictions. Preferring not to upsize to the next weight class, upfitters and customers are always looking to get creative with Lightweighting and save as much weight as possible, while retaining functionality on their service trucks.

VMAC DTM70-H PTO Driven Air Compressor & Hydraulics Saves Weight

VMAC’s Direct-Transmission Mounted PTO Driven Air Compressor & Hydraulics (DTM70-H) weighs only 180 lbs and combines two systems, allowing customers to run both the air compressor and the hydraulic pump at the same time. Combining these two types of power into one innovative multi-power system not only saves space, but also reduces weight on service trucks to save up to 600 lbs. This PTO driven system saves hundreds of pounds of weight as it requires no air storage tank to mount on the truck deck and requires a 50% smaller hydraulic tank size compared to other hydraulic systems.

What would you do with up to 600 lbs of weight reduction on your service truck? Some ideas include:

  • Carry more materials or equipment
  • Take advantage of better fuel economy
  • Install taller tool cabinets
  • Downsize your service truck classification

More on the DTM70-H PTO Driven Multi-Power System

The DTM70-H is a direct-transmission mounted multi-power system that is designed for the F250-550 Super Duty 6.7L Power Stroke Diesel. As described above, these light and medium duty trucks benefit from lightweighting initiatives, which can help provide more options for customers.

While lightweighting is becoming an increasingly important consideration, the performance of the equipment used cannot be compromised. Here are some fast stats on the DTM70-H:

  • Up to 70 CFM @ 175 psi*
    • A VMAC North-American made rotary screw air compressor produces up to 70 CFM at 100% duty cycle. This provides enough CFM for air tools such as 1” impact wrenches, 60 lb jackhammers/pavement breakers, backfill tampers, OTR tire inflation, and more.
  • Up to 14.9 GPM @ 3,265 psi*
    • The DTM70-H control system integrates with standard crane controls for easy and simultaneous operations with the air compressor.

*Dependent on pump size and engine RPM.

(l-r)  Jim Raymond (Sales Manager), Darren Darnley (National Sales Rep), Gordon Duval (VP Marketing & Sales)

When we announced our brand promise to be the leader in mobile compressed air innovation at NTEA’s The Work Truck Show 2018 (WTS18), we promised to continue to design and manufacture innovative products to meet the needs of the work truck industry. We backed this up with examples from the last 20 years and shared two important new innovations.

The first is the new VMAC DTM70-H, a direct-transmission mounted 70 CFM air compressor with hydraulic pump, which provides simultaneous operation of the air compressor and hydraulic pump. The DTM70-H is easy to install, with no drive shafts or transfer case modifications involved, making it a true industry innovation.

The second is the new UNDERHOOD™ 40 air compressor system. It is the only air compressor specifically designed for commercial vans, providing up to 40 CFM, reducing GVW, and freeing up cargo space. Compared to its predecessor, the new UNDERHOOD™ 40 provides 33% more air power, while running the vehicle’s engine at a lower RPM.

With these new product innovations, VMAC lives its brand promise of “Air Innovated”. Validating this claim, we’re pleased to announce VMAC won Finning-CAT’s 2017 Innovative Solutions Supplier of the Year award.

(l-r) Neal Clozza (Mechanical Engineer), Michael Hildebrand (Manufacturing Engineer)

Finning is the world’s largest Caterpillar dealer, with operations in Canada, Europe, and South America. Finning has over 80 years of experience as a Caterpillar dealer, and VMAC has been the supplier of UNDERHOOD™ air compressors used on Finning’s service trucks for over seventeen years, and more recently VMAC began supplying its Multifunction Power Systems to Finning.

The VMAC Multifunction Oilman Series Power System combines an air compressor, generator, welder, battery booster/charger, hydraulic pump, and a Positive Air Shutoff System (PASS), all in one complete package powered by a small diesel engine. And this year, at WTS18, we announced the new CAT-powered version of the VMAC Multifunction.

We’d like to thank Finning for this award, which recognizes VMAC for our pursuit of excellence and innovation, supporting our Air Innovated promise.

Why Is My Compressor Shutting Off? Temperature Sensors and Switches

Temperature Sensors and Switches

Temperature switches and sensors are used on applications which require a solution to a temperature control situation. Often less complicated than most electronic controls, temperature sensors and switches are relatively easy to set up.

Temperature sensors are often used for monitoring compressor coolant, oil and air inlet temperatures as well as discharge air temperatures and logging the variations.

Temperature switches are slightly more complex, and include a sensor plus the ability to send signals. A temperature switch senses temperature levels. When the temperature passes a set point the switch sends a signal to a controller to do something to the application, like cut the power, sound an alarm, turn on a light, or disengage the clutch.

Some immersion temperature switches are appropriate for applications that require an inexpensive solution to simple temperature control. These types of switches activate with a specific rise in temperature and are available with a wide range of temperature pre-set values as well as a set point range, set point tolerance, maximum temperature cut-out setting, and probe length.

On-off controllers

An on-off controller is the simplest form of temperature control device. The output from this type of device is either fully on or off, with no middle state. An on-off controller will cut power or disengage the clutch when the temperature passes the set-point. On-off control is usually used where a precise temperature control is not necessary.

A limit controller is an on-off controller used for alarm indication. This type of controller uses a latching relay, which must be manually reset, and is used to shut down a process when a certain temperature is reached.

VMAC temperature sensors, switches, and controls

VMAC air compressors are equipped with a switch which includes an oil temperature sensor. If the compressor oil gets too hot, the switch sends a signal to the on-off controller to disengage the air compressor’s clutch. This shuts down the system and prevents high temperature related damage.

Why is my compressor shutting off?

If your compressor trips on over temperature, it could be for any of the following reasons:

  • Ambient temperature too high or not enough ventilation
  • Too low oil level
  • Wrong type of oil being used
  • Dirty oil cooler
  • Thermostatic valve not working
  • Dirt / obstruction in oil lines
  • Plugged oil filter
  • Restricted air flow over the air to liquid cooler
  • Too high an engine liquid coolant supply temperature in a liquid to liquid cooler
  • Faulty temperature switch

Excessive oil temperatures can cause damage to your air compressor including premature lubricant degradation, high oil and moisture carryover, and varnishing of the compressor internals and system components (such as the oil filter, cooler, and separator filter). Lubricant flash points also present a fire hazard.

The costs related to rectifying these issues through the use of temperature switches and controls can result in significant cost-savings, as risks of down-time and injury are minimized.

Air Tool Maintenance and Operation

The biggest concern in the operation and life expectancy of your professional-grade pneumatic tools is moisture! Specifically, water vapor. You know this water vapor as humidity, and it is always present in the air around us in varying degrees. When this air is compressed, moisture in the inlet air concentrates with each cubic foot drawn in.  As you compress air it gets very hot and because the air is very hot, the accumulated water in it remains as a vapor, however, when compressed air is expanded through air tools it cools rapidly. With high moisture content in the compressed air, this rapid cooling has been known to cause freeze-ups at the exhaust ports of pneumatic tools. Even before this hot, moist compressed air reaches the air tool, it starts to cool down just after it leaves the compressor. It then starts to condense this moisture into water.

Does An UNDERHOOD™ or Direct-Transmission Mounted Air Compressor Void My Vehicle Warranty?

For those looking for a one-word answer, it’s no. UNDERHOOD™ and Direct-Transmission Mounted air compressors do not void a vehicle manufacturer’s limited warranty on new trucks or vans.

Both Canada and the United States have laws that protect consumers’ warranties when using aftermarket parts and ensure manufacturers are staying true to their warranties. Air compressors that use PTO or engine-driven systems are considered aftermarket parts and, therefore, are covered by these laws.

Warranty Protection in the United States

The Magnuson-Moss Warranty Act is a federal law that was created in 1975 to protect consumers from companies that may not want to follow through with their warranty. The law embodies the attitude that you don’t need to have a warranty but, if you do, then you’d better make good on it.

Under the Magnuson-Moss Warranty Act, the burden of proof is on the manufacturer’s dealer to show that the aftermarket equipment caused the need for repairs before denying warranty coverage. In the context of UNDERHOOD™ air compressors, a truck manufacturer like Ford or Chrysler would have to prove that the air compressor itself caused the vehicle or part to fail.

Here is what the Federal Trade Commission (FTC) says about aftermarket parts in their Magnuson-Moss Warranty Act explainer:

“An ‘aftermarket’ part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. Simply using an aftermarket part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part.”

Even in a worst-case scenario, if an UNDERHOOD™ system caused damage to a part, the vehicle manufacturer would only be allowed to deny coverage for the part specifically damaged. The remaining vehicle warranty would remain fully intact, which is also explained by the FTC:

“If it turns out that the aftermarket part was itself defective or wasn’t installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket equipment caused the need for repairs before denying warranty coverage.”

VMAC Direct-Transmission™ Mounted and UNDERHOOD™ air compressors are built for specific trucks and applications, and that’s deliberate. VMAC engineers work with vehicle manufacturers before the release of their new trucks and vans to determine the optimal mounting locations of compressor components on any given vehicle. If VMAC can’t find a reliable way to install an UNDERHOOD™ or Direct-Transmission™ Mounted air compressor that protects you and your warranty, they don’t offer the air compressor for that vehicle. It’s that simple.

Warranty Protection in Canada

It’s a common misconception that Canada has a blanket consumer protection law that’s similar to the Magnuson-Moss Warranty Act, but that doesn’t mean consumers have been hung out to dry. Individual provinces have created their own laws to help protect consumers and ensure warranties are enforced.

In addition, major manufacturers all have Canadian warranties that are similar to their U.S. counterparts. Manufacturers know that consumers are purchasing their trucks and modifying them into service vehicles and they wouldn’t risk losing clientele over unreasonable warranty restrictions.

Instead, manufacturers’ warranties essentially follow the U.S. laws: aftermarket damage to a part may void the warranty on that specific part, but it doesn’t void the whole warranty. Here are a few examples of this in writing, straight from the manufacturers:

“What is Not Covered Under this New Truck Limited Warranty?
Damage Caused by Accident, Misuse or Alteration

  • Non-Ford parts installed after the vehicle leaves Ford of Canada’s control and causes a Ford part to fail.


NOTE: Warranty coverage will be invalidated on parts affected by such damage.”

“The warranties in this booklet do not cover repairs required because of non-FCA [Fiat Chrysler Automobiles] modifications, installation of special equipment or accessories, or use of special materials, fuels or additives. This includes special bodies, body conversions, fuel system conversions, trailer hitches, window tints, sunroofs, theft alarms, etc. Non-FCA modifications do not by themselves void your warranty, but they are not covered by your warranty”

Each province and territory has consumer protection laws that ensure manufacturers are following these warranties and staying true to their word. Manufacturers who provide a warranty are essentially guaranteeing the products and services that are included, and they do so voluntarily. Warranties are not required! Therefore, a warranty is a written guarantee that obligates the manufacturer to follow through, even if you’ve installed an UNDERHOOD™ or Direct-Transmission Mounted air compressor.

How Many CFM Do I Need To Run Air Tools? – CFM Chart

pneumatic-toolsIt can be tough to know how many CFM you need in an air compressor to operate your air tools. Too little CFM and you won’t be able to run your tools continuously—or at all!—and too much CFM could mean you’ve overspent on your air compressor.

To help you find the compressor that’s right for you, we’ve developed this helpful air tool consumption chart. But before we get into the CFM consumption chart, let’s talk a little bit about why CFM matters to you…

Jump To The Air Tool Chart

Pneumatic Tool CFM Requirements

Every pneumatic tool is rated for CFM, or “Cubic Feet Per Minute”, and the same goes for air compressors. CFM represents the volume of air that is produced by your air compressor or required by your air tool.

Your tools’ CFM requirements give you an idea of what you need your air compressor to do, but it’s not enough to simply match the air tool’s rating and the compressor’s rating 1:1. In this article, we’re going to help you better understand how many CFM you need to run your air tools.

Continuous vs. Intermittent Use

Air tools need a CFM that matches the manufacturer’s guidelines, but what air tool you have and how you use them matters. For example, if you’re using an impact wrench, are you:

  1. continuously holding the trigger down while you work, or
  2. are you using it in quick bursts with short breaks in between use, allowing the air compressor to catch up?

Do you use tools for lengthy periods of time? Or are all of your tools only used for a few seconds here and there? These are the types of questions you need to ask yourself when you start to determine your CFM needs.

If your application requires you to run air tools for an extended length of time, an air compressor with a 100% duty cycle is recommended so you can operate your tools continuously.

By contrast, tools only used intermittently may be able to get away with a less powerful air compressor that uses an air receiver tank, which may save you money.

Multiple Tools

Another common scenario that impacts CFM requirements is using multiple tools at once. Running more than one tool at a time can be a highly efficient way to get things done, especially when you have two or more people working on a single job. However, if you’re running multiple tools at the same time, you’ll need to combine the CFM requirements of each of the tools that will be running to determine your total CFM requirement.

For example, let’s say your team uses the same air compressor to power a ½” drill that requires 30 CFM, and a grinder that requires 60 CFM. If you use these tools at the same, you would add 30 CFM + 60 CFM for a total demand of 90 CFM. When choosing equipment, you would likely need an air compressor that can reliably produce 90 CFM of air.

 

6-gall-tankAir Receiver Tanks

Air receiver tanks are another factor you should consider when determining your CFM needs. Many air compressors require an air receiver tank—in fact, this is always the case with reciprocating air compressors. “Recips” need an air receiver tank and can only run at 100% duty cycle until the receiver tank runs out of stored air (or the compressor overheats from working too hard – but that’s another story…)

In some scenarios, air receiver tanks can help a lower CFM air compressor keep up with a higher CFM demand, and can be a good strategy when you don’t want to invest in a higher CFM air compressor. These air receiver tanks can vary in size from 5 gallons to over 100 gallons.

Air Tool Consumption Chart

Still wondering what this means for you? We’ve put together a handy air tool consumption chart to help give you an idea of how many CFM you need to run your air tools. We’ve also included 6 tips for choosing an air compressor, the average CFM at load (100% duty cycle), the suggested air compressor CFM, and our recommended rotary screw air compressor based on your CFM needs.

VMAC’s Rotary Screw Advantage

Depending on the product, VMAC air compressors deliver anywhere from 30 to 140 CFM at 100% duty cycle, which means you’ll never have to wait for air. VMAC air compressors also don’t require a bulky air receiver tank, thanks to the rotary screw technology, which allows them to operate at max efficiency 100% of the time. Not only are VMAC air compressors lighter and smaller, you’ll get jobs done faster, improve productivity, and be more profitable.

THIS IS THE STORY OF VMAC—AIR INNOVATED®

VMAC Machine Shop

VMAC machine shop, circa 2001

The story of modern day VMAC starts in 1997, when VMAC released the innovative UNDERHOOD™ 70 Air Compressor. This was the first time a rotary screw air compressor was mounted in the engine compartment of a truck. This state-of-the-art air compressor was a game changer, billed as “half the size and twice the output” of competing products. From then on, VMAC became known as the manufacturer of UNDERHOOD™ air compressors.

Jumping ahead to 2002, VMAC pushed the boundaries again, releasing the innovative and powerful UNDERHOOD™ 150 Air Compressor. VMAC was the first to design and manufacture a rotary screw air compressor that mounted in the engine compartment and was capable of producing up to 150 CFM.

Then in 2004 VMAC became the true in-house manufacturer that it is today, when it began manufacturing its own proprietary rotors for its screw compressors. To this day, VMAC is still one of the only rotor manufacturers in world.

Just one year later, in 2005, VMAC, released the H60 Hydraulic Driven Air Compressor designed to be mounted on the service truck deck. This air compressor was originally named the VMAC PREDATAIR and offered customers hydraulic air compressor system benefits that had not been previously available—the VMAC H60 was and still is less than half the size, half the weight, but with all the power of competitive products.

This was followed in 2008 with the launch of a second PREDATAIR, the VMAC H40 Hydraulic Driven Air Compressor with intelligent digital controls. The VMAC H40 is up to 260 lbs lighter and 6 cubic feet smaller than competitive products, making it the smartest, smallest, and most powerful 40 CFM mobile hydraulic air compressor available.

After releasing the H60 and H40, VMAC received demand from customers, dealers and truck body builders alike, looking for more choice in standalone deck-mounted air compressors. This led to the 2011 launch of the D60 Diesel Engine Driven Air Compressor, originally named the RAPTAIR. In addition to being more compact and lightweight than comparable 60 CFM diesel engine air compressors, the VMAC D60 features innovative engine anti-idling technology. The D60’s state-of-the-art advanced control system automatically shuts the compressor engine down when no air is being used, and automatically restarts the engine when air is needed. This VMAC anti-idling technology allows customers to save fuel, decrease emissions and maintenance costs, and extend truck and equipment life.

Just two years later, in 2013, VMAC expanded its RAPTAIR product line even further to include the VMAC RAPTAIR-MF, now called the Multifunction Power System. The VMAC Multifunction Power System offers over 2000 possible configurations, weighs 400 lbs less than competing multi-power systems, and is equipped with VMAC’s advanced digital controls and anti-idling technology found in the D60.

Then in 2015, VMAC—with significant input from its key industry body builder partners—developed and released the UNDERHOOD-Lite, later called the UNDERHOOD™ 30 Air Compressor, which is the only air compressor system specifically engineered for commercial vans. This version of the UNDERHOOD™ air compressor presented a desirable option for both customers and van upfitters—no longer do they have to settle for a diesel or gas air compressor in the back of their van, which not only takes up precious space for storing tools and other equipment, but is heavy, and exposes operators to toxic fumes and explosion risks.

In the same year, VMAC also designed the G30 Gas Engine Driven Air Compressor, which was 50% smaller, 50% lighter, and 50% more powerful than competitive reciprocating compressor products.

The G30 addition to the VMAC product line completed the deck-mount air compressor suite, which consists of the G30 Gas Engine Driven Air Compressor, the H40 and H60 Hydraulic Driven Air Compressors, the D60 Diesel Engine Driven Air Compressor, and the Multifunction Power System.

2016 was a big year for VMAC, with two notable events: another new innovative product release coupled with a major facility expansion. VMAC launched the VMAC DTM70 Direct-Transmission™ Mounted Air Compressor. This first-to-market direct-transmission mounted PTO driven air compressor is a 70 CFM air compressor that allows customers to reduce truck GVW by up to 260 lbs. Its underdeck positioning frees up to 25 cubic feet on the truck deck.

Later that same year, VMAC poured the first casting in its new in-house foundry, which allows VMAC to expedite R&D innovations, and reduce time to market for new products.

In 2017, VMAC updated the VMAC G30 Gas Engine Driven Air Compressor with the addition of the Honda GX390 engine. VMAC continues to innovate this version of the G30, as it is 23% quieter at high idle, 75% quieter at low idle, offers 15% better fuel economy, and has improved operational performance in hot temperatures and at higher elevations. The VMAC G30 remains the most affordable gas driven rotary screw air compressor available.

2018 was another a busy year of innovation with the release of the DTM70-H, UNDERHOOD™ 40, and CAT-powered Multifunction.

The VMAC DTM70-H is a direct-transmission mounted multi-power system that combines continuous duty compressed air and hydraulic power all in one complete, compact, and easy to install system. This innovative product provides work truck owners and fleets with up to 70 CFM of compressed air, and enough hydraulic power to run a crane or other tools.

The DTM70-H installs 30% faster than competitive deck-mounted hydraulic air systems, requires no drive shaft or transfer case modifications, and frees up truck GVW by as much as 600 lbs. With this latest innovation, the VMAC DTM70-H will become the industry standard for underdeck hydraulic air systems.

The UNDERHOOD™ 40 Van Series Air Compressor replaced the UNDERHOOD™ 30 Van Series and provides customers with even more power. The UNDERHOOD™ 40 weighs just 14 lbs, provides up to 40 CFM at 100% duty cycle, reduces truck GVW by up to 290 lbs, and frees up to 10 cubic feet of cargo space. The UNDERHOOD™ 40 Air Compressor remains the only air compressor specifically engineered for commercial vans and is the industry’s first choice for performance, safety, and installation.

The VMAC Multifunction Power System, powered by CAT, is a new addition to the line of VMAC Multifunction Power Systems, offering customers more choice. Customers will be able to choose a CAT engine with the VMAC Oilman Series Multifunction Power System, which continues to be hundreds of pounds lighter than competing systems.

In early 2019, VMAC released a 24V version of its hydraulic air compressor, specifically built for OEMs. VMAC also began a series of new innovations: increasing the air output of the DTM70-H, creating a cab climate control HVAC system, releasing a DTM70 for RAM trucks, and more (to be announced)!

Auxiliary port driven air compressor system considerations

Today many industrial engines come equipped, or can be ordered with, an auxiliary port (pump drive) that is used to power accessory equipment.  Quite often you will find a hydraulic pump or a standard piston type air compressor mounted there; what isn’t seen much is a rotary screw compressor mounted there.  We’ve had many inquiries asking if there is a compressor available that would meet the heavier duty cycle and air flow requirements for specific jobs.  These range from spray foam, pump priming, air gouging, to air tools and dust collection.  While VMAC does have direct drive, port mounted rotary screw compressors, there are several factors to consider before choosing to mount a rotary screw compressor to that auxiliary port.

Why does hose size affect my compressor airflow?

It is important to consider appropriate sizing of all components of your air system.  If you are investing in an air compressor system, restricting the flow anywhere in your system could make it significantly underperform or cost you a lot more in energy costs to run that compressor over its lifetime.

As air travels from the compressor head to your tool it travels through components such as hoses, fittings, valves, and tanks. Each of these will restrict the flow of air in some way depending on the geometry of each component and the magnitude of the flow passing through it. For example, a long small hose feeding a high air demand tool can result in a high-pressure drop.  The result of this will mean either your compressor is working harder and using more power to keep up with your air demands, or if it can’t keep up, your tool performance will be reduced.  In some cases, where torque or power at the tool is important, you may not be able to complete your work.
