Going Green with VMAC: Lightweight & Fuel Saving Air Compressors

Taking Fleets & Equipment Green in 2017

As states, provinces, and countries continue to press forward with climate change action plans and green initiatives, it’s clear that products and technologies that save fuel and reduce emissions will continue to gain in popularity. A particular focus is on reducing the carbon footprint of commercial vehicles and their equipment.

One example of a state’s policy that has fostered change in local commercial vehicle fleets is California. Within the last year the state has unveiled its climate change mandate. California’s goal is to reduce carbon emissions 40% by 2030, and greenhouse gas emissions 80% by 2050, down from 1990 levels. It’s no coincidence that many California companies are upgrading their fleets to plug-in hybrid electric technology at this time. Organizations that have recently announced fleet upgrades include the City of Long Beach, Southern California Edison, and San Diego Gas & Electric Company, which signed a memorandum of understanding with XL Hybrids, developer of hybrid truck solutions, for up to 110 new vehicles over the next 3 years.

With many changes happening with various federal and state compliance requirements, fleet professionals are turning to industry associations for support in navigating the changing landscape. The Green Truck Association, an affiliate division of the National Truck Equipment Association, is one such organization providing members with resources on technologies that aid in increasing environmental sustainability and operational efficiency. This includes encouraging the use of fuel sources aside from gas and diesel, such as natural gas or electricity, and also choosing lightweight and fuel saving technology.

Fuel Saving & Lightweight Air Compressors

With the demand for green and efficient equipment on the rise, VMAC has developed a line of lightweight and fuel-saving air compressors, including the UNDERHOOD™ 70 – Green Series Air Compressor, as well as the Diesel Driven Air Compressor, and the Multifunction Power System. Each of these air compressors and multifunction power systems is lightweight, reducing gross vehicle weight (GVW) by hundreds of pounds (compared to competing systems). The U.S. Environmental Protection Agency (EPA) estimates that for every 100 lbs of weight saved, fuel economy can be improved by up to 2%.

In addition, these mobile air compressors and multifunction power systems are equipped with VMAC’s intelligent digital control system, which reduces idle time of trucks and equipment on the jobsite. These controls automatically shut off your engine when air isn’t being used, and then automatically turn the engine back on when you need to get back to work.

Big Issues Caused By Overweight Commercial Vans

Commercial van weight can have significant impacts on any service truck business, especially in the United States. Heavy vans have to follow tighter regulations, undergo more inspections, and can face costly fines in some jurisdictions. Let’s break down what you need to know about weight and why extra weight on commercial vans can be a big problem.

What is GVWR?

Commercial van gross vehicle weight ratings (GVWR) and payloads can differ from vehicle to vehicle.  It is important to know what you’re working with when specifying or upfitting a specific commercial van.

According to, gross vehicle weight rating is the vehicle’s maximum safe weight that should not be exceeded.  Weight calculations include curb weight, additional equipment that’s been added, the weight of cargo and the weight of passengers.  A vehicle’s GVWR never changes.

GVWR vs. Payload

GVWR should not to be confused with payload capacity.  GVWR includes the vehicle’s unloaded curb weight, passengers’ weight and cargo weight. Payload capacity is the difference between GVWR and vehicle weight.  For example: If a vehicle’s GVWR is listed at 10,000 lb and the vehicle’s weight is 6,000 lb (empty), then its payload capacity is 4,000 lb.

Make & Model (Highest Capacity Model)GVWR (Maximum)*Payload (Maximum)*

RAM Promaster City5,395 lb1,901 lb
Ford Transit10,360 lb4,640 lb

FMCSA Regulations Apply Over 10,000 lb

All commercial drivers of vehicles that perform interstate work in the USA and have a gross vehicle weight rating of 10,001 lb or more are required to follow Federal Motor Carrier Safety Administration (FMCSA) regulations. These regulations are enforced by the Department of Transportation (DOT), and are outlined in Title 49, Part 300 to 399 of the Code of Federal Regulations—an exhausting 734-page document of rules that must be followed.

FMCSA has many regulations for overweight commercial vans. For example, interstate drivers must:

  • Be at least 21 years old
  • Possess a DOT Medical Examiner certificate
  • Obtain and display a USDOT number
  • Follow Hours of Service requirements
  • Maintain proper records
    • Pre- and post-trip inspections
    • Accident reports
    • Vehicle maintenance records
  • Receive an annual inspection
  • And more…

Individual states set their own intrastate commercial vehicle regulations, but these regulations tend to be similar to the interstate guidelines. For example, 37 states require a DOT Medical Examiner certificate, while most include reporting, inspection, accident recording, and hours of service rules.

For many operators, the easiest way to avoid the hassle and paperwork of FMCSA regulations is to ensure their vehicle has a GVWR that is consistently under 10,000 lb. While most commercial vans fall into this category, the Ford Transit, RAM Promaster, and Mercedes-Benz Freightliner Sprinter each have a GVWR of over 10,000 lbs.

Fines For Overweight Vans

Overweight vans can also result in hefty fines. According to Texas Department of Motor Vehicles, fines for on-the-road weight violations range from $100 to $10,000 for first offence.  Fines double on subsequent violations within a year.  Fines and other punishments vary in severity from state-to-state, and can even include prison time.

According to Connecticut General Assembly, criminal charges may be brought against the owner or operator of an overweight vehicle if the weight of the vehicle is the proximate cause of a motor vehicle accident that results in death.

Summary of GVWR Issues

To recap the issues and most important information surrounding GVWR:

  • GVWR never changes.
  • Additional regulations apply for vans over 10,000 lb.
    • Inspections, driver requirements, record keeping, and more.
  • Monetary fines may be imposed.
  • Prison time and criminal charges are possible.
  • Business operations will likely be affected.

With these important issues in mind, it makes sense to reduce the weight of vans by purchasing low-weight vehicles and incorporating the lightest components possible.

Air Compressor Solutions for Reducing Van Weight

Service vans that require compressed air for pneumatic tools can reduce weight by using UNDERHOOD™ air compressors.  Traditional air compressors mounted in the cargo area can weigh as much as 375 lb., while the UNDERHOOD™ rotary screw air compressor weighs only 85 lbs. This system increases the available payload by up to 290 lbs.

UNDERHOOD™ is the only air compressor specifically engineered for commercial vans. These 40 CFM rotary screw compressor systems by VMAC are available for the most popular commercial van models.  For further benefits of weight savings in vans, check out VMAC’s previous article “Air power: Just why does air matter to commercial van operators”.
