What Is A PTO Driven Air Compressor?

A PTO driven air compressor is an air compressor that’s driven by the power take-off (PTO) of a vehicle. These innovative air compressors are mounted under the vehicle’s deck, resulting in an elegant solution that’s out of sight and mind (until you need it!) Advantages of PTO Driven Air Compressors Render of VMAC’s PTO air […]

What’s the difference between PSI and CFM?

The difference between PSI and CFM is what they measure. PSI measures pressure, while CFM measures volume. PSI and CFM are performance specifications for air compressors and air-powered machinery. Together, they indicate the maximum air volume and pressure produced by an air compressor to power air tools. To better understand the difference between PSI and […]

Rotary Screw

Easy Guide To Rotary Screw Air Compressors (2022 Edition)

Updated: Jan 13, 2022. Rotary screw air compressors operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This reduction in volume results in compressed air, which can then be used to power air tools, inflate tires, or in numerous other applications. […]

Pressure Relief Valves For Air Compressors

Pressure relief valves, or safety valves, are a simple but critical part of any air compressor system. Pressure relief valves control and limit the pressure build-up in a system. If the pressure exceeds the amount allowed by the pressure relief valve, the pressure relief valve will automatically open and release air until the pressure reduces. […]

How To Size An Air Receiver Tank

Many air compressor applications can benefit from installing an air receiver tank. An air receiver tank increases the amount of air available on-demand, allowing for higher duty cycles and more air power. Air receiver tanks are sized in gallons and range from small 5- and 10-gallon tanks to massive tanks that hold thousands of gallons […]

FRL

What Is An FRL – Filter Regulator Lubricator

Air leaving a compressor is hot, dirty, and wet—which can damage and shorten the life of downstream equipment, including valves, cylinders, and air tools. So before compressed air exits the system, it needs to be cleaned and lubricated. That’s where an FRL comes in! An FRL combines a filter, regulator, and lubricator into one component […]
