100% Duty Cycle
VMAC’s powerful rotary screw compressor provides continuous high volume air to run a wide range of pneumatic tools including impact wrenches, grinders, pavement breakers, air guns and post pounders. The UNDERHOOD is perfect for mechanic’s trucks, tire service trucks, and road maintenance vehicles.
High Performance in Extreme Weather Conditions
The UNDERHOOD is the best-performing air compressor on the market in extreme hot and cold climates. It is engineered specifically to handle temperatures other compressors breakdown in. They can be found in the Australian Outback and the Alaskan Slope.
Free Up Space – Maximize Payload
The VMAC UNDERHOOD air compressor system is fully integrated with your truck’s engine, eliminating a second engine and decreasing maintenance costs. It also piggybacks on your truck’s cooling system, so there is no need for extra fluids. The UNDERHOOD leaves no footprint in your vehicle’s cargo area, freeing up space for transportation, tools and equipment.
Make Operations Safer
No need to perch precariously in the back of truck when using the VMAC UNDERHOOD. It keeps boots on the ground and workers safer.

VR Rotary Screw Compressor
Small, light and very powerful. Rotary screw compressors deliver more air than older, reciprocating piston style compressors. 100% duty cycle means more uptime. Driven by your truck’s engine gives you the advantage of not having to bring extra fuel to the job site, or maintain and insure a separate trailer just for your air needs.
Drive System
The compressor is driven by its own serpentine belt. The drive system is mounted forward of the OEM belt and uses idlers and tensioners to exacting tolerances. OEM drive systems have limited capacity for further horsepower draws and add side-loading to aftermarket pulleys. The VR drive system is designed specifically to match the horsepower and alignment of the compressor.
Air/Oil Separator Tank
Required to separate compressor oil from compressed air, the tank mounts safely to your truck’s frame rail. There is no need to mount a bulky receiver tank that takes up payload.
Oil Cooler
Liquid to liquid or air to liquid, depending on the system. The compressor cooler mounts in the engine compartment and out of the way.
Engine Speed/Throttle Control
The system uses an engine speed control that automatically adjusts engine RPM to respond to air consumption demand. This control device provide the following benefits:
- instant response to air flow demands
- reduction of standby noise
- reduction of cooling system load
- fuel conservation when not using air
