  • Utility servicing
  • Forklift repair

Commonly used air tools – VMAC UNDERHOOD 30 CFM air compressors can be used for:

  • 3/4“ impact wrench
  • Light chipping hammers
  • Die grinders
  • Tire inflation


Free up to 10 cubic feet 

VMAC UNDERHOOD 30 CFM air compressors free up to 10 cubic feet in the cargo area because the air compressor mounts in the engine compartment. The only space required in the cargo area is 1.7 cubic feet for a combined air/oil cooler and air/oil separator tank.

Reduce vehicle GVW by up to 290 lbs 

VMAC UNDERHOOD 30 CFM air compressors reduce van GVW by as much as 290 lbs.  Less weight means you can carry more, or take advantage of improved fuel economy.

Maximize productivity with up to 30 CFM, 100% of the time 

VMAC UNDERHOOD 30 CFM air compressors use patented rotary screw technology designed to run at 100% duty cycle without stopping, so operators don’t have to wait for their air compressor to fill up an air receiver tank.

Eliminate common safety issues

VMAC UNDERHOOD air compressors are the only 30 CFM air compressors specifically engineered to eliminate safety hazards that van operators face including lifting injuries, toxic fume exposure and gas fires inside the cargo area.


VMAC UNDERHOOD30 on a RAM Promaster Van

The UNDERHOOD30 compressor mounts under the hood of your van. To operate, simply shift your van into park and engage the parking brake. With the engine idling, a simple on/off switch turns on the compressor system. Once on, an electric clutch engages on the compressor, the engine idles up, and the rotary screw compressor delivers a steady, continuous flow of air to your tools.

The WHASP Tank is an integrated cooler/tank that mounts in the cargo area on your van. An air/oil mixture is thrust from the compressor to the WHASP Tank that both cools the air/oil mixture, and separates and then recirculates the oil back to the compressor. The compressed air flows continuously to our auxiliary air receiver tank and onto your air tools.

Throttle control must have two speed operation (base and elevated idle) and must automatically modulate engine RPM depending on air usage.
