UNDERHOOD® 40 Air Compressors Benefits

Free Up To 10 Cubic Feet In Your Cargo Area

UNDERHOOD40 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 lb

UNDERHOOD40 air compressors reduce van GVW by as much as 290 lb. Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your van, carry more materials, or take advantage of better fuel economy.

Up To 40 CFM*, 100% Of The Time

UNDERHOOD40 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 a large air receiver tank.

Eliminate Common Safety Issues

UNDERHOOD40 – Van Series air compressors are the only 40 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.

Advanced Digital Controls & Telematics*

The UNDERHOOD40 with VMAC’s advanced digital controls is complete with telematics, built-in soft start, safety controls, and enhanced diagnostics. VMAC’s advanced digital controls integrate with the vehicle and provide more information about your compressor than ever before, making it easy to monitor the performance of your system and plan maintenance intervals. 

* Available for most popular 2023+ model year commercial vans; see application list for details.
