Benefits
Free up to 23 cubic feet on your truck deck
UNDERHOOD™ 40 air compressors free up to 23 cubic feet on the truck deck or cargo area because the air compressor mounts in the engine compartment. The only space required on the truck deck or cargo area is 1.7 cubic feet for a combined air/oil cooler and air/oil separator tank.
Decrease truck GVW by up to 290 lbs
UNDERHOOD™ 40 air compressors reduce truck GVW by as much as 290 lbs. Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your truck, carry more materials, or take advantage of better fuel economy.
Up to 40 CFM. 100% of the time
UNDERHOOD™ 40 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.
