Benefits

Free up to 25 cubic feet on your truck body
UNDERHOOD™ 70 air compressors free up to 25 cubic feet on the truck deck because the air compressor mounts in the engine compartment.  In fact, no components get installed on the truck deck which ensures a clean and professional looking truck, and space for other equipment, tools or materials.

Reduce truck GVW by up to 260 lbs
UNDERHOOD™ 70 air compressors reduce truck GVW by as much as 260 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 70 CFM. 100% of the time. 
UNDERHOOD™ 70 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.  This maximizes tool performance and eliminates downtime.

Avoid frustrating breakdowns and maintenance issues
UNDERHOOD™ 70 air compressors are powered by the truck’s engine.  Because they don’t have their own engine that needs constant maintenance, less time and money is spent on fixing engine issues and more time is spent on jobs making money.

Work in any climate
UNDERHOOD™ 70 air compressors are proven to work in any extreme climate, chosen as the air compressor of choice in arctic and desert environments.  The compressor is protected under the hood of the truck, ensuring it starts in any climate every time.
