UP TO 70 CFM 100% OF THE TIME
UNDERHOOD 70 air compressors use patented rotary screw technology designed to maintain 100% of the required tool CFM, so operators don’t have to wait for their air compressor to fill an air receiver tank. This maximizes air tool performance and eliminates downtime.
DECREASE 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.
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. No components get installed on the truck deck, which ensures a clean and professional-looking truck, and space for other equipment, tools, or materials.
