UNDERHOOD® 150 Air Compressors Benefits

Free Up To 80 Cubic Feet On Your Truck Body

UNDERHOOD150 air compressors free up to 80 cubic feet on the truck deck when compared to utility mount options by positioning the air compressor in the engine compartment. No components get installed on the truck deck, which ensures a clean and professional-looking truck with more space for other equipment, tools, and materials. 

Reduce Truck GVW By Up To 1,900 lb

UNDERHOOD150 air compressors reduce truck GVW by as much as 1,900 lb. While utility mount air compressors are heavy and add significantly to truck GVW, UNDERHOOD air compressors are lightweight at only 200 lb. Choosing UNDERHOOD means you can add extra tools and equipment to your truck, carry more materials, take advantage of better fuel economy, or even downsize your truck classification.

Up To 110 CFM, 100% of The Time

UNDERHOOD150 air compressors use patented rotary screw technology designed to run at 100% duty cycle without stopping, so operators can power large pneumatic tools with the push of a button on their truck.

Avoid Frustrating Breakdowns & Maintenance Issues

UNDERHOOD150 air compressors are powerful enough to replace engine-driven utility mount or portable tow-behind air compressors. As a result, less time and money is spent fixing engine issues, and more time is spent making money on jobs.

Free Up Your Hitch

UNDERHOOD150 air compressors allow you to free up your truck hitch so it can be used for towing other equipment. By freeing up your hitch for other equipment, you can haul more materials, eliminate the need for extra trips, or reduce the number of trucks you need on the job site.

Work In Any Climate

UNDERHOOD150 air compressors are proven to work in any extreme climate, making them the air compressor of choice in arctic and desert environments. The compressor is protected in the truck's engine compartment, ensuring it starts in any climate every time.
