UNDERHOOD™ 150 Air Compressors



Aug2018 - MWTS

The UNDERHOOD™ 150 air compressor system is the best choice for customers who have concerns with space and weight on their service or utility truck.

UNDERHOOD™ 150 Air Compressors

The powerful rotary screw air compressor is ideal for operating large-size air tools like post-pounders or jack hammers. This means that it replaces large utility-mount or portable tow-behind air compressors.

Truck Mounting Kits

VMAC engineers truck mounting kits for the easiest possible installation.  Working closely with leading truck manufacturers, VMAC ensures that mounting kits do not affect OEM warranties. Mounting kits available for:

  • Ford F-250 to F-750 Power Stroke Diesel
  • Ford F-250 to F-750 Gas
  • RAM 3500 to 5500 Cummins Diesel

  • Pressurizing gas lines
  • Fiber optic cable shooting
  • Sand blasting
  • Sprinkler irrigation
  • Monument engraving
  • Road repair/crack sealing
  • Utility servicing

Commonly used air tools – UNDERHOOD™ 150 air compressors can be used for:

  • 90 lb jackhammers/pavement breakers

Free up to 80 cubic feet on your truck body
UNDERHOOD™ 150 air compressors free up to 80 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.  Utility mount air compressors are large and take up value space on trucks.

Decrease truck GVW by up to 1,900 lb
UNDERHOOD™ 150 air compressors reduce truck GVW by as much as 1,900 lbs. Utility mount air compressors are heavy and add significantly to truck GVW. Choosing a lightweight UNDERHOOD™ air compressor means you’ll be able to add more tools and equipment to your truck, carry more materials, take advantage of better fuel economy, or even downsize your truck classification.

Avoid frustrating breakdowns and maintenance issues
UNDERHOOD™ 150 air compressors are powerful enough to replace engine-driven utility mount or portable tow-behind air compressors.  This means less time and money is spent on fixing engine and chassis issues and more time on jobs making money.

Free up your hitch
UNDERHOOD™ 150 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 of materials to the jobsite, make only one trip to the jobsite, or reduce the number of trucks you need on the jobsite.

Work in any climate
UNDERHOOD™ 150 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 in the engine compartment of the truck, ensuring it starts in any climate every time.
