UNDERHOOD™ 40 Engine Mount Air Compressor For Vans
The UNDERHOOD™ 40 rotary screw air compressor system is the ultimate solution for commercial van operators who use small air tools for light-duty applications. This belt-driven air compressor mounts under the van’s bonnet and solves common safety issues found with traditional air compressors in vans.
VMAC has partnered with Techni Systems to engineer mounting kits for vehicles commonly found in the UK. Working closely with leading van manufacturers, Techni Systems ensures mounting kits do not affect OEM warranties.
Mounting Kits available for:

- Renault Master FWD
- Nissan NV400 FWD
- Opel Movano FWD
- Vauxhaull Movano FWD
- MAN TGE RWD
- Volkswagen Crafter RWD
Some applications are restricted to specific series and/or models. Please confirm compatible vehicles with Techni Systems.
Applications – Common jobs that use the UNDERHOOD™ 40 air compressor are:
- Tyre servicing
- Utility servicing
- Forklift repair
Commonly used air tools – UNDERHOOD™ 40 air compressors can be used for:
- 3/4″ impact wrench
- Light chipping hammers
- Die grinders
- Tyre inflation
Free up to 0.3 cubic metres in your cargo area
UNDERHOOD™ 40 air compressors free up to 0.3 cubic metres in the cargo area because the air compressor mounts in the engine compartment, beneath the bonnet. The only space required in the cargo area is 0.05 cubic metres for the WHASP tank—a combined air/oil cooler and separator.
Reduce vehicle GVW by up to 130 kg
UNDERHOOD™ 40 air compressors reduce GVW by as much as 130 kg. Choosing a lightweight air compressor means you’ll be able to add more tools and equipment to your vehicle, carry more materials, or take advantage of better fuel economy.
Up to 68 m3/h (40 CFM). 100% of the time
UNDERHOOD™ 40 engine mount 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.
Eliminate common van safety issues
UNDERHOOD™ 40 air compressors are specifically engineered to eliminate safety hazards that van operators face, including lifting injuries, toxic fume exposure and gas fires inside the cargo area.
The UNDERHOOD™ 40 compressor mounts under the bonnet of your van. To operate, simply shift your vehicle into park and engage the parking brake. With the engine idling, a simple on/off switch turns on the compressor system. Once on, an electric clutch engages on the compressor, the engine idles up, and the rotary screw compressor delivers a steady, continuous flow of air to your tools.
The WHASP Tank is an integrated cooler/tank that mounts in the cargo area on your van. An air/oil mixture is thrust from the compressor to the WHASP Tank that both cools the air/oil mixture, and separates and then recirculates the oil back to the compressor. From there, filtered compressed air flows continuously to the air receiver tank, if installed, or directly to your air tools.
The throttle control automatically modulates engine RPM, depending on air usage. The UNDERHOOD™ 40 throttle control is adjustable and includes two-speed operation.
