The Underhood40 Air Compressor from VMAC is designed for both trucks and commercial vans and aimed at operators using small and medium sized air tools.

The upgrade from the Underhood30 to the Underhood40 includes an increase in maximum output from up to 30 CFM to up to 40 CFM at 100% duty cycle.

The VR40 system remains lightweight, weighing 62 pounds, making it up to 290 pounds lighter than the average weight of comparable gas drive air compressors, according to VMAC. The system features an adjustable throttle control to increase or decrease vehicle RPM. This means RPM can be dropped when less air is required, reducing fuel use during operation, lowering vehicle maintenance costs, and extending vehicle lifespan.

Further improvements have been made to the VMAC Underhood40’s digital controller. To start, the VR40 controller has been improved for an easier install than its predecessor, with all wiring pre-built with the connectors, allowing for a plug and play style set up. The digital display box is smaller for easier mounting and also features error tracking, which provides information about system behavior when needed for diagnosing errors. The digital controller includes fan on/off capability, so the system can be cooled when needed, but not overcooled.

The VMAC Underhood40 Air Compressor, Truck Series & Van Series, is backed by a VMAC Lifetime Limited Warranty.
