VMAC V400049 – Underhood 40 CFM Rotary Screw Air Compressor

Reclaim Your Cargo Space with the VMAC Underhood 40

Transform your work truck’s efficiency with the VMAC V400049 Underhood 40, the ultimate solution for professionals who demand powerful, reliable air without sacrificing valuable cargo space or payload capacity. This revolutionary rotary screw air compressor system mounts directly into the engine compartment of your truck, turning your vehicle’s engine into a robust, on-demand air source. By eliminating the need for a bulky, deck-mounted compressor, the V400049 frees up your entire truck bed for tools, equipment, and materials, while significantly reducing your vehicle’s overall weight and improving fuel economy.

Uncompromising Power and Performance

Don’t let its compact size fool you; the V400049 is an industrial powerhouse. Engineered with advanced rotary screw technology, it delivers a continuous, unwavering 40 CFM at 100 PSI, with a maximum pressure of up to 150 PSI. This impressive output is more than enough to power a 1-inch impact wrench, air jacks, grinders, and a wide range of other demanding pneumatic tools. Unlike reciprocating compressors, the rotary screw design ensures 100% duty cycle, meaning you get consistent air power for as long as your truck is running, without waiting for a tank to fill. This system is the choice for mobile mechanics, tire service technicians, and utility crews who need dependable performance on any job site, in any weather condition.

Intelligent Design, Rugged Durability

The V400049 is a testament to the world-class engineering of its manufacturer, VMAC. Weighing in at only 62 lbs, this system is up to 85% lighter than comparable gas or diesel-powered compressors, helping you stay compliant with GVW regulations and reducing wear on your vehicle. It integrates seamlessly with your truck’s engine, utilizing a sophisticated throttle control system that automatically idles the engine up and down to match air demand, conserving fuel and reducing noise. Built to withstand the harshest environments, the V400049 features robust construction and is part of the extensive line of VMAC Underhood Air Compressors, trusted by fleets worldwide for their unmatched reliability and longevity. Note that this is the core compressor unit and requires a vehicle-specific mounting kit for installation.
