Six Power Sources, One Quiet Machine

For industrial job sites or residential areas where noise level is a concern, there is no better system. The VMAC Multifunction Power System, powered by a Tier 4F Cat Industrial Diesel Engine, includes everything you need for safe operation on any job site in a single, compact system. Components include an air compressor, generator, welder, booster/charger, PTO with an optional hydraulic pump, and cold climate kit. With noise reduction panels, low and high idle controls, and Standby Mode, operators can safely communicate while working without disturbing the job site or neighbors.

Reduce Truck Maintenance & Fuel Costs

The VMAC Multifunction Power System reduces truck maintenance and improves fuel economy by allowing operators to turn their truck engines off while on the job site. Also, by reducing vehicle weight by up to 140 lb, automatically idling the Cat engine up/down with air demand, and turning the Cat engine off/on with air demand, the VMAC Multifunction Power System allows operators to carry more tools or equipment or improve fuel economy.

Easy To Operate & Switch Between Systems

The VMAC Multifunction Power System allows operators to seamlessly switch between operations without the hassle of complicated controls or maneuvering multiple machines on the job site. This means more time working, improving productivity, and getting customers back to work faster. It is designed for ease of use to run efficiently with only one operator.
