Free Up Space

VMAC Multifunction Power Systems leave more space on your truck deck or cargo area because they combine multiple functions into one compact system. The overall system size is six cubic feet smaller than other leading multi-power brands and designed to fit on the side pack of a service truck with a slider.

Reduce Weight

VMAC’s Multifunction reduces truck GVW by 410 lb. Choosing a lightweight multi-power system 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.

Reduce Truck Maintenance & Fuel Costs

Multifunction Power Systems save truck maintenance costs and improve fuel economy by allowing you to turn your truck engine off while on the job site. The control system not only automatically idles the system’s engine up/down with air demand, it also turns the engine off/on with air demand.

Easy To Operate & Switch Between Systems

VMAC Multifunction Power Systems allow you 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 your customers back to work faster. It is designed for ease-of-use, to run efficiently with only one operator.

Improve Safety With Noise Reduction Technology

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.

Control System

Remote mounted control/digital display box with electronic key switch and LCD for compressor on/off controls, observing system status, and adjusting parameters
Remote mounted generator/welder control box with genset voltage meter and selector, welding current and ARC force control
Socket for optional remote welding control
Integrated voltage sensing interlock feature ensures safe welding/battery boosting and protects equipment by disabling the genset in unsafe conditions
Separate selector switches engage compressor and generator; either function can be selected at any time
Multi-speed throttle control responds to operating function and air demand
With compressor-only selected, and sustained periods of no air use, the control system will shut down the engine (Standby Mode); the engine will not shut down automatically with generator selected
