Multifunction Power Systems Benefits

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 up to 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 up to 400 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.

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.
