Direct-Transmission Mounted PTO Driven Multi-Power System

The VMAC DTM70-H multi-power system is a direct-transmission mounted PTO driven air compressor with a hydraulic pump.

The DTM70-H system is the best choice for fleet managers and owners who need to save space, reduce weight, and use air and hydraulic power at the same time. The DTM70-H multi-power system allows customers to simultaneously operate small to medium sized air tools alongside a hydraulic crane or other equipment.

Mounting kits available for:

Ford F-250 to F-600 Power Stroke Diesel

VMAC designs truck mounting kits for the easiest possible installation. Working closely with leading truck manufacturers, VMAC ensures that mounting kits do not affect OEM warranties.

Some applications are restricted to specific series and/or models. Please confirm compatible vehicles on VMAC’s Application List.

Variable Air & Steady Hydraulics – One PTO

Use variable air power and steady hydraulic power at the same time with a single PTO port. The DTM70-H uses a priority valve to divert excess hydraulic flow, which allows you to get up to 65 CFM* of compressed air on demand—while simultaneously providing the consistent hydraulic power you need.

Fixed & Variable Operating Modes

The DTM70-H multi-power system allows operators to switch between fixed and variable modes, which reduces engine RPM and minimizes fuel consumption, resulting in fewer emissions and less noise on the job site. Fixed mode maintains a pre-set low engine RPM for running hydraulic equipment and provides a steady rate of compressed air. Variable mode enables engine RPM to increase and decrease automatically based on air demand, while still maintaining steady hydraulic flow. Both modes enable hydraulic equipment to operate at their required speeds.

Decrease Truck GVW By Up To 600 lb

The DTM70-H frees up truck GVW by as much as 600 lb, with no air receiver tank to mount on the truck deck and 50% smaller hydraulic tank sizes required compared to other hydraulic systems. The total system weight is only 180 lb, allowing you to add taller tool cabinets, carry more materials or equipment or take advantage of improved fuel economy while driving to the jobsite.

30% Faster Installations

The DTM70-H is application engineered for 2020+ Ford F-250 to F-600 Super Duty work trucks with 6.7 L Power Stroke diesel, and TorqShift^TM Automatic Transmission (4×4 or 4×2). No modifications are required to the Ford transfer case. No drive shafts are required, which can cause alignment issues. The system also allows for reduced hydraulic plumbing, fittings, and hoses compared to other deck-mounted hydraulic air compressors.

Free Up To 13 Cubic Feet

The DTM70-H multi-power system frees up to 13 cubic feet on the truck deck because the air compressor mounts to the transmission, and the rest of the system mounts under the truck. In fact, no components get installed on the truck deck which ensures a clean and professional looking truck, and space for other equipment, tools or materials.

Avoid Frustrating Breakdowns & Maintenance Issues

The DTM70-H air compressor is powered by a Chelsea® PTO mounted on the truck’s transmission. Because there is no secondary engine that needs constant maintenance, less time and money is spent on fixing engine issues and more time is spent on jobs making money.

Work In Any Climate

The DTM70-H multi-power system is proven to work in any extreme climate. With an integrated automatic heater, the system is ready to work when you are.
