Direct-Transmission Mounted PTO Driven Multi-Power System


The VMAC DTM70-H Air Compressor is a direct-transmission mounted PTO driven air compressor with hydraulic pump.

This system is the best choice for customers who are concerned with saving space and reducing weight on their service trucks, and who need both air and hydraulic power at the same time. This multi-power system allows customers to operate small to medium sized air tools, as well as a hydraulic crane or other equipment simultaneously. The system is designed for the Ford F250 to F550 Super Duty 6.7L Power Stroke diesel 4×2 and 4×4 work truck with TorqShift™ Automatic Transmission. Truck Mounting Kits 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.

Mounting kits available for: ford-logo

  • Ford F-250 to F-550 Power Stroke Diesel

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

Applications –  Common jobs that use the DTM70-H multi-power system:

  • Commercial tire services
  • Utility servicing
  • Heavy equipment repair
  • Sign installation
  • Mechanics trucks
  • Hydraulic crane trucks
  • Telescopic cranes

Commonly used air tools – VMAC DTM70-H systems can be used for:

  • 1” impact wrenches
  • 60 lb jackhammers/pavement breakers
  • Backfill tampers
  • Vertical/horizontal grinders
  • Sanders
  • OTR tire inflation
  • Many other air tools/applications


Up To 70 CFM. Up To 14.9 GPM

The VMAC DTM70-H uses patented rotary screw technology designed to run 100% of the time without stopping, to maximize operator efficiency on the jobsite.  The system can produce up to 70 CFM @ 100 psi or up to 14.9 GPM @ 3,265 psi, dependent on pump size and engine RPM.

Decrease Truck GVW By Up To 600 LB

The DTM70-H frees up truck GVW by as much as 600 lbs, 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 more tools and equipment to your truck, carry more materials, take advantage of better fuel economy, or even downsize your truck classification.

30% Faster Installations

The DTM70-H is application-engineered for 2017-2018 Ford F250 to F550 Super Duty work trucks with 6.7L Power Stroke diesel, and TorqShift™ 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. Reduced hydraulic plumbing, fittings and hoses compared to other deck-mounted hydraulic air compressors.

Simultaneous Operation

The DTM70-H control system integrates with standard crane controls and a new benefit is both the air compressor and hydraulic pump are designed to run simultaneously. Actual CFM and GPM flow is dependent on pump size and engine RPM.

Free up to 13 cubic feet on your truck body

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 and maintenance issues

The DTM70-H air compressor is powered by a PTO mounted on the truck’s transmission. Because they don’t have their own 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.
