The World’s First Direct-Transmission Mounted PTO Driven Air Compressor

Transmission Mounted Air Compressors

Overview

The VMAC DTM 70 CFM air compressor is a direct-transmission mounted PTO driven air compressor.

This system is the best choice for customers who are concerned with saving space and reducing weight on their service trucks.  The powerful rotary screw air compressor is ideal for operating small to medium sized air tools with high air demand, like 1” impact wrenches, 60 lb jackhammers, backfill tampers, vertical/horizontal grinders and sanders. The system is designed for the Ford F250 to F750 Super Duty 6.7L Power Stroke diesel 4x2 and 4x4 work truck with TorqShift™ Automatic Transmission.

  • Sign installation
  • Oil and gas mobile mechanics

Commonly used air tools – VMAC DTM 70 CFM air compressors 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

Benefits

Maximize productivity with up to 70 CFM, 100% of the time 

VMAC DTM 70 CFM air compressors use patented rotary screw technology designed to run at 100% duty cycle without stopping, so operators don’t have to wait for their air compressor to fill up an air receiver tank.  This maximizes tool performance and eliminates downtime.

Easy operation

VMAC DTM 70 CFM air compressors feature easy to use controls; simply press the on/off button on the digital control box and the system will take care of the rest.  The PTO engages, the compressor turns on, and the throttle control automatically idles the truck engine up and down to match air demand.  For cold climate operation, there is a heater built into the compressor which automatically warms up on the way to the job so it is ready to work when you are.

Easy installation

VMAC DTM 70 CFM air compressors are easy to install, making installation times 50% faster than other under deck air compressor systems.  No modifications are required to the Ford transfer case.  No drive shafts are required to cause alignment issues.  Traditional under deck air compressors for Ford Super Duty trucks are extremely heavy, have poor ground clearance, and require additional sourcing of components.  VMAC mounting kits are application engineered for Ford diesel trucks and include all the necessary components.

Free up to 25 cubic feet

VMAC DTM 70 CFM air compressors free up to 25 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.

Reduce truck GVW by up to 260 lbs

VMAC DTM 70 CFM air compressors reduce truck weight by as much as 260 lbs.  This is because there is no secondary engine to carry around on your truck.  And when compared to other under deck air compressors, at only 150 lbs the DTM70 weighs a fraction.  Less weight means you can carry more, or take advantage of improved fuel economy.

Avoid frustrating breakdowns and maintenance issues

VMAC DTM 70 CFM air compressors are 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

VMAC DTM 70 CFM air compressors are proven to work in any extreme climate.  With an integrated automatic heater, the compressor is ready to work when you are.
