DTM PTO Driven Air Compressor

The VMAC DTM70 is a PTO driven direct transmission mounted rotary screw air compressor, the first of its kind on the market. It mounts directly to the PTO on the transmission of any 4WD or 2WD Ford Super Duty F250-F550 truck with 6.7L Power Stroke diesel. It has all the benefits of a traditional under deck, without the installation hassles – no transfer case modifications, no drive shafts, and no warranty concerns.

VMAC Lifetime Warranty

70 CFM. 100% of the time. 1
The VMAC DTM70 will reduce your job times significantly. With up to 70 CFM and up to 175psi at 100% duty cycle, you will never wait for air again. Your air tool’s performance and operator’s experience will be the only thing governing your job completion time.

Reduce commercial tire change-overs by 45 minutes.2
The powerful VMAC rotary screw air compressor ensures your machine works as fast as you do. Because you never have to wait for air, you can just work. And with up to 70 CFM available continuously you have enough air power to simultaneously fill a tire and remove lug nuts from another tire at the same time. Get your jobs done faster. Get your customers back on the road faster. Get more jobs done in a day.

50% faster install time on Ford diesel trucks.3
Traditional under deck air compressors for Ford Super Duty diesel trucks are extremely heavy, have suspect ground clearance, require additional sourcing of components, and installations are very complicated, taking upwards of 40 hours. And, in the case of Ford Super Duty 4x4 trucks, requires the modification of the Ford transfer case.

The VMAC DTM70 provides you with the same under deck convenience, but without the extreme installation time and headaches. With all necessary components included in the mounting kit, installations can be completed in as little as 12-14 hours.

Easy to operate
How easy? Simply press the on/off button on the digital control box. The control system will take care of the rest! If something isn’t right, the display box will tell you. 4
