VMAC unveils transmission-mounted compressor

VMAC’s DTM185 PTO-driven air compressor, mounted directly to transmissions, eliminates the need for an additional driveshaft that’s typically found in underdeck transmissions.

The end result, the company says, helps to control costs, alignment issues, excessive vibration, and downtime.

It delivers 185 cfm at 2,100 rpm and 125 cfm at PTO idle speeds of around 1,200 rpm. That is enough to run two jackhammers simultaneously for several hours, or one jackhammer at PTO idle to maximize productivity and minimize fuel costs, the company says.

In the process, it frees up 70 cubic feet of deck space and lowers gross vehicle weights by up to 1,900 lb. when compared to utility-mount and tow-behind air compressors.

“The DTM185 was designed and engineered by VMAC to meet the demand for a powerful vehicle integrated air compressor with a simplified installation for upfitters,” the company added in a press release.

Mounting kits include a custom-configured Chelsea PTO.

Digital controls include telematics, a built-in soft start, safety controls, automatic cooling and heating, and diagnostics. They can also integrate with Ford’s CAN bus.

Applications include post-2020 Ford F-350 to F-600 Super Duty chassis cabs with 6.7-liter V8 diesel engines, 10-speed (10R140) 2WD automatic transmissions, aft-of-axle fuel tank configurations.
