PTO Drive Compressors

375-UBI

375-UBI

Description

The 375-UBI takes up no space, frees up your tow hitch, and is cost efficent. In addition, the compressor is lightweight, having fewer parts and runs off a vehicle engine. If the truck runs, the compressor runs when activated!

The advanced design allows you the option to choose up to 375 CFM and up to 110 PSI continuously. Generators, welders, and hydraulic systems may be intergrated with the 375-UBI kit or in-house installation.

Compressor Data and Minimum Chassis Specifications

Compressor input RPM: 2300
Compressor HP: 93
Compressor Torque: 212 lbs/ft (condinuous duty)

Transmission mounted PTO must be capable of 302 lbs/ft intermittent duty and 212 lbs/ft continuous duty. Manual transmissions require the use of a PTO lube pump option with auxiliary lubricant cooler. PTO must be engine rotation.

Engine HP must be capable of running compressor at rated PTO % (i.e.: 140% PTO or 1.4 divided by 2300 compressor input RPM = 1642 engine RPM. Engine must be capable of 93 HP @ 1642 engine RPM).

Back of cab dimensions required for the typical cooler and receiver tank installation is 30.5".
