02250191-784 Sullair OEM Drive Coupler

The 02250191-784 Sullair OEM Drive Coupler is an OEM coupling for Sullair stationary rotary screw air compressors. This drive coupler transmits motor torque to the airend while isolating vibration between the two components.

Sullair stationary compressors are workhorses in manufacturing and industrial compressed air systems, running extended hours under constant loading. The drive coupler in these installations operates within an enclosed compressor package where ambient temperatures are elevated by motor heat and compression energy. The 02250191-784 is specified for a particular Sullair platform where the coupling must perform consistently in this high-temperature environment without premature degradation of the elastomeric element.

This factory part installs in the original position with no modifications. Disconnect power before service, lock out the motor, and remove the coupling guard to access the element. Inspect motor and airend shaft alignment before installing the replacement and verify smooth rotation by hand before energizing.
