28-615-1 Leroi/CompAir Drive Coupler

This 28-615-1 Leroi/CompAir Drive Coupler is a complete flexible power transmission component for industrial air compressors. As an OEM-compatible part for LeRoi (now part of CompAir), this assembly is crucial for connecting the drive source—typically an electric motor or diesel engine—to the compressor’s air-end, ensuring protection against dynamic loads.

Product Quality and Function

• This is a flexible coupling that incorporates an elastomeric element (like a rubber spider or disc) housed within two metal hubs or flanges.
• The assembly’s primary function is to provide high torsional resilience, absorbing the engine’s firing pulses and shock loads that could otherwise damage the precision air-end bearings and rotors.
• It compensates for minor angular, parallel, and axial shaft misalignments, reducing the wear and tear on adjacent rotating components.
• By isolating vibration and dampening torsional shock, the coupler promotes longer service life for the entire compressor drive train.
• This type of flexible coupling is generally maintenance-free, requiring no lubrication, which simplifies routine maintenance for the user.
• It ensures a smooth and continuous transmission of torque under continuous high-demand operation.

Industry Applications and Brands

• Therefore, the 28-615-1 is a vital component for the maintenance and repair of LeRoi / CompAir rotary screw compressors.
• It functions as the critical link in the driveline of various compressor models used in heavy-duty industrial environments.
• The coupler is utilized across applications such as manufacturing, construction, mining, and general industry, where reliable compressed air is essential.
• Maintaining the integrity of this coupler is key to preserving the operational efficiency and extending the working life of the compressor package.
