ACT4.9UN Reich OEM Drive Coupler

The ACT4.9UN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 4.9. This coupling is specified in portable air compressor platforms from Ingersoll Rand and Doosan, serving the engine-to-airend connection in mid-range portable units.

ACT4.9 couplers handle the torque demands of IR and Doosan portable compressors in the P-series range. The elastomeric element absorbs diesel engine vibration while transmitting torque smoothly to the compressor airend. In portable compressor service where machines are transported frequently and operate across varying loads, coupler integrity is essential for machine reliability.

The ACT4.9UN is a direct replacement for equipment originally fitted with this coupling. This coupling has multiple hub options – verify your configuration before ordering. Install per the compressor service manual.
