02250210-122 Sullair OEM Drive Coupler

The 02250210-122 Sullair OEM Drive Coupler is a coupling for Sullair portable rotary screw air compressors. This coupling uses a Reich Arcusaflex ACH-series design, indicating a heavy-duty application within Sullair’s portable compressor range where higher torque capacity is required.

Sullair compressors equipped with ACH-class couplers are larger portable units – machines in the 375+ CFM range that power heavy-duty pneumatic tools and equipment on construction and industrial sites. At this power level, the coupling handles substantial torsional loads, and element condition has a significant impact on drivetrain reliability.

The 02250210-122 is a direct factory replacement. Given the higher torque involved with ACH-class couplers, precise alignment during installation is especially critical. Follow Sullair’s service procedure exactly, use calibrated torque equipment, and verify alignment with appropriate measuring tools before startup.
