    Precision ground asymmetric profile delivers an optimal combination of capacity and power. Rotor speed range: 15 m/s to 50 m/s on male rotor tip.


    Several built-in volume ratios offer a range of pressure ratios meeting specific application requirements.


    AGMA Class 11 Gears allow for a variety of internal gear ratios contributing to design optimization and operation economy.


    Heavy duty double-wall cast iron casing provide for structural rigidity, pressure integrity and low noise.

    Drive Adaptor

    Available drive adaptors (flywheel adaptors or base mounted) offer a convenient means to match up the air end with the drive unit.


    The steel input shaft can be easily adapted/coupled to the driver with a variety of methods: keyed fit, mechanical locking or shrink-fit coupling hub. Drivers used include natural gas and diesel engines; 1800 rpm, 2100 rpm motors; and variable speed drives.


    The anti-friction bearings are manufactured from all-steel (no plastic or “yellow metal” cages) construction for superior durability. Tapered roller bearings absorb thrust and radial loads; while straight roller bearings handle opposite end radial loads both contributing to the optimal performance of the rotors, even in the harshest of conditions.

    Capacity Controls Options

    Capacity controls are an option offered on several models. These controls allow gases that have been only slightly compressed to bypass back into the suction head. Capacity can be manually adjusted or automatically controlled based on pressure signal.


    Sullair Air & Drill Compressor air ends are warranted for two years against defects in materials and workmanship.
