SPEEDAIRE Rotor Blade Pack
This pack contains six SPEEDAIRE rotor blades designed for compatible air compressors and vacuum pumps. They serve maintenance teams and equipment operators who need replacement blades to keep pneumatic systems running. The blades match Grainger part number 21AA57 and carry the SPEEDAIRE brand. This item is restricted from sale in California.
Compatibility check before ordering
Verify that your compressor or vacuum pump accepts SPEEDAIRE rotor blades and matches the Grainger 21AA57 reference. Confirm the blade count required by your specific model, as this pack supplies six pieces. No series designation applies, so cross-reference the manufacturer service documentation for exact fitment.
Sustained-load behaviour
Under continuous operation the blades maintain consistent contact with the cylinder wall to sustain compression efficiency. Material composition resists wear during extended duty cycles, reducing the frequency of blade replacement. The six-piece pack supports a full rotor change, minimising downtime during scheduled overhauls.
