What this air polisher does
The SPEEDAIRE 21AA94 is a 7 in rotary air polisher built for medium-duty buffing and polishing work. It delivers 0.75 hp and spins at 2500 RPM to remove swirls, oxidation and light scratches on painted or clear-coated panels. Technicians who need a right-angle grip with a side handle for control will find the layout familiar and stable. The tool ships new and carries California Proposition 65 warnings for cancer and reproductive harm.
Air supply limits you must meet
The polisher consumes 24 cfm at 90 psi and requires a 1/4 in NPT inlet fed by at least a 3/8 in hose. If the compressor or line cannot sustain that flow the motor will stall under load and the pad speed will drop below the rated 2500 RPM. The rear exhaust directs air away from the work surface but adds noise behind the operator. No regulator or filter is included so plan the supply side before mounting the tool.
The spindle thread that decides fit
The output shaft uses a 5/8 In.-11 spindle thread so only backing plates and pads with that exact thread will mount securely. A 7 in pad is included and matches the maximum disc diameter but any replacement must share the 5/8 In.-11 spec or the tool cannot be used. Verify the thread on your existing accessories before purchasing.

Questions about this item
Should I choose the 7 in pad or a different size for this polisher?
The SPEEDAIRE 21AA94 includes a 7 in pad and supports a maximum disc diameter of 7 in, so no other pad sizes fit this tool.
What does the 2,500 RPM rating mean when the polisher is running on the job?
At 90 psi the motor spins at up to 2,500 RPM, giving a rotary polishing motion suited for medium-duty buffing tasks.
How does the 1/4 in NPT air inlet and 24 cfm consumption limit compressor choice?
You need a compressor that can deliver 24 cfm at 90 psi through a 3/8 in minimum hose to the 1/4 in NPT inlet without pressure drop.
