SPEEDAIRE 21AA67 Air Ratchet
The SPEEDAIRE 21AA67 is a 1/2 inch drive air ratchet designed for general duty fastening tasks. It delivers 70 ft-lb of fastening torque at a free speed of 180 RPM. The tool requires a compressed air supply and suits mechanics needing a compact powered wrench.
Air supply and hose requirements
Operation demands 16 cfm air consumption at 90 psi with a minimum pressure of 50 psi. A 1/4 inch NPT female air inlet connects to a supply hose of at least 3/8 inch diameter. Bottom exhaust directs air away from the work area during use.
Sustained operation characteristics
The ratchet maintains its 70 ft-lb torque rating within the 50 to 90 psi pressure range during continuous fastening. Its 2.5 lb weight and 10 inch overall length help reduce operator fatigue over extended periods. Ball detent retainer secures sockets reliably throughout the job.

Questions about this item
How long can the ratchet sustain 70 ft-lb torque before the 16 cfm air demand outruns my compressor?
At 90 psi the tool draws 16 cfm continuously; a compressor that cannot maintain that flow will cause torque to drop during extended use.
What noise and heat should I expect when running the ratchet all day at 180 RPM?
Exhaust exits from the bottom, directing sound and warm air away from the operator during prolonged operation.
What minimum hose size and air pressure must my shop supply for this 1/4 in NPT ratchet to work?
Use at least 3/8 in hose and supply 50 to 90 psi at the 1/4 in NPT female inlet for proper performance.
