SPEEDAIRE 22UX71 air motor

The SPEEDAIRE 22UX71 is a 0.45 hp air motor delivering 20.5 cfm at 6,000 RPM. It features a 3/8 in shaft and 1/8 in NPT inlet for direct connection to compressed air lines. The aluminum and cast iron housing weighs 1.32 lb and includes a muffler for quieter operation.

Suits low-torque rotary tasks

This motor suits applications needing continuous rotary motion at modest torque, such as agitators, feeders, or small winches. Its 2.75 in-lb maximum torque and 100 psi pressure limit make it unsuitable for high-force requirements. Buyers needing greater torque or variable speed control should look at alternative drive solutions.

0.45 hp at 6,000 RPM defines fit

The 0.45 hp output at 6,000 RPM no-load speed is the primary figure for sizing this motor to a load. Match the motor’s 20.5 cfm maximum flow rate and 100 psi maximum operating pressure against the available air supply. If the application demands more power or a different speed range, this model will not meet the requirement.
