Rotary Vane Air Gearmotor
The Ingersoll-Rand rotary vane air gearmotor delivers 0.34 hp at 450 RPM with a maximum torque of 71 in-lb. It is built for industrial automation tasks that require consistent pneumatic power. The flange mount and 3/8 inch shaft suit direct coupling to driven equipment. This unit suits maintenance teams and OEM integrators needing a compact air-driven gearmotor.
Sustained Load Behaviour
Rated air consumption of 18 scfm at 18 cfm flow supports continuous operation at the stated output. The steel housing and 33:1 gear ratio are designed to handle the rated torque without overheating up to the maximum ambient temperature of 150 degrees F. Lubricated supply air maintains vane sealing and gear life during extended duty cycles.
Shaft and Mount Compatibility
The 3/8 inch diameter shaft with a 1 inch length and flange mount pattern set the mechanical interface. Buyers must verify that the driven load matches the 71 in-lb torque limit and that the 1/4 inch NPT inlet can supply 18 scfm at operating pressure. Systems needing a different shaft size, rotation direction, or mount style cannot use this motor.

Questions about this item
How much air does the 0.34 hp rotary vane motor consume when running continuously?
The motor draws 18 scfm at maximum flow, so a compressor and supply line rated for at least that volume are needed for all-day operation.
What compressed-air fittings and supply pressure must I already have to install this flange-mount gearmotor?
It requires a 1/4 in NPT inlet connection and a compressed-air source capable of delivering 18 cfm at the pressure the motor is rated for.
Will the 3/8 in output shaft and 33:1 gear ratio mate with the pulleys and brackets on my older M004-series equipment?
The 3/8 in diameter, 1 in long shaft with a standard keyway matches legacy M004 mounts, and the 33:1 reduction keeps torque at 71 in-lb for existing drive components.
