Ingersoll Rand 8204-A Non-Reversible Air Power Motor is engineered to deliver dependable pneumatic rotary power for industrial applications requiring a combination of high operating speed and moderate output torque. Producing 2.0 HP with a free speed of 3,500 RPM, this air motor incorporates a single gear reduction design that provides an effective balance between rotational speed and torque output. Its non-reversible configuration is intended for equipment operating continuously in one direction, making it suitable for OEM machinery, production equipment, conveyors, material handling systems, spindle drives, and other compressed-air powered industrial applications.
The 8204-A develops a 10.20 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of high horsepower, moderate-to-high operating speed, and single gear reduction makes the motor well suited for industrial equipment requiring reliable pneumatic performance and consistent rotary output.

FAQs:
- Q: Is the Ingersoll Rand 8204-A reversible?
A: No. This model is a non-reversible air power motor intended for continuous operation in one rotational direction. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 3,500 RPM. - Q: What does single gear reduction mean?
A: Single gear reduction uses one stage of gearing to reduce output speed while increasing available output torque compared to a direct-drive configuration. - Q: What does the 10.20 ft-lbs stall torque rating indicate?
A: Stall torque is the maximum torque the motor develops when the output shaft is prevented from rotating. - Q: What should be verified before installation?
A: Confirm horsepower, free speed, gear reduction, rotation direction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
