Ingersoll Rand 8228-3B Reversible Air Power Motor is designed to provide reliable pneumatic power for industrial applications requiring bidirectional operation, controlled speed, and increased output torque. Rated at 0.50 HP, this air power motor operates at a free speed of 2,600 RPM and features double gear reduction to enhance torque while maintaining efficient rotary performance. Its reversible configuration allows both clockwise and counterclockwise rotation, making it an excellent choice for OEM machinery, automated production equipment, material handling systems, indexing devices, and industrial processes requiring directional flexibility.
The 8228-3B develops 3.50 ft-lbs of stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. The double gear reduction system delivers greater torque multiplication than higher-speed models while maintaining a balanced operating speed suitable for a wide range of industrial applications.

FAQs:
- Q: Is the Ingersoll Rand 8228-3B reversible?
A: Yes. This model is designed to operate in both clockwise and counterclockwise directions. - Q: What is the advantage of double gear reduction?
A: Double gear reduction increases available output torque while reducing output speed compared to a direct-drive motor, providing improved performance for moderate-speed industrial applications. - Q: What is the rated operating speed?
A: The manufacturer specifies a free speed of 2,600 RPM. - Q: What does the 3.50 ft-lbs stall torque specification indicate?
A: Stall torque is the maximum torque produced when the output shaft is prevented from rotating. It serves as a performance reference and should not be interpreted as continuous operating torque. - Q: What should be verified before installing this motor?
A: Confirm horsepower, operating speed, rotation direction, gear reduction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
