Ingersoll Rand 7801-1B Non-Reversible Air Power Motor is designed to deliver reliable pneumatic rotary power for industrial equipment requiring a balance of operating speed and output torque. Producing 0.85 HP with a free speed of 4,600 RPM, this air motor features a single gear reduction that efficiently transfers power while maintaining moderate rotational speed. It is well suited for OEM machinery, automated manufacturing systems, industrial processing equipment, conveyors, and other compressed-air powered applications requiring dependable single-direction operation.
The 7801-1B develops a 4.00 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. Its non-reversible configuration provides consistent one-direction operation, while the single-stage gear reduction offers an effective combination of speed and usable torque for a broad range of industrial drive applications.
