Ingersoll Rand 7801-B Non-Reversible Air Power Motor is engineered to provide dependable pneumatic rotary power for industrial machinery requiring high output torque with moderate operating speeds. As part of the 2200 Series, this air motor delivers 0.85 HP while operating at a free speed of 4,600 RPM. Equipped with a single gear reduction, the 7801-B offers an excellent balance of rotational speed and torque, making it well suited for OEM equipment, automated production machinery, conveyors, processing systems, and industrial applications where compressed-air power is preferred over electric motors.
The 7801-B develops a 4.00 lb-ft stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. Its non-reversible configuration provides consistent single-direction rotation, while the single-stage gear reduction efficiently increases output torque without sacrificing the compact design expected from the 2200 Series.
