Ingersoll Rand 7800-B Non-Reversible Air Power Motor is designed to provide dependable pneumatic rotary power for industrial machinery requiring high-speed operation in a single direction. Part of the 2200 Series, this air motor delivers 0.85 HP with a free speed of 18,000 RPM. Equipped with a single gear reduction, the 7800-B is well suited for OEM equipment, high-speed processing machinery, automated production systems, and industrial applications where compressed-air power is preferred over electric motors.
The 7800-B develops a 1.00 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. Its non-reversible design provides consistent rotation in one direction, while the single gear reduction offers an efficient balance of high rotational speed and compact power transmission for demanding industrial environments.
