Ingersoll Rand 7803-B Non-Reversible Air Power Motor is designed to deliver dependable pneumatic rotary power for industrial machinery requiring increased output torque and controlled operating speeds. As part of the 2200 Series, this air motor produces 0.85 HP while operating at a free speed of 1,200 RPM. Equipped with a double gear reduction, the 7803-B provides substantially higher torque than single-stage models, making it well suited for OEM equipment, automated production machinery, material handling systems, process equipment, and industrial applications where compressed-air power is preferred.
The 7803-B develops a 16.00 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. Its non-reversible design provides reliable single-direction operation, while the double-stage gear reduction efficiently lowers output speed and increases available rotary force for demanding applications.

FAQs:
- Q: Is the Ingersoll Rand 7803-B reversible?
A: No. This model is a non-reversible air motor designed for continuous rotation in one direction. - Q: What is the benefit of double gear reduction?
A: Double gear reduction uses two reduction stages to decrease output speed while providing substantially greater output torque than a single-stage reduction. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 1,200 RPM. - Q: What does the stall torque rating represent?
A: Stall torque is the maximum torque the motor develops when the output shaft is prevented from rotating under load. - Q: What should be verified before installation?
A: Confirm horsepower, free speed, rotation direction, gear reduction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
