Ingersoll Rand 1801U Non-Reversible Multi-Vane Air Motor is engineered to deliver dependable pneumatic rotary power for industrial equipment requiring substantial output torque at reduced operating speeds. Producing 1.35 HP with a free speed of 435 RPM, this 1801 Series air motor features a durable multi-vane design that provides smooth, continuous power delivery for demanding industrial applications. Its non-reversible configuration ensures reliable single-direction operation, making it an excellent choice for OEM machinery, conveyors, industrial mixers, processing equipment, material-handling systems, and other compressed-air-powered equipment requiring controlled rotary motion.
The 1801U develops a 41.0 lb-ft starting torque, providing excellent breakaway force for starting heavier loads, and a 55 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The combination of lower operating speed and increased torque makes this air motor well suited for demanding applications requiring dependable pneumatic performance and sustained rotary output.

FAQs:
- Q: Is the Ingersoll Rand 1801U reversible?
A: No. This model is a non-reversible air motor designed for continuous operation in one direction. - Q: What is a multi-vane air motor?
A: A multi-vane air motor uses sliding vanes inside a rotor to convert compressed air into smooth, continuous rotary motion with consistent torque delivery. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 435 RPM. - Q: What is the difference between starting torque and stall torque?
A: Starting torque is the torque available to begin rotating a load from rest, while stall torque is the maximum torque the motor develops when the output shaft is prevented from rotating. - Q: What should be verified before installation?
A: Confirm horsepower, free speed, rotation direction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
