Ingersoll Rand 3800U Multi-Vane Non-Reversible Air Motor | Series 3800 | 1.45 HP | 220 RPM | 105 (ft-lbs) Starting Torque | 140 (ft-lbs) Stall Torque

Ingersoll Rand 3800U Multi-Vane Non-Reversible Air Motor is engineered to provide dependable pneumatic rotary power for industrial equipment requiring exceptionally high output torque at low operating speeds. Part of the 3800 Series, this air motor delivers 1.45 HP with a free speed of 220 RPM. Its durable multi-vane design converts compressed air into smooth, continuous rotary motion, while the non-reversible configuration provides reliable single-direction operation for demanding OEM machinery, material handling systems, conveyors, industrial mixers, and processing equipment.

The 3800U develops 105 ft-lbs starting torque, providing substantial breakaway force to initiate heavily loaded equipment, and 140 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of low operating speed and high torque output makes the motor well suited for industrial applications requiring controlled rotary motion and dependable pneumatic performance.

FAQs:

• Q: Is the Ingersoll Rand 3800U reversible?
  A: No. This model is a non-reversible air motor designed for continuous operation in one rotational 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 power delivery.
• Q: What is the rated free speed?
  A: The manufacturer specifies a free speed of 220 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 developed 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.
