Ingersoll Rand 3800S Multi-Vane Non-Reversible Air Motor | Series 3800 | 1.45 HP | 255 RPM | 88 (ft-lbs) Starting Torque | 118 (ft-lbs) Stall Torque

Ingersoll Rand 3800S Multi-Vane Non-Reversible Air Motor is designed for industrial equipment requiring substantial pneumatic torque at a controlled low operating speed. Part of the 3800 Series, this motor delivers 1.45 HP with a free speed of 255 RPM. Its multi-vane design converts compressed air into continuous rotary motion, while the non-reversible configuration supports machinery that operates consistently in one rotational direction.

The 3800S provides 88 ft-lbs starting torque, giving buyers a reference for the torque available as the motor begins moving a connected load. Its 118 ft-lbs stall torque identifies the maximum torque developed when the output shaft is prevented from rotating. This low-speed, high-torque combination is suited to compatible OEM machinery, conveyors, mixers, processing equipment, and material handling systems where dependable single-direction pneumatic drive power is required.

Applications:

• OEM machinery requiring high-torque, single-direction pneumatic rotary power.
• Industrial mixers and agitators compatible with the stated speed and torque ratings.
• Conveyor and material handling equipment.
• Processing and production machinery requiring controlled low-speed rotation.
• Replacement installations where the 3800S mounting, shaft configuration, dimensions, and performance ratings match the existing motor.

FAQs:

• Q: Is the Ingersoll Rand 3800S reversible?
  A: No. This model is specified as a non-reversible air motor for applications requiring operation in one rotational direction.
• Q: What is the rated free speed of the 3800S?
  A: The manufacturer specifies a free speed of 255 RPM.
• Q: What does the 88 ft-lbs starting torque rating mean?
  A: Starting torque is the torque available as the motor begins rotating the connected load from rest.
• Q: Is 118 ft-lbs the normal continuous operating torque?
  A: No. The 118 ft-lbs value is stall torque, which occurs when the applied load prevents the output shaft from rotating.
• Q: What should be checked before installation?
  A: Verify horsepower, free speed, torque requirements, rotation direction, shaft dimensions, mounting configuration, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog.
