Ingersoll Rand 3840P Multi-Vane Reversible Air Motor | Series 3840 | 1.35 HP | 440 RPM | 40 (ft-lbs) Starting Torque | 53.5 (ft-lbs) Stall Torque

Ingersoll Rand 3840P Multi-Vane Reversible Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring increased output torque, controlled operating speeds, and bidirectional operation. Part of the 3840 Series, this air motor delivers 1.35 HP with a free speed of 440 RPM. Its durable multi-vane design converts compressed air into smooth, continuous rotary motion, while the reversible configuration allows both clockwise and counterclockwise operation for equipment requiring flexible directional control.

The 3840P develops 40 ft-lbs starting torque, providing substantial breakaway force to initiate rotation under load, and 53.5 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. This combination of controlled speed, dependable horsepower, and reversible operation makes the motor well suited for OEM machinery, indexing systems, conveyors, processing equipment, material handling systems, and other compressed-air powered industrial applications.

FAQs:

• Q: Is the Ingersoll Rand 3840P reversible?
  A: Yes. This model is designed to operate in both clockwise and counterclockwise directions for applications requiring bidirectional shaft rotation.
• 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 440 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.
