Ingersoll Rand 4840D Reversible Multi-Vane Air Motor | 3.3 HP | 9,100 RPM | 5.2 (ft-lbs) Starting Torque | 6.9 (ft-lbs) Stall Torque

Ingersoll Rand 4840D Reversible Multi-Vane Air Motor is designed to deliver dependable pneumatic rotary power for industrial applications requiring high operating speed, reversible operation, and consistent torque performance. Part of the 4800 Series, this air motor provides 3.3 HP with a free speed of 9,100 RPM. Its multi-vane design converts compressed air into smooth, continuous rotary motion, while the reversible configuration allows clockwise and counterclockwise operation for equipment requiring flexible directional control.

The 4840D provides 5.2 ft-lbs starting torque, offering a reference for the torque available to initiate rotation from rest, and 6.9 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. With its combination of horsepower, high rotational speed, and reversible operation, this air motor is suited for OEM machinery, production equipment, rotary drive systems, and other applications requiring reliable compressed-air power.

FAQs:

• Q: Is the Ingersoll Rand 4840D reversible?
  A: Yes. This model is specified as a reversible air motor and can operate in both clockwise and counterclockwise directions.
• 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 rotary motion.
• Q: What is the rated free speed of the 4840D?
  A: The manufacturer specifies a free speed of 9,100 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 produced when the output shaft is prevented from rotating.
• Q: What should be verified before installation?
  A: Confirm horsepower, speed requirements, rotation direction, shaft dimensions, mounting configuration, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
