Ingersoll Rand 4800P Multi-Vane Non-Reversible Air Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring high horsepower, controlled operating speed, and exceptional torque output. Part of the 4800 Series, this air motor delivers 3.5 HP with a free speed of 510 RPM. Its multi-vane design converts compressed air into smooth, continuous rotary motion, while the non-reversible configuration provides reliable single-direction operation for compatible industrial equipment.
The 4800P provides 98 ft-lbs starting torque, offering substantial breakaway force to initiate rotation under heavy loads, and 131 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. With its combination of horsepower, low operating speed, and high torque capability, this air motor is suited for OEM machinery, industrial processing equipment, material handling systems, and other applications requiring reliable compressed-air rotary power.

FAQs:
- Q: Is the Ingersoll Rand 4800P reversible?
A: No. This model is specified as a non-reversible air motor designed for 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 rotary motion. - Q: What is the rated free speed of the 4800P?
A: The manufacturer specifies a free speed of 510 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.
