Ingersoll Rand 34RB045 Spur Gear Reversible Multi-Vane Air Motor is designed to deliver dependable pneumatic rotary power for industrial applications requiring reversible operation, very low operating speed, and high torque output. This air motor provides 4 HP with a free speed of 121 RPM. Its spur gear and multi-vane configuration provides a pneumatic drive solution for compatible OEM machinery, production equipment, and rotary applications where bidirectional operation and controlled low-speed output are required.
The 34RB045 provides 348 ft-lbs starting torque, offering substantial torque capability for initiating rotation from rest, and 581 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The reversible design allows operation in both rotational directions, while the 121 RPM free speed provides a very low-speed operating option for applications requiring high torque capability.
