4AM-NRV-22F Rotary Vane Blade Air motor

 Vane air motor vane pneumatic motor

Working Principle:

4AM-NRV-22F vane air motor is a kind of energy conversing device, which adopts compressed air to rotate vanes, changing air pressure energy into mechanical energy and outputting driving power.

Application places: 

Widely used in mining, oilfields, constructions, smelting, paper making, pharmacy, chemicals, etc,. this motor is ideal mated driving machine for large-scale drilling machines.



1. Step less in speed, adjusting air volume to change rotate speed and power. 

2. Change air-inlet and air-outlet direction to rotate and counter-rotate the motor in short time, with no impact and even not need to relieve the load. 

3. the equipped anti-load function enables the motor to rotate at low speed when overload, and regain high speed when overload relived. 

4. Stable under inflammable, explosive, outdoor, wet, damp and other extremely conditions. 

5. Concise structure, compact in size and light in weight, easy to operate and convenient to maintain. 

6. High starting torque enables starting with load, fast and reliable to start and stall.
