Detailed Product Description:

Vane Air Motor


Application places: 

Widely applied in mine, oil field, construction, metallurgy, paper making, medicine, chemical industry, smelting

and other industried, as the power facility of some large-scale equipment like rock drilling machinery, etc.



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.
