The Air Motor is designed to drive the stirrer inside the pressure feed containers. Continuous agitation of the material in the pressure feed container is important in case of heavily pigmented or metallic finishes. Lack of agitation can result in the pigments settling at the bottom of the tank there by giving inconsistency in the color.

The Air Motor operates on compressed air and the output power of the air motor is relative to the speed & to the pressure. It is thus easy to change the speed of the stirrer by throttling the air inlet. The Air Motor slows down when the load increases, at the same time its torque increases to a point where it matches the load. It will continue to provide increased torque all the way to the stalled condition. The motor can maintain the stalled position without any harm to the motor.

The starting torque of an air motor is lower than the running torque, this provides smooth, no shock starting.
