Airflex CTE drum style brakes are spring-applied, air released and develops greater torque than Type CS. Its design and construction are ideal for moderate speed, high torque, cyclic applications. The brake is bi-directional, developing approximately the same torque in either direction of drum rotation.

Airflex CS drum style brakes are spring-applied and air released. It automatically engages should an air or electrical loss of power occur. The brake is unidirectional, developing less torque in the reverse direction of drum rotation.
