Air Clutches

Twin Disc Air Clutches do not require adjustment for friction plate wear. Further, air clutches exert more torque for a given diameter because of the large air diaphragm providing the clamping force. But air clutches are not uniformly used because of the difficulty of providing air to many installations.

Air clutches have the further advantage of being easily remote controlled. They can be readily tied into the machine cycle with push button control, automatic actuation through limit switches, or other devices of this nature. Control valves are of two general types. When sudden rapid engagement is permissible, a simple "on-off" valve can be used. Where smooth engagement or partial torques are required, a controlled pressure valve is selected. The pressure admitted through this type is proportional to the throw of the control lever.
