Planox® Safety Clutches for Extruder Drives

Planox® clutch type PPF - RA
with flexible Ox-coupling

This Planox® clutch type PPF - RA is a pneumatically engageable dry plate friction clutch. The clutch is engaged by air pressure. When the air pressure drops the clutch is completely disengaged and no remaining torque can be transmitted as the pressure springs ensure that the pressure plates are separated. The compressed air is fed into the clutch trough the gearbox shaft.

Planox® clutch type PPRF
with flexible Ox-coupling

This combination differs only in the design of the Planox® clutch. With the Planox® type PPRF the compressed air is fed in radial direction from outside into the cylinder of the clutch. With this design, long shafts do not have to be bored to allow air passage to activate the clutch.
