Features
 

• Mode of operation  The actuator moves the damper to its normal working position while tensioning the return spring at the same time. If the power supply is interrupted, the energy stored in the spring moves the damper back to its safe position.

• Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp. An antirotation device is supplied to prevent unwanted rotation of the whole unit.


• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
