Joventa SFR / SFL – Spring Return Electric Actuator

Joventa SFR / SFL spring return electric actuator with right or left rotation with 90 or 180 deg angle of rotation. It is equipped with spring return feature for fail-safe operation of fire, smoke dampers, in case of power failure, fire conditions.


Joventa SFR / SFL – Spring Return / Fail Safe Fire Actuator

Security fire, spring return or fail-safe electric actuator Joventa SFR or SFL series has specially designed developed for motorised operation of safety dampers, like fire dampers, fire smoke damper, smoke dampers.

When control signal is applied, actuator drives the damper to operational position, while evenly tensioning the integrated spring. In case of power failure, like smoke or fire incidence, the store energy in the spring immediately bring the damper to the safety position. Actuator has manual and automatic operation facility.
