6/59 | F-R60K
Technical Parameters
Durability Test
10000 cycles, actuator controlled (0 … 90 degrees rotation) – with no change of the required properties
10000 cycles, actuator controlled for modular possibility (45 ... 60 degrees rotation) - with no change of the required
properties
Testing Pressure
Underpressure up to 300 Pa
Safe Position
Closed. (In case of fire the damper closes via a spring in the actuator )
Airflow Direction
Both directions
Allowed Air Velocity
Damper can still operate at max. 12 m/s. Air without any mechanical or chemical contamination
Side with Fire Protection
Depending on installation classification: From both sides (i <-> o)
Repeated Opening
Suitable for daily check procedure in suitable environment
Closing/Opening Time
Actuator operated < 20 s
Indicator Closed/Open
Actuator operated - built-in microswitches
Activation Temperature of the Fire Damper Closing
Actuator operated: 72 °C by means of the spring after current interruption in the electro-thermal fuse
Temperature of Transported Air
Minimum: 0 °C, for all types of mechanism
Maximum: 60 °C for 74 °C and 72 °C thermal fuse (All mechanism types)
Environment Suitability
Protected against weather disruptions, with temperature above 0 °C (3K5 according to EN 60721-3-3)
Inspection Possibility
Inspection of blade and gaskets can be done through electro thermal fuse hole with endoscopic camera. To have the
possibility to access the damper internals a flexible connection or duct with access doors must be connected to the
damper.
