Technical Parameters
Durability Test
50 cycles with no change to the required properties
10000 cycles, actuator controlled (0 … 90 degrees rotation) – with no change to the required properties
10000 cycles, actuator controlled for modular possibility (45 ... 60 degrees rotation) - with no change of the required
properties
Testing Pressure
Under-pressure up to 300 Pa
Safe Position
Closed. (in case of fire the damper closes via a spring in the actuator or a spring in the manual mechanism)
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 a suitable environment
Closing/Opening Time
Manually operated < 10 s, actuator operated < 20 s
Indicator Closed/Open
Manually operated - Activation type H0 visually (arrow on the mechanism) and H2 with microswitches
Actuator operated - built-in microswitches
Activation Temperature for the fire damper closing
Manually operated: 74 °C by means of a spring after the melting of the thermal fuse
Actuator operated: 72 °C by means of a 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 thermofuse (all mechanism types)
Environment suitability
Protected against weather disruptions, with temperature above 0 °C (3K5 according to EN 60721-3-3)
