Fire dampers represent passive fire protection, designed with the help of compartmentalization to prevent the spread of toxic gases, smoke and fire. All our standard fire dampers are designed and certified in accordance with the test criteria’s EIS according to EN 1366 – 2. Fire damper together with its installation form an inseparable part of fire resistivity rating. Their installation is described in the User Manual of the fire dampers. Their installation is described in the User Manual of the fire dampers. The activation mechanisms are removable and all are interchangeable, for example an actuator mechanism instead of a manual mechanism.

• Lightweight construction • Exchangeable mechanism • Easy and quick installation via installation kit (accessory) • Manual mechanism with IP44 rating

The product contains galvanized sheet metal, calciumsilicate board, fireproof carbon fiberglass, polyurethanwe foam and ethylene - propylene rubber. These are processed in accordance with local regulations. The product contains no hazardous substances, with the exception of the solder in the thermofuse, which contains a milligram of lead.

All circular fire dampers have tightness of the blade/casing class 3C according to EN 1751.

By default, all manually operated fire dampers are supplied with manual control, optionally with micro switches and electromagnets. In case of fire, the fire damper is closed automatically. Depending on the version, the damper closes either after melting of the thermal fuse or by means of remote activation through electromagnet in impulse connection. After the closing of the damper blade, it is mechanically locked in the closed position and can only be opened manually. Actuating mechanism is activated when the temperature of the air in the duct reaches 72°C and the damper closes within 10 seconds after melting of the fuse.

• ZV Fire damper with an activation mechanism with a cover, manual crank and with a spring return release mechanism activated by a fusible thermal link set to 72°C (on demand 100°C). • DV1-2 Fire damper with an activation mechanism ZV + open and closed indication with 230 V/24 V contact switches. • DV5-2 Fire damper with an activation mechanism ZV + a 24 V AC electromagnetic release mechanism in the impulse connection (release takes place when the electromagnet is activated)

By default, all actuator operated fire dampers are supplied with actuator with micro switches, optionally with power and communication unit. Fire damper can be equipped with a spring return actuator which closes the damper after the command from the building management system, or after breaching of the thermoelectric fuse. Actuator controlled fire dampers are standardly equipped with thermoelectric fuse, that activates the closing of the damper after reaching or exceeding of ambient temperature of 72°C. Actuator power circuit is interrupted and its spring closes the damper blade within 20 seconds.

• DV7-T or G7-T Fire damper with an activation mechanism with a Belimo (DV) or Gruner (G) spring return actuator (230 V AC) with an electro-thermal fuse 72°C and auxiliary switches. • DV9-T or G9-T Fire damper with an activation mechanism with a Belimo (DV) or Gruner (G) spring return actuator (24 V) with electro-thermal fuse 72°C and auxiliary switches. • DV9-T-ST or G9-T-ST Fire damper with an activation mechanism with a Belimo (DV) or Gruner (G) spring return actuator (24 V) with an electro-thermal fuse 72°C and auxiliary switches, with a Belimo supply and communication unit BKN230-24 or Gruner supply and communication unit fs-UFC24-2 (other communication units on demand). • DV9-T-W or G9-T-W Fire damper with an activation mechanism with a Belimo (DV) or Gruner (G) spring return actuator (24 V) with an electro-thermal fuse 72°C and auxiliary switches, with provided cable connectors for the supply and communication unit (communication unit not part of the mechanism). • DV9-T-SR or G9-T-SR Fire damper with an activation mechanism with a Belimo (DV) or Gruner (G) spring return actuator (24 V) with electro-thermal fuse 72°C and auxiliary switches for Modulated dampers (possibility to open the blade at the desired angle). For fire dampers in the size DN ≥ 160 mm or H ≥ 160 mm.
