Blauberg BSK1 160 1A
- Designation key
A fire safety damper prevents the spread of smoke and fire via ventilation and air conditioning system ducts in the event of fire.Such units are installed in air ducts located in fire-separation walls and ceilings. The fire resistance rating according to EN 1366-2 is EIS 60 or EIS 120.
The BSK series dampers are made in the general-purpose industrial version with a minimized variety of hardware components using lowalloy galvanized steel. The flap is made of fire-resistant material (vermiculite) with thermoexpansive fireproof sealing. The duct design implies two connection ports for integration into a ventilation duct (duct system).
|CONTROL AND MODIFICATIONS
Depending on the design variant the BSK series dampers are equipped with:
MECHANICAL ACTUATING UNIT WITH A THERMAL FUSE AND A RETURN SPRING The fire safety damper remains open in the protective position. The damper is set to the operating position upon the thermal fuse breakdown resulting from a temperature increase. In the event of fire, the fusible element will melt upon the temperature reaching 72 °C and the spring will set the flap to the closed position.THE BSK...1A FIRE SAFETY DAMPER WITH A MECHANICAL ACTUATING UNIT, A THERMAL FUSE AND A RETURN SPRING
During the fire safety damper installation make sure that the release mechanism and the inspection hole face an easily accessible side of the wall or ceiling. This will ensure convenient control of the thermally sensitive release mechanism and its internals. The damper can be embedded into brick or concrete walls with the appropriate fire resistance rating. Wooden spreader bars should be used to avoid casing deformation during the installation.
Upon completing the installation remove the wooden spreader bars.
The damper may not be installed:
