ASLI Multi-Blade Fire Dampers have been developed to provide the versatility required for today’s complex and sophisticated fire protection and safety building system. There are two types of fire dampers: Fire damper with fusible link (FSD60) and motorized fire damper (MFSD60).
Frame: Galvanized steel, 1.5mm thickness.
Blade : Galvanized steel, 1.5mm thickness.
Jamb seal: Stainless steel plate, compression type.
Blade seal: Silicone strip. (Optional)
Bearing
Bronze bush pressed into frame.
Axles
Hexagon bar mild steel.
Blade Actions
FSD60: Parallel type
MFSD60: Parallel type
Blade Dimension Limits
Maximum blade length = 1000mm
Maximum blade width = 160mm
Fire Damper (FSD60)
During fire, the FSD60 provides the quick closure respone by means of tentioned spiral spring mounted at the side when the fusible link fuses at 74°C (165°F).
Motorized Fire Damper (MFSD60)
During fire, a signal will be sent from sensor or control unit to the actuator of MFSD60 Upon receiving the signal, MFSD60 will be closed by means of actuator.
MFSD60-1T: Actuator mounted exposed at the side of the fire damper.
MFSD60-2T: Actuator mounted in a compartment at the corner of the fire damper.
MFSD60-3T: Actuator mounted in a compartment at the side of the fire damper.
MFSD60-4T: Actuator mounted in an extrusion fitting.
