High-Integrity Slip-In Fire Dampers Misty Ref Plain Type Fire Dampers are engineered for reliability in extreme conditions. Constructed from heavy-duty galvanized steel, these dampers feature a curtain-style blade system held open by a UL-listed fusible link. When the air temperature reaches a critical point (typically 74°C or 165°F), the link melts, and the blades drop instantly to seal the duct.
Key Technical Features:
Curtain Blade Design: Interlocking blades are gathered at the top of the frame for maximum free area and minimal air resistance during normal operation.
Fusible Link: Precision-calibrated links ensure the damper closes exactly when needed.
Rigid C-Channel Frame: The 1.2mm to 1.5mm GI frame is designed to remain square and operational even under the thermal stress of a fire.
Sleeve Installation: Can be factory-fitted into a wall sleeve for a “ready-to-install” solution that meets local building codes.
