The Fire Flap FS-36 is a specially engineered fire safety component designed to prevent the spread of fire and smoke through ventilation ducts, cable trays, or wall openings. Installed as a passive fire protection device, the FS-36 activates automatically in the event of a fire, sealing off the passage and helping to maintain the integrity of fire-rated compartments. Its robust construction and reliable mechanism make it an essential feature in modern fire protection systems.

The FS-36 Fire Flap is constructed from fire-resistant materials, typically galvanized steel or stainless steel, and includes an intumescent lining that expands when exposed to high temperatures. This expansion seals the gap and restricts the movement of hot gases, flames, and smoke. The flap can be either manually or thermally operated and is designed to close automatically at a preset temperature (usually around 70°C to 74°C). It is compact in design, easy to install, and requires minimal maintenance, making it ideal for long-term fire protection.

Widely used in commercial buildings, industrial plants, data centers, hospitals, and multi-story residential structures, the FS-36 Fire Flap is installed in HVAC ducts, risers, and cable shafts to ensure that fire does not breach protected areas. By effectively containing fire within designated zones, it supports compartmentalization strategies and enhances the overall performance of fire suppression systems. The FS-36 plays a crucial role in fire safety compliance and building code requirements.
