BROFER BDD Circular Duct Overpressure Damper

BROFER BDD Circular Duct Overpressure Damper is a damper system specially designed for overpressure control in circular duct systems. Equipped with galvanized steel casing, spring loaded aluminum blades and rubber ring fitted inside. Provides superior durability and corrosion resistance with galvanized steel casing structure. Galvanized coating guarantees long-lasting use in various environmental conditions and offers minimum maintenance requirement. Steel casing provides structural strength resistant to high pressures. Spring loaded aluminum blades provide precise pressure adjustment for automatic opening-closing function. Spring system can be calibrated for automatic movement of blades at determined pressure values. Aluminum material offers lightweight structure and corrosion resistance. Rubber ring fitted inside provides excellent sealing and vibration damping property. Rubber ring guarantees complete sealing when damper is in closed position and increases system efficiency. Vibration damping property reduces noise level. Coupling connection system provides easy and safe mounting opportunity to circular duct systems. This connection type offers rapid installation and easy removal process when needed. Coupling system guarantees leak-proof connection. Circular duct overpressure damper feature automatically activates when system pressure exceeds determined limits. This safety feature prevents duct system damages and extends equipment life. Provides system stability with pressure regulation. Spring loaded system offers automatic operation opportunity without requiring electrical control. Provides reliable and maintenance-free operation with mechanical design. Can be adjusted to different pressure values with spring calibration. Overpressure protection provides critical protection in case of fan failures or system imbalances. Controls sudden pressure increases in circular duct system and protects system integrity. Offers continuous protection with automatic working principle. Galvanized steel, aluminum and rubber material combination provides optimal durability, performance and sealing balance. Each material offers best performance in its own feature area. Can be safely used in industrial facilities, commercial buildings, hospitals, school buildings and all HVAC applications requiring circular duct overpressure control. Offers ideal solution especially in round duct systems.
