Our Backdraft Damper is a reliable and efficient solution designed to prevent the reverse flow of air in circular duct systems. Constructed with galvanized steel, this damper offers exceptional durability and corrosion resistance, ensuring long-lasting performance. The Backdraft shutter features blades made of lightweight and durable aluminium. These aluminium closure flaps are designed with a split flap closure and a spring gear mechanism, allowing airflow to pass in one direction while effectively blocking reverse airflow. The flaps open during overpressure conditions and close automatically via the spring when the pressure drops, ensuring optimal airflow control. Designed for easy installation, our non return valve is compatible with all types of round ducts. Its versatile mounting capability allows for horizontal positioning, making it suitable for a variety of applications. Whether it's a residential, commercial, or industrial setting, this damper seamlessly integrates into your ventilation system, providing reliable performance. To ensure a quiet and efficient operation, the Backdraft Damper is equipped with an inner foam seal. This foam seal not only enhances the tightness of the damper, reducing air leakage, but also helps minimize operating noise. Enjoy a more peaceful and comfortable environment without compromising on airflow control.
