A GI Non-Return Damper is a galvanized iron (GI) air control device used in HVAC systems to prevent reverse airflow while allowing one-way ventilation. It enhances system efficiency and air quality by maintaining directional airflow.
A GI Non-Return Damper is an essential component in heating, ventilation, and air conditioning (HVAC) systems designed to allow air to flow in only one direction, preventing backdrafts and maintaining controlled airflow. Made from high-quality galvanized iron (GI), this damper is highly durable, corrosion-resistant, and suitable for commercial, industrial, and residential applications. It operates using lightweight blades or flaps that open when air flows in the desired direction and close when airflow reverses, preventing contamination, dust ingress, and pressure imbalances. Commonly used in ducting systems, exhaust setups, and air handling units, GI Non-Return Dampers improve ventilation efficiency, energy conservation, and system longevity.
