A Backdraft Dampers is a safety device used to prevent reverse airflow in ventilation systems, ensuring that air flows in the correct direction.
Backdraft Dampers
Block reverse airflow for safe, efficient ventilation
We are a leading manufacturer of Backdraft Dampers in Mumbai, India, specializing in providing reliable solutions to prevent reverse airflow in ventilation and exhaust systems. A Backdraft Damper is a vital component designed to allow air to flow in one direction while blocking any potential backflow in the opposite direction. These dampers play an essential role in protecting systems from reverse airflow, which can lead to contamination, equipment damage, or loss of energy efficiency.
The damper operates with a set of hinged flaps or blades that automatically open to allow airflow in the intended direction and close when airflow reverses. This self-acting mechanism ensures the system remains protected at all times. Backdraft dampers are widely used in HVAC systems, industrial exhaust systems, and fire/smoke control applications. Made from materials like stainless steel or galvanized steel, they are built to withstand challenging environments. These dampers are a key part of maintaining safety, system performance, and energy efficiency in both residential and industrial settings.
