What is Backdraft Shutter Damper Connector Duck?

Backdraft Shutter Damper and Connector Duct are two different components used in ventilation systems.

1. Backdraft Shutter Damper: It is a device used to prevent the reverse flow of airflow in a ventilation system. It is usually installed in locations where airflow needs to flow in a specific direction, such as exhaust fans, range hoods, bathroom exhaust fans, or air conditioning systems.

When the airflow flows in the expected direction, the reverse blocking valve will open, allowing air to pass through. When there is a reverse airflow or no airflow, it will close to prevent the airflow from entering in the opposite direction.

This type of equipment is crucial for maintaining the efficiency of the ventilation system, preventing air pollution, and ensuring correct exhaust or ventilation in various applications.

2. Connector Duct: A connector duct is a duct used to connect different components or parts of a ventilation system. It is used to ensure tight connections between these components, enabling smooth air transfer.

Connector ducts are typically used to connect various components, such as connecting exhaust fans to outdoor vents or connecting two duct sections together. It can ensure safe and secure connections, achieving smooth airflow transmission between components.

Reverse flow blocking valves and connector ducts are usually used together to ensure the desired airflow direction and prevent the occurrence of reverse airflow. This is crucial for maintaining the efficiency of ventilation systems, preventing air pollution, and ensuring proper exhaust or ventilation in various applications.
