What is non return damper?

Non-return dampers open and close automatically. When the system is in operation, the blades open when air flows. When the system is shut down, the blades close due to their weight. They safely prevent air from flowing against the intended airflow direction.

What is a butterfly damper used for?

Butterfly dampers are used to restrict the flow of materials in ducting systems where flow control and low leakage isolation are a priority. These dampers are especially useful in applications such as incinerators, balancing systems, control air systems, stack isolation, and scrubber systems.

How does a gravity damper work?

Backdraft dampers (also known as gravity dampers) are used in ventilation systems to allow airflow in one direction and prevent airflow in the opposite direction. A relief damper is developed with an elevated and adjustable start-open pressure while providing the backdraft function.

What is backdraft damper?

Backdraft dampers allow air to efficiently flow through exhaust ducts to the outside, yet prevent the unwanted flow of air into a house when the exhaust fans are off. They stop cold air from coming in, allowing a more comfortable temperature in your home.

What is backdraft damper used for?

What is an isolation damper?

Isolation dampers are manufactured for effective shut-off and isolation of one or more tiers of filters in a hazardous-duty containment exhaust system. The bubble-tight isolation dampers are our top-of-the-line dampers.

What are types of dampers?

Dampers can also be classified based on their application, and the following are some of the main types:

• Balancing dampers (volume dampers)
• Face and bypass dampers.
• Fire dampers.
• Smoke dampers.
• Combined fire and smoke dampers.
• Gravity dampers (backdraft or barometric)
• Mixing dampers.
• Multi-zone dampers.
