Product Information

Back Draught Duct Shutters are a ventilation system accessory that includes spring-operated flaps, which are designed to prevent the backflow of air when the fans are turned off. The flaps are made from aluminum and are housed in a galvanized sheet steel housing.

When the fans are turned on, they create a positive air movement, which causes the flaps to open, allowing air to flow through the ventilation system. The flaps are spring-operated, which means that they are held in the open position by a spring mechanism.

When the fans are turned off, the positive air movement stops, and the spring-operated flaps automatically close. This prevents any backflow of air from the ventilation system, which could potentially bring contaminants or odors back into the ventilated space.

The housing for the flaps is made from galvanized sheet steel, which is a strong and durable material that is resistant to rust and corrosion. This helps to ensure that the flaps are protected from damage and can operate effectively over an extended period of time.

The flaps themselves are made from aluminum, which is a lightweight, yet strong and durable material. Aluminum is also resistant to corrosion, which helps to ensure that the flaps remain effective at preventing backflow over the life of the ventilation system.

Overall, the spring-operated flaps are an important component of a ventilation system, as they help to ensure that air flows in the right direction and that the quality of the air in the ventilated space is maintained. The galvanized sheet steel housing and aluminum flaps are designed to be strong, durable, and corrosion-resistant, which helps to ensure that the ventilation system operates effectively over an extended period of time.
