Description
Gravity shutter intended for ducted ventilation systems, its main function is to prevent the re-entry of air or the entry of atmospheric agents into the duct when the fan is not in operation.
Constructed from durable materials, the shutter features a square design with front dimensions of 546 x 546 mm.
The flaps open automatically when the fan is operating and close by gravity when it is turned off, providing an effective barrier against backflow of air.
