neverest#ad - Backdraft nominal width 100 mm 4 inch exact dimensions see drawing, Galvanized steel housing, Back draught valve for insertion into ventilation pipes, Flap leaves made of aluminum, Axis and spring made of stainless steel, Reduces noise due to internal rubber seal.
Here, the flap is installed so that the damper blades open only in the outflowing air direction. It has a smooth-running spring and should therefore be installed horizontally or vertically only as an exhaust air flap.
This means that no cold air / wind can penetrate from outside through the ventilation duct. Installation: the backflow flap is installed by inserting it into the ventilation pipe until it stops.
Backflow flaps prevent the ingress of cold air or wind through the ventilation pipe. The inner sound insulation strip prevents loud rattling when striking the damper blades. The backflow flap rk opens and closes automatically. The position of the spring should be horizontal for horizontal installation of the flap so that it can open and close optimally. The damper blades open even at low air flow.
