• The folding valve opens and closes automatically and allows only one air flow in one direction, block cold air into the pipe. When the blind is mounted, the flap leaves open only in the direction of the outflowing air. The shaft axle must be vertical when installing the backflow flap and best installed in a horizontal position and inserted completely into the pipe. This also applies to vertical installation
• The casing of the flap is made of galvanised sheet steel. The valve blades are made of aluminium. Shaft and spring are made of stainless steel
• The inner rubber seal is used for better tightness and noise reduction. The outer foam sealing strip ensures a good seal and fixation of the backflow flap in the channel. The flap valve can be inserted directly into a non-flexible metal or plastic duct, but for a flexible duct, you will need to use steel pipe clamps to secure the check valve
