## Description

neverest® RK 5 inch Backdraft Shutter 125mm Ducting Round Connector Galvanized Steel with Rubber Sealing Fits Only with Metal Ducts

## Features

- Backdraft Nominal width 125 mm (5 inch) (exact dimensions see drawing), Galvanized steel housing, Flap leaves made of aluminum, Axis and spring made of stainless steel, Back draught valve for insertion into ventilation pipes, Reduces noise due to internal rubber seal
- The backflow flap RK opens and closes automatically. It has a smooth-running spring and should therefore be installed horizontally or vertically only as an exhaust air flap.
- The damper blades open even at low air flow. The inner sound insulation strip prevents loud rattling when striking the damper blades.
- Backflow flaps prevent the ingress of cold air or wind through the ventilation pipe. Here, the flap is installed so that the damper blades open only in the outflowing air direction. 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. The position of the spring should be horizontal for horizontal installation of the flap so that it can open and close optimally.
