neverest® RKI 6" Professional Backdraft Damper Inline Spring Loaded

neverest® RKI 6" Professional Backdraft Damper Inline Spring Loaded

• Rear draft flap for insertion into the ventilation pipe DN 150 (6 inches). The RKI return flow regulator opens and closes automatically. It has a strong spring and can be installed both horizontally and vertically. The fin is suitable for retrofitting, as it is completely inside the duct.
• Good sealing and fixing of the duct is achieved by the foam strip attached to the outside of the damper. The rubber cover applied to the damper prevents loud noises when the fins are opened. The fin shell is made of galvanized steel, the fins are made of aluminum, the shaft and spring are made of stainless steel.
• Designed for air conditioning systems, dryers, fans, extractors, heating systems, ventilation systems and other residential, commercial and industrial HVAC applications.
• FUNCTIONALITY: Backflow dampers prevent cold air or wind from entering the ventilation pipe. In this case, the flap is installed in such a way that it only opens in the direction of the air that is coming out. This means that no air / wind (cold) can penetrate the ventilation pipe from the outside.
• INSTALLATION: The backflow valve is installed by pressing it into the vent pipe until it is fixed. The position of the spring should be horizontal when the fin is installed horizontally so that it can be opened and closed optimally. This also applies to vertical installation.
