Back draft damper is made for insertion into inch ventilation ducts. The backflow damper RKI opens and closes automatically. It has a strong spring and can be installed either horizontally or vertically. The flap is suitable for retrofitting, since it is completely inside the 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 installations so that it can open and close optimally.

Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different.
