Telescopic valve type 404.05

Telescopic valve

With a telescopic valve you get a complete solution for natural ventilation in your home. A complete telescopic valve with uninsulated wall duct, insect screen, external grey louvre and internal white disc valve.

Used for wall thicknesses from 260-400mm. Can be extended with a 20 cm extension tube.

Note when mounting:
It is best to install telescopic valves in the exterior walls – approximately 150 mm from the ceiling to the center hole. There should be two valves per room, depending on the size of the room. The valves should always be placed opposite each other so that the air circulation runs smoothly. If possible, the valves should be placed on the west and east sides of the house, since the wind in Denmark mainly comes from the west.
