Telescopic valve type 300

With a telescopic vent, you get a complete solution for natural ventilation in your home. The telescopic vent consists of a wall bushing, an external grey louvre grille, and an internal white diffuser valve. Suitable for wall thicknesses from 230-350 mm. A hole is made in the wall with a slight downward slope, and the telescopic vent is then inserted. It is recommended to seal the external louvre grille with sealant between the wall and the frame.

Note when mounting:
It is best to install telescopic vents in the outer walls - approximately 100 mm from the ceiling. There should be two valves per room, depending on the size of the room. The vents should always be placed opposite each other so that air circulation is smooth. If possible, the vents should be placed on the west and east sides of the house, as the wind in Denmark comes mainly from the west.
