Telescopic valve type 450 dB
Telescopic valve type 450 dB - natural ventilation that brings fresh air into your home.
With a telescopic valve you get a complete solution for natural ventilation in your home. The telescopic valve is complete with extra soundproof wall duct, insect screen, external grey louvre, internal white wall valve with cord pull, dust filter and condensation-insulated cover.
Used for wall thicknesses from 260-400 mm. Can be extended with a 20 cm extension tube. Sound attenuation in closed position is 62 dB and in fully open position is 47 dB.
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.
