Extendable Type
Passive dehumidifier to increase room ventilation, helps prevent black mould.
For increasing room ventilation. Suitable for most wall thicknesses.
The Passive Vapour Vent MK2 contains a permeable membrane within the main plastic circular tube. This encourages moisture migration due the differences between external and internal temperature and air pressure. The membrane acts as a molecular sieve, allowing water vapour to pass to the outside whilst resisting rapid air movement and therefore heat loss. The vent is also fitted with a specially designed cowl which counteracts the detrimental effects of external wind on performance.
