About VAPOUR VENT Passive Dehumidifier
The VAPOUR VENT passive dehumidifier alleviates condensation and mould by allowing water vapour to pass to the outside whilst restricting draughts and thereby minimising heat loss.
Essentially the VAPOUR VENT compliments a ventilation system by creating a vent point for the moist air (high vapour pressure to low vapour pressure) and by enabling replacement air to enter the property and replenish the extracted air throughout the building.
It is designed to be fitted through an exterior wall and requires a 125mm or 150mm circular aperture.
Features and Benefits
Contains a permeable membrane which encourages moisture migration and provides effective ventilation thereby alleviating condensation and mould
Vapour Vent components are fully recyclable and it operates passively requiring no electrical input.
The membrane restricts draughts so moisture control of the bedroom (or other living areas) is achieved without discomfort to the occupants
Concurrently provides fresh air whilst allowing the vapour to be removed
Provides a relatively cooler surface to attract the moisture away from cold problem areas as well as encouraging air flow by natural convection.
Extracts vapour passively and silently so it is unobtrusive and costs nothing to run
Provides maximum condensation control and benefit when installed as part of a Dryvent solution

Why Passive Ventilation Compliments Extractor Systems
Condensation control extractor fans run continuously and automatically extract at high level to remove moisture that has just been created at source, for example when cooking or bathing. This is when air has the highest humidity and vapour content, and is most likely if not extracted, to migrate to colder parts of a property and condense. By continually extracting air the nascent moisture is removed, but also in effect it creates a vacuum which will suck air in from areas of least resistance, such as through floor boards and through service vents, which usually have high levels of contamination or stagnant air associated with them. Without replacing the air it is also possible to cause undesirable short circuiting of air flow to gas appliances.
Passive ventilation provides a structured solution for air management where the positioning of the vent/s dictates the air movement though the building. The increased movement of air will also have an overall drying effect.
In addition if a Vapour Vent is positioned within a property where the air usually cools and condenses—the problem sites for condensation and mould—this will provide an effective management solution for minimising the cause of these problems.
General Notes on VAPOUR VENT Installations
The Vent position should be at high level and at least the depth of the exterior wall distance from the primary site of the mould and condensation area to the edge of the perimeter of the vent, ie: if the wall is 200mm thick then this must be the minimum distance from the damp area to site the fan

And for the Specifier
The Vapour Vent is supplied with a 125mm diame- ter wall sleeve /150mm diameter push through wall sleeve for safe high level application (an internal va- pour membrane with internal grille (white), external grille (brown), and installation instructions. It should be located on an external wall and in accordance with manufacturers instructions.
