Easy to install and maintenance-free, the Perma-Vent Condensation Control Vent is a quick and easy way to reduce, if not stop, condensation in localised areas.
Passive Ventilation Unit
The environmentally friendly Perma-Vent contains no moving parts and requires no maintenance. It works on the scientific principle that when the room temperature and humidity are greater internally than externally, moist air will be ventilated outside the building due to vapour air differences.
The Perma-Vent contains a vapour permeable membrane, which allows vapour out of the building without allowing a draught back inside.
Installing a Perma-Vent unit
The unit is easily and economically installed using a 4.25” (107mm) core cutter. It can be positioned wherever condensation and mould are most prevalent. The thickness of the wall does not present a problem as the standard unit is supplied with a 13.5" (350mm) long central core which will be suitable for most properties.
The unit is designed to be very unobtrusive, with a 6" (152mm) internal white plastic grill. Externally all that can be seen is a 6" white plastic external grille.
It is possible in severe instances that a more advanced condensation control unit will be required to remedy issues with condensation. However, the installation of a Perma-Vent Standard is a simple, inexpensive starting point to tackle the local problems of condensation and mould.
The external diameter of the tube is 104mm so the core should be cut larger eg. 4.25” (107mm).

What size core drill do I need to install a Perma-Vent passive vent?
You will require a 107mm core drill, and you should drill at a slight downwards angle towards the external face to stop any water ingress.
Can the Perma-Vent be used in a kitchen?
Yes, the Perma-Vent can be used in a kitchen for background ventilation. However, where there is prevalent mould or condensation, you should always consider the reason for the moisture (cooking). You should also consider the amount of moisture released per minute which in kitchens is high. In this scenario, it would be beneficial to consider an extractor fan or Heat Recovery Unit as they are designed to handle large volumes of air and moisture in a very short period of time. They will remove damp air before it even gets a chance to condense on the cold surface and stop this air from moving to other parts of the property and causing issues elsewhere.
