Product description ------------------- 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. 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 ventral core which will accommodate 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).
