This system is designed to exhaust damp trapped air from the sub floor and introduce fresh air in through existing or new passive vents. This cuts off the source of the moisture from being evaporated through timber floors into the property which helps with mould and mildew issues and protects your timber floors. Xchange air also have second solution (see below) which can be used in conjunction with, or alternatively to, subfloor ventilation fans.
If the roof temperature becomes excessive the unit will switch to standby mode (no airflow). Once installed the airflow can be set to suit the house size and if required the way it responses to the temperature changes within.
We also have another exciting PIV product that in the same way as above it is designed to take fresh air from outside clean the air, warm it (if fitted with heater) and discharge it into the central hallway. The advantage of this system and the way it can be installed is that it’s perfect for Units, Apartments and houses with no roof space.
