The InvaVent Mechanical Extract Ventilation systems are predominantly used in dwellings and apartments with five wet rooms or less (dwellings up to 300m² / 3200 sq ft). The sleek compact mechanical extraction ventilation unit is generally installed in the roof space and ducted to all wet rooms. The low energy unit runs at a low ventilation rate continuously extracting stale polluted air from rooms where the most moisture is generated e.g. kitchens and bathrooms.
Fresh air is normally provided from outside to habitable rooms by trickle ventilators fitted on windows, creating a flow of clean fresh air throughout the dwelling. The extract air is ducted from “wet rooms” to the outside and the extract rate is normally boosted at times when excessive moisture is being generated, such as when cooking or bathing.
