Air
Supply Air
Fresh air is fed directly from outside into the ventilation system through a filter. The heat taken from the extracted air is used to warm the fresh filtered air in the exchanger and then flows through ducting to air vents in the living rooms and bedrooms.
By undercutting doors fresh air circulation is ensured throughout the dwelling. On average, humans spend 90% of their lives in closed buildings. Therefore, it is of prime importance to provide healthier indoor air.
Extract Air
Stale air is contaminated with humidity, toxins and smells extracted from the kitchen, bathroom and toilet.
Outlet vents in toilets and wet room areas, such as the bathroom, en-suite, utility and kitchen allow a constant air flow volume to be extracted, matched to the user’s individual needs or room’s demands.
Much of the heat of the extracted air is retained by the heat exchanger and transferred to the incoming fresh external air.
