Recycles Lost Heat
Warm air rising into the roof from home heating is recovered and recycled back into the house, resulting in much reduced heating costs.
The ventilator forces out the stale moist air that causes problem condensation and damp conditions, replacing it with clean dry air.
Solar Heat Saving
Roof and ceiling spaces are excellent passive collector of solar energy. This warm dry air is supplied back into
the house as the ventilator forces the warmed air into the cooler living spaces.
The outdoor air will be purified before supplied to room for healthy life. Integrated with F9 filter to stop outside air pollutions like PM2.5 into house. Higher air cleanness and cleaner house, save time and money to clean the house.
