EcoFan is a smart sub floor ventilator used to remove damp, stale air in the sub floor that can cause structural damage, odours and mould growth. 

The EcoFan features an interchangeable exhaust or inward air flow capability. When two EcoFans are installed in the sub floor, the cross flow of air is achieved to allow effective ventilation and improve underfloor air quality problems.

Cross flow ventilation is achieved by setting one EcoFan to exhaust stale, damp air from the underfloor areas into the external environment, and the other to bring fresh, better quality air into a under floor space.

The product has three speed settings that can be set to low, medium or high to suit seasonal variations and specific circumstances in the home. The EcoFan also features humidity sensors that detect the humidity levels and adjust the settings of the EcoFan accordingly to effectively help reduce damp, mould and mildew growth.

Poor quality air in an underfloor area can flow into living areas creating air quality and breathing problems for those living in the home, especially those suffering from asthma and allergies. Therefore, the Edmonds partnership with the Asthma and Respiratory Foundation NZ shows the support for EcoFan providing better quality air for those with breathing problems.
