EcoFan – Smart Subfloor Ventilation

EcoFan removes damp, humid air from your sub floor to keep your family & your home healthy

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. It is built with Air iQ, which detects the temperature and humidity levels in your sub floor, allowing EcoFan to adjust to the environment. The technology intuitively responds to the conditions in your sub floor and adjusts its fan speed to the optimal setting needed to remove heat and humidity, reducing the risk of condensation, mould and structural damage to your home. 


Effective cross flow ventilation happens when two EcoFans are installed in the sub floor because EcoFan features an interchangeable exhaust or inward air flow capability. For this to happen, one EcoFan can be set to exhaust stale, damp air from the underfloor areas into the external environment, and the other to bring outdoor air into an under-floor space.

Alternatively, EcoFan also has three speed settings that can be set to low, medium or high for continuous ventilation to suit seasonal variations and specific circumstances in the home.


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. Sensitive Choice (National Asthma Council Australia) endorses EcoFan for its ability to provide better quality air for those with breathing problems.
