Installing the most suitable sub floor ventilation system in your home can help get rid of air pollutants that can harm your health and your family’s wellbeing. Fresh Ventilation offers efficient solutions that can eradicate stale, moist air in the sub floor area and replace it with cleaner, fresher and drier air. We have three different types of ducted sub floor ventilation systems that you can choose from.
All of our systems are available in any of the three pressure configurations – the components don’t change, the way they are installed determines the configuration.
Depending on how your sub floor ventilation fans are installed, they will either blow air into your sub floor area (positive pressure) or suck air out of your sub floor area (negative pressure). If you have two or more fans installed, it is possible for fans to both blow air in and suck air out of your sub floor area (balanced pressure).
