PIV Home Ventilation Unit
The Home Dry Positive Input Ventilation unit (or “PIV unit”) uses air displacement to ventilate a whole dwelling, improving indoor air quality and stopping or preventing condensation problems from occurring. Perfect for retrofit installation into existing properties, the HomeDry PIV Loft Unit is very easy to install.
A single fan unit mounted in the roof space supplies fresh, filtered air into the dwelling via a central hallway or landing. This creates a slight positive air pressure which forces stale, moisture-laden air out via sundry air gaps and natural leakage.
