Loft PIV – Improve air quality and stop condensation problems
Did you know?
Our HomeDry Positive Input Ventilation unit (or “PIV unit”) uses air displacement to ventilate a whole dwelling, which improves indoor air quality while at the same time stopping or preventing condensation problems from occurring.
It’s predominantly designed for installation in existing properties and 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, vapour-laden air out via fortuitous air gaps or through humidity window vents.
The ceiling diffuser has been aerodynamically designed to direct incoming air along the ceiling (Coanda effect) where it mixes with warm, buoyant air before re-circulating downwards, thereby ensuring a more even thermal gradient between the floor and ceiling.
Due to its ease of installation, the Homedry PIV Loft Unit is designed primarily for properties that benefit from a well-ventilated loft space.
Features and Benefits

Simple and Easy Installation :
Low Running Costs :
Minimal Maintenance :
Aerodynamically designed diffuser :
A full installation guide is supplied with each system. The ceiling must be as airtight as possible to minimize re-circulation of air from within the dwelling. Roof space must be ventilated from outside, e.g. by eaves vents.
The HomeDry PIV Loft Unit incorporates an extremely low wattage DC motor, minimizing energy usage and should be installed to a fused spur (using a 3 amp fuse).
