What is a Positive Input Ventilation (PIV) System?

Suitable for new builds & existing properties and apartments, this condensation control unit ventilates buildings by bringing filtered air in through a central location.

How a PIV System Works

The PIV unit draws fresh filtered air into the building and gently ventilates from a central position on the landing or central hallway. Stale, moisture-laden air is diluted, displaced and replaced with subtle fresh filtered air forcing contaminants out of the property through leakages or extract points in wet rooms (if applicable).

Benefits of Positive Input Ventilation

Clean indoor air moving through building

Improved indoor air quality

A PIV System constantly supplies clean, fresh, filtered air into the property, so there is no need to open windows which often allow dust and other pollutants inside.

Warm air within properties accumulates at ceiling level, this air can be up to 7°C higher than the air at floor level. The PIV unit helps to redistribute this heat around the home and thus reduce space heating costs.
