HOW DOES A PIV WORK?

POSITIVE INPUT VENTILATION SYSYEM (PIV)

POSITIVE INPUT VENTILATION SYSYEM (PIV)

  

A Positive Input Ventilation System (PIV) works by gently introducing fresh, filtered air into the dwelling. Air is drawn into the unit and is passed through filters before being pushed around the home

As the air moves, it creates a pressure as it dilutes, displaces and eventually replaces the stale air in the home.

As air is constantly moving, humid air cannot settle on cold surfaces, such as windows or outer walls, meaning it cannot condensate.

Eventually, this humid air is forced out of natural leakage points throughout the home – such as windows, under doors or even through keyholes.


If you live in a flat or have a basement, don`t worry, we can supply and install a PIV system there too!
