Positive Input Ventilation

Positive input ventilation

Positive Input Ventilation, also known as PIV, is a typical domestic p.i.v. unit placed in a loft space. Equipped with a very efficient fan, it filters clean air into your home using on-board controllers.

It’s basically a small economical fan with a number of speed settings to adapt to properties of differing sizes, levels of occupancy and the severity of the problem.

How does Positive Input Ventilation work ?

The concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. To achieve this, the unit is mounted in the loft space or in the kitchen or hallway, drawing air through the filters and inputting it into the property.

A property installed unit will ensure that old, contaminated air in your home is continuously replaced with good quality, fresh air.
