PIV Fan (Intelligent Positive Input Ventilation) Loft Mounted

Overveiw 

The Sano PIV Loft is a loft mounted ultra-quiet, low energy, low maintenance, home ventilation unit. The unit is designed to help ventilate a home using the well-established Positive Input Ventilation (PIV) principle. PIV units have been preventing and curing condensation dampness related problems in homes for decades. They are also used to control other indoor air pollutants and have even proven to be an effective means for reducing Radon gas in some properties.

Application

The Sano PIV Loft is a loft mounted ultra quiet, low energy, low maintenance, home ventilation unit. The unit is designed to help ventilate a home using the well established Positive Input Ventilation (PIV) principle.

Operation

External air is drawn into the loft by the Sano PIV Loft unit. Before it passes through the units filter, the air increases in temperature as it utilises otherwise unused energy in the loft from solar gain and heat loss from the home. This increase can be significant, but is typically around 3℃ warmer than outside air over a heating season. This energy gain is significantly more than the energy used by the units motor. The tempered, filtered air is then supplied centrally to the home via the units outlet duct and ceiling diffuser. Integral controls allow the SANO PIV LOFT unit to be set to suit the individual requirements of the home. Airflow from the unit to the home is automatically regulated via an integral temperature sensor which optimises the energy benefit of the unit while ensuring that sufficient air is always supplied to help control moisture and other pollutant levels in the home.
