The STPIVLH Positive Input Ventilation unit from Tornado creates fresh and healthy living environments by supplying filtered air into a property from your loft space at a continuous rate through a ceiling-mounted diffuser. The units have been developed to improve indoor air quality and resolve condensation and mould problems.
When the loft air temperature drops below 10°C, the internal heating element turns on to temper the incoming air. Once the loft air rises above 10°C, the heating element turns off. You can install the optional remote hardwired heater control switch, which allows you to disable/enable the automatic heater function.
In conditions between 19°C - 25°C, the units will increase the air flow rate by 10%. In hot conditions above 25°C, the units will temporarily switch off to avoid bringing hot air into the property from the loft space.
The PIV Unit uses a single 200mm diffuser to provide air into a hallway or landing area, which is supplied with the unit, along with all items required for installation.
