Vent Axia PureAir 479090 Positive Input Ventilation System PIV

This loft mounted input fan draws fresh air from the outside atmosphere, filters it and pushes into the dwelling via a ceiling mounted diffuser. All stale air in the property is forced out through the natural forms of ventilation or trickle vents.

The robust construction of the PureAir features a specially developed LoWatt DC fan motor which gives incredibly low running costs. The special insulation mount ensures that it is extremely quiet in operation. It may be used for air replacement in conjunction with exisitng extractor fans. 

The unit includes a filter with up to 5 years maintenance intervals to reduce the number of call outs needed throughout its life span. The unit features a time elapsed meter to enable precise running information. With selection of 2 of 6 speeds available up to 50l/s, the unit is suitable for houses up to 360m3.

The PureAir uses a sensor to monitor the temperature in the loft, automatically adjusting the air volume when necessary. 'Trickle' speed is automatically selected when the ambient loft temperature is up to 18°C. 'Normal' is automatically selected when the ambient loft temperature is between 18 and 27°C. If the ambient loft temperature exceeds 27°C, the PoziDry will automatically switch to standby (no airflow). 

Simply install, out of sight in the loft space, either suspended from a roof beam or floor mounted. It has a purpose designed diffuser, normally located over the stairwell of a conventional two story dwelling or in the main hall of a bungalow. It is set to the appropriate speed at installation based on the size of the dwelling, providing positive pressure input ventilation. Background ventilation openings provide the exhaust points.
