Smart-Vent Positive Pressure Ventilation

Positive Pressure systems draw fresh drier air from the roof space and passes it through a filter before gently distributing it around the home via diffusers set in the ceiling at strategic points.

The introduced air positively pressurises the home and displaces moist air generated by human activities such as washing and cooking. The end result is a drier living environment, less prone to condensation and virtually free of airborne contaminants. The system incorporates a supply airflow under pressure, therefore getting it’s name ‘positive pressure’.

Smart-Vent systems work off a comfort temperature range (a minimum and maximum temperature that you would like your home to be), set by yourself on your digital controller. The temperature is read from your roof space where the supply air is drawn from. As soon as this temperature falls below or rises above your comfort temperature range (e.g. minimum of 16°C and maximum of 22°C) then the system will automatically react to restore your desired comfort temperature range. This could be turning on your heater (optional extra), dropping to a low fan speed when too cold, or drawing air from outside (when a summer feature is installed) in the warmer summer months.

Filter Grading
The filter is a main component of a ventilation system which contributes towards a better indoor environment. Everyday on average we breathe 20-30kg of air which is why it is essential to filter atmospheric particles that can adversely affect our health. This air can contain household dust, moulds, fungi, pollen and vapour residue.

G4 grade sock filter: Over its life the filter will, as an average, have a 90% arrestance of particles of 5 microns in size and above.

High quality F7 grade induct filters: Over its life the filter will, as an average, have an 80-90% arrestance on particles 0.4 microns in size and above.
