Clean Fresh Air Continuously

Filtered fresh air is circulated throughout your home day and night. On average most people spend over 80% of their time indoors. 50% of all illnesses are either caused by, or aggravated by poor indoor air quality. The ProAir HRV System will continuously remove stale moist air from your home creating a more suitable and healthy place to live.

Energy Efficient Ventilation

A Heat Recovery Ventilation system will save you money and reduce your energy requirements for heating by re-using the heat that is normally lost through poor construction. A Heat Recovery Ventilation system is also designed to operate continuously at a low rate to minimise the electrical energy consumption.

Condensation Elimination

All water vapour will be removed as it is produced. As a result there is no moisture condensation which causes rot, damp, condensation or mould growth.


Comfort levels are superior in a house fitted with a Heat Recovery Ventilation system/unit. Irrespective of weather conditions, draught free balanced ventilation is provided all the time.
