The roof ventilator system is designed to exhaust trapped heat out of the roof space. The room ventilator system is designed to exhaust internal trapped heat out of a hallway into the roof space. Both fans are wired through an adjustable thermostat to turn it on/off at a set temperature.
Hot air is extracted from both the house and the roof cavity so that heat build up during the day is reduced.
Air is sourced from the cooler side of the house, filtered and introduced to each room through diffusers. This not only prevents heat build up during the day but your nights will be more comfortable – allowing you to get better sleep.
