Solar Extractor Fans For Businesses

Using solar extractor fans, our units pull cooler replacement air in through the eave vents or openings made in your roof space, to replace the warm air extracted out.

Replacement air may also be brought in through ceiling vents from the space below. Normally ceiling vents will only be supplying part of the replacement air, but if a part of the inside of the house is particularly hot (e.g. with windows facing the sun or upstairs rooms) – sometimes all the replacement air may be drawn from these areas – either via a duct or simply through the vacuum created in the roof space by the roof extractor fan.

Roof Extractor Fans Used at Night

In warmer climates, it can be stiflingly hot in your roof space and inside your home after the sun has set. You can continue to use your solar roof extractor fan overnight or when it is dark/overcast during the daytime by adding a night operation system. The solar roof extractor fan can be changed to operate on mains power from a 12-volt power supply when the sun is covered. The roof extraction fan will switch back to solar power automatically when there is sufficient sun on the solar panel for the extractor fan to run. Solar Whiz and the night pack can easily be DIY installed or done by an electrician. The ability to operate the extraction fan at night requires a working powerpoint in the roof or attic space to continue ventilating at night or in overcast weather.
