Solar Roof Exhaust Fans for Your Home

The simplest and most cost effective way to remove warm air from the home is by installing a solar roof ventilation extractor fan to remove heat from your roof space – i.e roof exhaust fans through roof ventilation. Solar Whiz has a wide range of extractor fans for solar cooling including Australia’s most powerful roof extractor fan: the SW-RAF21000.

We have the perfect house cooling solutions for a wide range of applications, in addition to commercial exhaust fans.

Solar Cooling Solutions with Exhaust Fans

The most economical cooling solution for your home is to install a solar heat extraction fan.

Roof exhaust fans are most commonly mounted on the roof. However, Solar Whiz also has a range of Gable Mounted heat extractor fans, if it isn’t practical or desirable to mount the extractor fan on the roof to obtain the required house cooling effect.

When cooling your roof using a roof extractor fan, the roof exhaust fan extracts warm air from the roof space and cooler replacement air is pulled in – normally through eave vents – or other openings  in the roof space. If your home doesn’t have any eaves – we recommend to use roof cowls for the replacement air.

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) – 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.

Please refer to our roof ventilation and home ventilation animations, which clearly demonstrate the operation of the Solar Whiz extractor fan.

What about Ventilation for Commercial Properties?

While we provide powerful solar roof ventilation solutions for your home, we also have a commercial ventilation line! We’ve designed them to properly ventilate the extreme heat that large-scale properties can produce. On top of that, our commercial exhaust fans are excellent at adequately ventilating fumes for industrial businesses. Our solar commercial ventilators come in two sizes:

 the SW-RAF7000, capable of moving 7,000 m3/h (cubic metres of air),
and the SW-RAF10000, capable of moving a whopping 10,000 m3/h!

If you’re thinking of buying cheap whirlybirds to help ventilate your business, consider a Solar Whiz instead! You’ll be feeling the difference during those hot summer days.
