Exhaust Fans Installation Australia


Installing an exhaust fan for roof ventilation is a great source of ventilation for residential homes and commercial properties. It can sometimes be difficult to find the roof ventilator that’s right for you, but for Australian homes, we’ve found that the Solar Whiz has had some fantastic reviews.

The Solar Whiz exhaust fans are made in Australia, for Australian roofs, Australian homes, and for Australian conditions. The Solar Whiz ventilation system draws hot air out of your roof space and rooms in your home.

Solar Whiz has a wide range of extractor fans for solar cooling including Australia’s most powerful roof extractor fan: the SW-AU-R-40. The number 1 concern for poor roof ventilation is that whirlybirds that are currently installed on Aussie roofs are not removing the air from their roof space. Exhaust fans are beginning to be used in a variety of buildings with applications, both commercial and residential.

Not only does the Solar Whiz extract air from your roof space and home to keep it cool, but it also takes the pressure off your air conditioner and allows it to be much more efficient. We’ve seen up to 20% increases in air conditioner efficiency when it is running with a Solar Whiz installed.

Solar Cooling Solutions with Exhaust Fans

The most efficient and 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 that you use roof cowls for the replacement air.

Replacement air may also be brought in through ceiling vents from the room 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. rooms 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.


Whirlybird Pricing Compared to Solar Exhaust Fans

Whirlybird pricing can vary extensively across Australia – however, a unit like the Solar Whiz exhaust fan can extract a lot more air than your standard whirlybird installation. Anyone who has the ability to install a standard whirlybird will find it easy to install a Solar Whiz exhaust fan unit onto their home. Solar Whiz can even ventilate commercial areas with our commercial exhaust fans. If you have previous experiences with whirlybird installations you may be interested in installing Solar Whiz roof ventilation systems.

The installation of your solar exhaust fan unit can be done by an experienced installer or can be DIY. It’s not uncommon for people to use the instructions and install the units in their own homes. Check out our Solar Whiz dealers if you need an installation done.
