Is your home turning into an oven every summer? Roof cavities can reach 70°C on a hot Australian day — and that heat radiates straight down into your living space, forcing your air conditioner to work harder. The Solar Whiz SW AU 28 stops the heat at the source, for free. How it works The SW AU 28 RAF (Real Air Flow) actively extracts hot air from your roof cavity during daylight hours. It replaces that hot air with cooler ambient air drawn in through eaves vents — reducing ceiling temperatures and the radiant heat load on your home below.

The SW AU 28 moves 1,700m³/h every hour , powered by the same sun that's heating your roof.
