Our Range of Commercial Extractor Fans

Want to learn more about our products & how they work?

Solar Whiz offers the SW-AU-C-155 as our Commercial Extractor Fans.

Our roof ventilators rely on RAF (Real Air Flow), a measurement system that determines the actual airflow capacity of a ventilator. Many roof whirlybirds and ventilators only state their Theoretical Capacity (TC), such as a standard roof whirlybird providing near to 100m³/h under optimal conditions. We test our units with all the components attached, not just the power of the fan itself.

Commercial ventilation is essential for keeping staff comfortable & productive. More importantly, unventilated workplaces can lead to stock damage or loss—think of fruit packing or livestock!

It’s important to take your industrial ventilation seriously. In a standard warehouse, temperatures can easily reach as high as 40°C to 50°C in Summer. This heat doesn’t go anywhere if you can’t extract it! Many businesses turn to industrial whirlybirds, only to find their performance underwhelming.

A Solar Whiz unit is one of the most powerful commercial roof ventilators on the market. On top of heat management, Solar Whiz assists with:

  1. Moisture extraction
  2. Mould & fungi prevention
  3. Air conditioning improvement
  4. Exhaust control (for steam or smoke)
