Solar Whiz provides 3 residential roof ventilators. These are each suited towards particular sizes of homes or rooms! The solar fans we provide are:
The SW-AU-R-15,
The SW-AU-R-28,
The SW-AU-R-40.
Our roof ventilators rely on RAF (Real Air Flow), a measurement system that determines the actual airflow capacity of a roof 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 solar roof fans with all the components attached, not just the power of the solar fan itself.
Our recommendations for ventilating standard pitched homes are based on 10 years of experience in the Australian roof ventilation market. Many of our competitors recommend less capacity. Theoretically, these lower airflow capacity requirements are correct but don’t actually result in the desired outcome – because of severe restrictions for the necessary replacement air.
At GES we carry out our own testing, whilst it appears that our competitors rely on the manufacturers’ specifications. We would encourage anyone considering a competitor to ask them about the test procedure to verify the airflow.
