Solar Whiz provides 3 residential roof ventilators. These are each suited towards particular sizes of homes or rooms! The models we provide are:
  1. The SW-AU-R-15,
  2. The SW-AU-R-25,
  3. The SW-AU-R-40.
Our roof ventilators rely on RAF (Real Air Flow), a measurement system which 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.
