With nine models in the SAV range, choosing the right ventilator comes down to three things: your roof size, your roof pitch, and which way it faces.
Size and pitch
As a rule of thumb, a 100 m² roof is well served by a single SAV-10B, while larger or steeper roofs step up to the SAV-20, SAV-30 or multiple units. Use our interactive airflow calculator to get an instant recommendation for your roof.
Which way does your roof face?
Standard models are designed for north-facing pitches where they capture the most sun. If your best roof plane faces east, south or west, choose a tilt-panel 'T' model (SAV-10T, SAV-20T, SAV-40T, SAV-60T) — its directional panel angles toward the sun for full performance in any orientation.
Commercial and industrial
For warehouses and large cavities, one SAV-60T moves the same air as up to 52 traditional whirlybirds, and the flagship SAV-120T delivers a massive 11,220 m³/hr. When in doubt, our team will size it for you.
