The free, NCC/BCA-aware online fan selector for Australian engineers, specifiers and contractors — search Allvent’s live catalogue by duty point, verify compliance, and generate project documentation in one place.
Launch Fan Selection StudioEnter the airflow and pressure your project needs and search fans, roof cowls, silencers, ancillaries and speed controllers from Allvent's real, current product range — not a static PDF catalogue.
Every result includes a real National Construction Code fan-efficiency compliance check, with an actual margin — calculated from the fan's own performance data, not estimated.
See the fan's real performance at the closest point on its own published curve to what you asked for — the actual operating point the building will get, not just the number you typed in.
Octave-band sound data, efficiency, motor and dimensional detail, plus CAD and Revit downloads for every fan — the same detail an engineer needs to actually specify it.
Dedicated selection engines for roof cowl pressure loss and silencer attenuation — not the same generic fan search stretched to fit.
Line up multiple fans against the same duty point and see exactly where each one wins or loses, before you commit to a selection.
Add selections to a project and generate a professional PDF or Excel schedule directly from the Studio — no re-keying results into a separate document.
Projects can be shared across your organisation, so colleagues can see and build on each other's work instead of starting over.
NCC Section J fan-efficiency requirements are a genuine engineering calculation, not a checkbox — demonstrating either component-level compliance (peak fan efficiency, variable-speed capability) or whole-of-system compliance against a reference design. Most fan selector tools, in Australia and internationally, don’t attempt this. The Fan Selection Studio runs the real calculation against each fan’s actual performance data and reports a real margin — so you know it’s compliant before you specify it, not after.
