This configurator provides indicative system selection based on standard pathway rules. All outputs should be verified by a qualified mechanical engineer against AS/NZS 1668, relevant health facility guidelines (AHIA/AusHFG), and site-specific conditions. Hybrid Theatre, high ACH (≥25 ACH), and non-rectangular room geometry always require custom engineering review. Diffuser area calculations assume standard air velocity for the application type — confirm with Mediflow engineering team before finalising design.
