DC Centrifugal Fan Selector

Enter a required airflow, static pressure, voltage and control interface, or look up an existing DC centrifugal fan model number. The selector checks catalog data across 26 performance curve groups (48 published electrical variants) in Proventofan's 11 DC centrifugal fan frame sizes (133mm–450mm) and flags exactly what still needs curve or drawing confirmation before ordering.

Duty point and installation inputs
Modbus RS-485 is only published on -90/-91/-20/-21 series variants. -70/-71 series variants are PWM + 0-10V only.
Orientation only applies to the 310mm and 355mm frame sizes, which publish separate L/Y variants; every other size ignores this filter.
Preliminary result
Catalog candidates will appear here.The selector does not issue a final model approval or replace the characteristic curve and dimensional drawing.
Preliminary catalog match: this tool checks published maximum airflow and maximum static pressure against your input; it does not confirm both are achievable at the same operating point on the performance curve. Confirm the characteristic curve image, dimensional drawing (N or K version), and voltage range before ordering.
