Nameplate values: maximum airflow is measured at zero static pressure and maximum static pressure at zero airflow; the two never occur together. Confirm the operating point on the performance curve. Final selection is subject to the duty point (airflow / static pressure / voltage / control mode) and project verification.
Alternatives with the same frame size (43 mm · AC)
Same impeller, different speed grade, power or wiring. Step up for more airflow, step down for lower noise.
