Digitised from the catalogue curve at standard air (20 °C, 101.3 kPa, 1.2 kg/m³); one curve per voltage / speed grade. The system resistance curve depends on the actual ductwork — confirm the operating point on site. Need an engineer to verify the duty point? Contact us or add the model to your RFQ and note the duty point.

Series LWBA4E190: models in the same series share the impeller and motor platform and differ in speed grade, voltage or lead-out / terminal-box configuration — compare them in the table below or ask for the best fit at your duty point.
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 impeller (Ø190 mm · AC)
Same impeller, different speed grade, power or wiring. Step up for more airflow, step down for lower noise.
