LWDE-250 (10")U-MWN-01 is a LONGWELL EC Mixed Flow Fan from the Mixed Flow Fans range, impeller Ø250 mm, rated 110-120 V EC, maximum airflow 1,219 m³/h, noise 69 dB(A), input power 195 W. The EC motor integrates the drive electronics: stepless speed control by 0–10 V or PWM signal, speed feedback and high efficiency at part load.

Series LWDE250: 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.
Same impeller, different speed grade, power or wiring. Step up for more airflow, step down for lower noise.
