Typical applications

  • Air handling units (AHU) and rooftop units (RTU)
  • Data-center CRAH / CRAC units and fan walls
  • Dust extraction and process ventilation
  • Fan filter units and air purifiers

Series LWFA4E225: 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 (Ø225 mm · AC)

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