Typical applications

  • Indoor air-conditioning units
  • Air curtains and door air barriers
  • Elevator and cabinet ventilation
  • Linear air supply in appliances

Series LWCD90520: 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 (Ø90 mm · DC)

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