LWFA-E-300-01 is a LONGWELL LWFA Series Direct Drive Centrifugal Blower from the Impeller Ø280–500 mm range, impeller Ø300 mm, maximum airflow 4,300 m³/h, maximum static pressure 720 Pa, noise 72 dB(A). The fixed-speed AC external-rotor motor is simple, robust and cost-effective for constant-duty applications.

Technical data

Model LWFA-E-300-01
Motor type AC
Max. airflow 4,300 m³/h
Max. static pressure 720 Pa
Noise 72 dB(A)
Impeller diameter Ø300 mm
Blade diameter 300mm

Typical applications

  • Commercial kitchen extraction
  • Ventilation units and AHUs
  • Process and fume extraction

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 (Ø300 mm · AC)

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