Required airflow Required static pressure

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.

LWFA-E-450-02 is a LONGWELL LWFA Series Direct Drive Centrifugal Blower from the Impeller Ø280–500 mm range, impeller Ø450 mm, maximum airflow 10,500 m³/h, maximum static pressure 750 Pa, noise 80 dB(A). The fixed-speed AC external-rotor motor is simple, robust and cost-effective for constant-duty applications.

Technical data

Model	LWFA-E-450-02
Motor type	AC
Max. airflow	10,500 m³/h
Max. static pressure	750 Pa
Noise	80 dB(A)
Impeller diameter	Ø450 mm
Blade diameter	450mm

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 (Ø450 mm · AC)

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