Performance curve (P-Q) LWFA-E-500-02
Digitised from the catalogue curve at standard air (20 °C, 101.3 kPa, 1.2 kg/m³); one curve per voltage / speed grade (1 here, rated V). Data version: catalogue curve re-digitised 2026-09-20 (axis-calibrated, cross-checked). 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.

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.
