Performance curve (P-Q) LWBA2E220-092NS-05
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 230 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.

Series LWBA2E220: 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.
