Available EC axial fan models

EC Axial fan

LONGWELL EC axial fan configurations combine an electronically commutated motor with the fan assembly. Compare electrical input, air performance and acoustic data at the duty point required by your equipment.

Model details to confirm

  • Assembly: confirm impeller diameter, overall depth, mounting points, airflow direction and inlet clearance from the model drawing.
  • Materials and protection: check housing and impeller materials, permitted temperatures and protection level for the selected configuration.
  • Electrical interface: confirm supply, speed command, feedback, alarm functions and wiring before connection.
  • Validation: agree airflow, sound and temperature acceptance criteria in your equipment before approving the sample.

Catalogue and selection support

Use the EC axial fan catalogue to identify candidate models. Request the corresponding curve, drawing and applicable product documents; family-level information does not establish every model’s options.

2026 catalogue example: LWAE3G450SS-5MNW-01

The EC450 catalogue lists 220 V, 50/60 Hz and 1,590 rpm for this model. Its maximum/free-air airflow is 6,695 m³/h; catalogue input power is 420 W at 0 Pa. Compare the curve at the installed system pressure before selection. These values describe this example, not every EC axial fan. Open the model table, curve and installation drawing (PDF, page 1).
