Engineering files (on request)

CAD files exist for this model and can be released for assembly checks in SolidWorks / CATIA / Creo / Inventor.

CAD models contain the blade geometry and are not downloadable. Tell us the project; an engineer sends the file after a short check, normally within 1 business day.

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.

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 (Ø280 mm · AC)

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