Fan selection tool

Size the fan from your duty point.

Enter the operating point once: the tool returns an indicative model with a density-corrected power check and engineering cautions, then carries every value into the requirements form — one submission reaches our sales engineering team.

Published range: 500–500,000 m³/h · 500–20,000 Pa

Selection & requirements

Three steps: duty point, requirements, contact.

Results update as you type. The selection applies the same logic as BEST's internal quoting tool — density correction, tier rules and the historical blade × size × power database.

Duty point

Enter the operating point once. The matched BEST configurations update as you type — and every value carries into the inquiry below.

This is a preliminary selection, not a final fan selection. Temperature, medium, density, control range and installation still need review. Published project range: 500–500,000 m³/h · 500–20,000 Pa.

Enter an airflow and pressure above to see the matched BEST configurations.

Consistency note: this tool reverse-matches your duty point against BEST's performance curves (dimensionless φ/ψ/η) and motor database, with density correction for gas temperature and installation altitude. The configuration shown is indicative and used for preliminary quotation — it is not a certified performance curve. For other gases a medium-specific correction is applied during formal selection.

Operating requirements

Approximate values are helpful. Select “Not sure” when our engineers should advise.

What happens next

From duty point to quotation.

Step 01

We review the duty point

Our engineers check airflow, pressure, temperature, medium and installation against the real performance envelope and your process data.

Step 02

We confirm the selection

Blade family, impeller size, drive and motor are confirmed in writing, with the performance figures your project can rely on.

Step 03

You receive the quotation

A project-specific offer with construction, materials, accessories and delivery — plus drawings on request.
