Question 1

What is AHU selection software?

Accepted Answer

AHU selection software sizes and configures air handling units: it selects fans, coils, filters and heat-recovery components against an operating point (airflow, external pressure, design temperatures), computes pressure drop, SFP and energy class, and produces the technical documentation a manufacturer or consultant needs to quote the unit. AirSelect3D does this in the browser with a 3D drag-and-drop designer and certified manufacturer calculation engines.

Question 2

How does AirSelect3D compute the Eurovent energy class?

Accepted Answer

Every selection computes winter and summer fs-Pref ratios per Eurovent ECP-05-2026, checks SFP thresholds to EN 16798 and the ErP (NRVU) requirements, and stamps the verdict — including engine version, catalog version and selection ID — into the printable dossier for full auditability.

Question 3

Which manufacturers' data does AirSelect3D use?

Accepted Answer

AirSelect3D runs each manufacturer's own calculation engine or certified catalog in an isolated side-car process: Camfil filters, Ziehl-Abegg and eBM Papst fans, Friterm heating and cooling coils, Recuperator and Klingenburg plate heat exchangers, and Hoval rotary heat recovery. Results carry a source tag (DLL or catalog) on every row.

Question 4

What is SFP (specific fan power) and why does it matter?

Accepted Answer

SFP expresses how much electrical power the fans absorb per unit of airflow, in W/(m³/s). EN 16798 defines SFP classes, and European ErP regulation caps internal SFP for non-residential ventilation units (NRVU). AirSelect3D recalculates SFP live as you edit the unit, so a non-compliant configuration is visible immediately — not after the quote has shipped.

Question 5

Can I export drawings and BIM files from AirSelect3D?

Accepted Answer

Yes. One click renders a 14-page technical data sheet PDF with general arrangement drawings in 2D and 3D isometric, plus DXF for AutoCAD and IFC for BIM workflows, and a bill of materials in CSV or XLSX.
