FANOVA FS3G180-2AGL-90 Passes ERP 2026 Fan Energy Efficiency Compliance Test

Aug 17, 2026

Suzhou, China — FANOVA MOTOR announces that its FS3G180-2AGL-90 EC single-inlet centrifugal fan has successfully passed the ERP 2026 fan energy efficiency compliance test conducted in accordance with Commission Regulation (EU) 2024/1834.

The test, performed on 14 August 2026, verified that the fan meets the minimum energy efficiency requirements specified in Annex II, Point 1 of the regulation, which applies to motor-driven fans with an electric input power between 125 W and 500 kW. The measured fan efficiency at the Best Efficiency Point (BEP) reached 45.87%, exceeding the required minimum of 34.28% — a margin of 11.6 percentage points. After applying the correction factors specified in Annex III (Cp × Cc × Cguard), the corrected efficiency reaches 54.09%.

What Is ERP 2026?

ERP 2026 refers to Commission Regulation (EU) 2024/1834, published on 4 July 2024, which sets ecodesign requirements for fans driven by motors with an electric input power between 125 W and 500 kW. The regulation:

Replaces the earlier Regulation (EU) No 327/2011
Applies to fans at their best efficiency point (BEP), including fans integrated into other products
Defines minimum fan efficiency grades (N values) per fan type, measurement category, and efficiency category
Requires quantified fan efficiency information at part load to help system designers optimise energy use
Mandates the availability of spare parts and end-of-life information, supporting circular economy objectives

For the FS3G180-2AGL-90, the applicable efficiency grade N is 52 (forward curved centrifugal fan, measurement category A/C, static efficiency category, Pe < 5 kW).

Compliance Calculation

Minimum Efficiency Requirement (Annex II, Point 1)

For Pe < 10 kW, the minimum fan efficiency is:

η_min = 4.56 × ln(Pe) − 10.5 + N   [%]

With Pe = 0.2053 kW and N = 52:

η_min = 4.56 × ln(0.2053) − 10.5 + 52
      = 4.56 × (−1.583) − 10.5 + 52
      ≈ 34.28%

Correction Factors (Annex III, Point 6.1)

The measured fan efficiency is corrected as:

η = Cp × Cc × Cguard × (Pu / Pe)

where Pu = qv × Δp is the fan gas power at BEP.

Factor	Value	Basis
Cp (power conversion)	1.0	AC supply, no <100 V DC converter
Cc (part-load compensation)	1.1792	VSD equipped, Pe < 5 kW: 1 + 0.0812 × Pe⁻⁰·⁵
Cguard (guard compensation)	1.0	No guard

η = 1.0 × 1.1792 × 1.0 × 0.4587 = 54.09%

Verdict

Measured η at BEP

45.87%

≥ 34.28% · Compliant

Corrected η

54.09%

≥ 34.28% · Compliant

The fan meets the ERP 2026 minimum fan efficiency requirements of Annex II, Point 1.

Why This Matters for System Designers

The FS3G180-2AGL-90 delivers a measured efficiency 11.6 percentage points above the regulatory minimum, providing:

Lower energy cost: higher efficiency at BEP means less electrical input per unit of delivered airflow
Design headroom: the margin over η_min protects against unit-to-unit variation and verification tolerances (93% of declared value at BEP)
Simplified compliance documentation: the test report supports the Internal Design Control conformity assessment under Annex IV of Directive 2009/125/EC (ESPR (EU) 2024/1781)
Future-proofing: compliance is verified now, ahead of the regulation's application dates
