ErP 2026 scope check — Regulation (EU) 2024/1834

EU fan efficiency documentation for LWFE3G400-102PS-02. Regulation (EU) 2024/1834 sets minimum-efficiency requirements from 24 July 2026. For most applicable fans, the assessment uses BEP-based values.

Separate partial-load or specified-duty information requirements apply from 24 July 2027. Confirm the full model, verified BEP electrical input power, test configuration, exclusions and any applicable transition. Catalogue ratings and motor efficiency classes alone do not establish conformity.

Read the efficiency requirements → Request BEP test data & documentation →

Send your airflow, static or total pressure, voltage and control requirements to request configuration-specific test data and documentation, and separately verify performance at the actual duty point. See the ErP 2026 requirements guide.
