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

This model's estimated electrical input power is about 391 W, which falls inside the 125 W – 500 kW band covered by Regulation (EU) 2024/1834, applicable to fans first placed on the EU market from 24 July 2026.

Compliance is determined at your duty point, not by the model alone. The same fan can meet the requirement in one project and miss it in another, because the regulation evaluates efficiency across the real operating range rather than at the best efficiency point only.

Check this model at your duty point → Request test data & documentation →

Input power is estimated from rated voltage and current for scope indication only. Final selection must be confirmed against the duty point (airflow / static pressure / voltage / control method) and project verification. See the ErP 2026 requirements guide.
