EBM PAPST Axial fan W2E200HK3801

This axial fan from EBM PAPST is designed for combustion air supply and flue gas extraction in boilers and burners. It operates at 230 V and draws 0.29 A, with a power consumption of 64 W. The 200 mm impeller delivers an air flow of 1030 m3/h at a rotation speed of 2550 rpm. The fan supports three control modes: mains, PWM, and 0-10 V.

Axial fans of this class are selected by required air flow and static pressure, direction and orientation of the outlet, impeller diameter, supply voltage, and control mode (mains, PWM, or 0-10 V). The flange pattern must match the burner or boiler mounting. Verify that the replacement has the same nominal voltage, control interface, and mounting dimensions. Confirm electrical compatibility with the burner control from the appliance documentation.

Typical failure modes include worn bearings, imbalance from deposits on the impeller, a failed capacitor on single-phase AC models, and speed feedback errors that the control interprets as an airflow fault. The equipment may show a fault code or lockout due to insufficient air flow. Check for unusual noise, vibration, and the fan's ability to reach the commanded speed.
