EBM PAPST Centrifugal fan 8556 N 9274014210

Centrifugal fan by EBM PAPST, model 8556 N, SKU 9274014210. It operates at 230 V supply voltage, draws 0.05 A current, and rotates at 2800 rpm. The fan measures 80x80x38 mm and is designed for use in burners and boilers to deliver combustion air or exhaust flue gases. Its outlet orientation must match the burner housing for proper installation.

When selecting a replacement centrifugal fan of this type, ensure the supply voltage, current consumption, and control mode (mains voltage, PWM, or 0-10 V) are compatible with the burner's electrical system. Verify the physical dimensions, mounting flange pattern, and outlet orientation match the original fan. Also check that the required air flow and pressure at the operating point are adequate for the burner's needs.

Common failure modes for centrifugal fans include worn bearings, imbalance from deposits on the impeller, a failed capacitor, or speed feedback errors. These issues may cause the burner to report an airflow fault, operate inefficiently, or shut down. Inspect the fan for unusual noise, vibration, or reduced airflow, and check the electrical connections and capacitor if problems occur.
