ACV A1006181 zestaw do modernizacji wentylatora P100-120 V19

The ACV A1006181 is a fan upgrade kit, listed under fans and flue gas exhausters. Parts of this type supply combustion air to the burner and, in room-sealed appliances, also drive the flue gases out through the flue duct. In modulating premix boilers, the fan speed determines the firing rate; the burner control varies the fan speed, and the gas valve tracks that air flow. When replacing a fan of this class, the key selection parameters are the required air flow and pressure, the direction and orientation of the outlet, the impeller diameter, the voltage and control mode (mains, PWM, or 0‑10 V), and the flange pattern that matches the burner head. Common failure modes for such fans include worn bearings, imbalance caused by deposits on the impeller, a failed capacitor, or speed feedback errors that the boiler interprets as an airflow fault. During a replacement, check that the new fan’s electrical connections and control signal are compatible with the burner control board, and verify that the air pressure switch still confirms correct airflow after installation.
