ACV A1003265 ventilateur compact à condensation

The ACV A1003265 fan compact condens is a fan listed under Fans and Flue Gas Exhausters. Parts of this type supply combustion air and, in room-sealed appliances, also drive flue gases out of the system. In modulating premix burners, the fan speed sets the firing rate: the burner control varies the speed and the gas valve follows the airflow. When selecting a replacement fan of this kind, key parameters include air flow and pressure, direction and orientation of the outlet, impeller diameter, voltage, and control mode (mains frequency, PWM, or 0-10 V). The flange pattern must also match the appliance. Common failures in such fans are worn bearings, imbalance from deposits on the impeller, a failed capacitor, or speed feedback errors that the boiler reports as an airflow fault. Confirm that the replacement matches the original on these points before fitting.
