Ventilador tangencial COPREL TFR 180/C.30T-AFC HT 230V 48W

This tangential fan is a part of the type that supplies combustion air to a burner and, in room-sealed appliances, also drives the flue gases out of the system. In modulating premix boilers, the fan speed determines the firing rate: the burner control varies the fan speed and the gas valve follows proportionally. Such fans are selected by required air flow and pressure, the direction and orientation of the outlet, impeller diameter, supply voltage, and control mode (mains frequency, PWM, or 0‑10 V signal). The flange pattern must also match the burner or mixing unit. When replacing a fan of this class, check that the mounting dimensions and outlet orientation are identical to the original. Common failure modes include worn bearings, which cause noise or vibration; imbalance from deposits on the impeller; a failed capacitor preventing start; and speed feedback errors that the boiler control reports as an airflow fault. Ensure that the replacement fan is wired correctly and that the speed signal type matches the existing burner control. The 230 V 48 W rating given here is typical for smaller tangential designs in domestic or light commercial burners.
