Description
Centrifugal fan for Beretta gas boilers, model NRV137/2040-3633-010204, SKU 55724.10020. It supplies combustion air and, in room-sealed appliances, drives flue gases out of the system. In modulating premix boilers, the fan's speed determines the firing rate. Compatible with Beretta models 20058791, 20067829, 20071040, and 20072934.
Choosing and fitting
Parts of this type are selected by required air flow and pressure, direction and orientation of the outlet, impeller diameter, voltage, and control mode (mains, PWM, or 0-10 V). The flange pattern must match the burner or boiler. Verify voltage and control signal compatibility, mounting flange dimensions, and rotation direction of the impeller before ordering.
Signs of failure
Typical failures include worn bearings, imbalance caused by deposits on the impeller, a failed capacitor, and speed feedback errors that the boiler control interprets as an airflow fault, often triggering a lockout. The fan works with the air pressure switch, which confirms airflow before ignition. Check for these issues when the boiler fails to start or locks out.
