Description
The EBM PAPST RG175/2000-3633-010204 (SKU 55667.14001) is a centrifugal fan designed for use in boilers, burners, and industrial thermal equipment. It supplies combustion air to the burner and, in sealed appliances, expels flue gases. The fan's speed is controlled by the burner control to modulate firing rate, ensuring correct air-fuel ratio. This model is identified by manufacturer part number 55667.14001.
Further details
| Air pressure switch | an air pressure switch downstream confirms that airflow is present before ignition is allowed |
|---|---|
| Connection to burner control | connected to the burner control which issues the start and speed commands |
| Function | supply combustion air to the burner and, in room-sealed appliances, also drive the flue gases out of the heat exchanger |
| Modulating operation | in modulating premix boilers, the fan's speed determines the firing rate: the burner control varies the fan speed and the gas valve follows to maintain the correct air-fuel ratio |
| Replacement verification | correct replacement requires verifying the part number against the original fan and checking that all electrical and mechanical interfaces match the existing installation |
| Speed signal use | the fan speed signal is used by the gas valve or air damper actuator to adjust fuel and air proportionally |
| Typical failure modes | worn bearings, imbalance caused by deposits on the impeller blades, a failed starting or run capacitor, and speed feedback errors that the boiler control interprets as an airflow fault, often leading to a lockout |
Choosing and fitting
When selecting a replacement centrifugal fan of this type, verify the required air flow and pressure, outlet direction, impeller diameter, supply voltage, and control mode (mains on/off, PWM, or 0-10 V analogue). The flange pattern must match the burner or boiler mounting. Check that all electrical and mechanical interfaces align with the existing installation.
Signs of failure
Typical failure modes include worn bearings, imbalance from deposits on impeller blades, failed start or run capacitors, and speed feedback errors. These issues may cause the boiler control to interpret an airflow fault, leading to lockout. Check for unusual noise, vibration, or error codes related to airflow.
