Description

This centrifugal fan (EBM PAPST RG128/1300-3612-030203, SKU 55667.22110) supplies combustion air to boilers, burners, heat generators, and flue gas extraction systems. It provides stable air supply and efficient flue gas removal. The impeller is precisely balanced, and the fan operates at a low noise level. It has a speed feedback (tacho) signal and is intended to work with an air pressure switch. A lockout safety feature is included.

Further details

Application	boilers, burners, and flue gas extraction systems
Application type	combustion air supply and flue gas removal
Control modes	Mains on-off, PWM, 0-10V analogue signal
Key function in system	determines firing rate in modulating burners
Typical failure modes	worn bearings, imbalance caused by dirt deposits on the impeller blades, a failed run capacitor

Choosing and fitting

Fans of this type are selected by required air flow and static pressure, outlet orientation (scroll direction), impeller diameter, supply voltage, and control mode (mains on/off, PWM, or 0-10 V analogue). The mounting flange pattern and fixing dimensions must also match the existing assembly. Before ordering, compare the electrical connections and control signal with the original unit, and verify that the replacement provides the same pressure and flow characteristics.

Signs of failure

Common failure modes include worn bearings, imbalance caused by dirt deposits on the impeller blades, a failed run capacitor, and loss of speed feedback. When the speed feedback signal is lost, the boiler control board interprets it as an airflow fault and may initiate a lockout. Check the fan's bearings, impeller cleanliness, capacitor, and tacho wiring if the burner fails to operate or locks out.
