Description
The EBM PAPST RLG108/4000A-3038LH is a centrifugal fan designed for use in Protherm and Baxi boilers. It supplies combustion air to the burner and, in room-sealed appliances, expels flue gases through the flue duct. In modulating premix boilers, the fan speed determines the firing rate, with the burner control adjusting the speed and the gas valve following to maintain the correct air-to-fuel ratio. This fan operates with a mains on/off control mode and is identified by SKU 55460.97172.
Further details
| Key function in system | supply combustion air to the burner and, in room-sealed appliances, also drive the flue gases out through the flue duct |
|---|---|
| Replacement verification | always check the existing fan's markings for voltage, speed control type and physical dimensions before ordering a substitute |
| Speed signal use | the burner control varies the fan speed, and the gas valve follows to maintain the correct air-to-fuel ratio |
| Typical failure modes | worn bearings, imbalance caused by deposits on the impeller, a failed capacitor, and speed feedback errors |
Choosing and fitting
When selecting a replacement fan of this type, key parameters include required air flow and pressure, direction and orientation of the outlet, impeller diameter, supply voltage, and control mode (mains on/off, PWM signal, or 0-10 V analogue). The flange pattern must match the mating duct or burner head. Always check the existing fan's markings for voltage, speed control type, and physical dimensions before ordering.
Signs of failure
Common failure modes include worn bearings, imbalance caused by deposits on the impeller, a failed capacitor, and speed feedback errors that the burner control detects as an airflow fault. When the fan fails, the equipment may not ignite or may shut down during operation. Check the fan's operation, impeller cleanliness, and electrical connections.
