Fans for Kepo MC and AC pellet boilers are important for controlled flue gas extraction and a stable combustion process. A correctly functioning flue gas fan supports proper draught, airflow through the boiler and reliable operation during start-up, normal operation and shutdown.
When replacing a fan, always check the exact Kepo model, output, version, part number, connection, voltage, power rating, mounting position and technical design of the fan. This helps prevent incorrect part selection and recurring faults after maintenance or repair.

Kepo MC and AC fans for pellet boilers
Fans for the Kepo MC and AC Series are used for airflow and flue gas extraction inside the pellet boiler. The flue gas fan helps create the correct draught, supports the combustion process and contributes to stable operation during start-up, combustion and shutdown.
The correct fan is determined by the Kepo model, output, series, part number, voltage, motor power, plug connection, mounting position and technical design. Always check the original component and boiler documentation before replacing a fan.
Important checks for Kepo fans
- Check whether the fan is suitable for the correct Kepo MC or AC series.
- Compare part number, voltage, power rating, plug, mounting points and mounting position with the original component.
- Look for noise, vibration, contamination, wear, bearing issues, damaged blades or irregular speed.
- Check fault codes, start-up behaviour, flue gas extraction, draught measurement, airflow and PCB control.
- Also assess connected components such as sensors, wiring, burner pot, flue gas path, seals and pellet feed components.
Application, replacement and technical points of attention
A Kepo fan is often replaced when the pellet boiler has insufficient draught, displays fault codes, does not extract flue gas correctly, produces abnormal noise, runs irregularly or has issues during ignition and combustion. A fan fault can also be caused by contamination in the flue gas path or a problem in the electrical control circuit.
Diagnosis and installation of electrical and combustion-related parts should be carried out by a qualified technician. After replacement, rotation direction, speed, sealing, flue gas extraction, combustion air, electrical connection, fault codes and boiler parameters must be checked carefully.
Frequently asked questions about Kepo MC and AC fans
What is a Kepo fan used for?
A Kepo fan is used for airflow and flue gas extraction in the pellet boiler. The component supports proper draught and helps keep the combustion process stable.
When should a fan be replaced?
Replacement is often required in case of bearing failure, irregular speed, disturbing noise, fault codes, insufficient flue gas extraction or incorrect electrical control.
Does every fan fit every Kepo MC or AC pellet boiler?
No, the correct fan depends on the model, output, version, part number, voltage, connection, mounting position and technical design. Always compare it with the original component.
Can a fan fault also be caused by another part?
Yes, a fault can also be caused by contamination in the flue gas path, a faulty sensor, poor wiring, a PCB issue, poor sealing or insufficient air supply.
Can users install a Kepo fan themselves?
Because a fan affects flue gas extraction, combustion and electrical safety, installation and diagnosis by a qualified technician are important.
