The Potterton 655866 Fan is a genuine replacement combustion airflow component engineered to maintain correct air movement through your boiler’s combustion chamber and flue system. By drawing in the air needed for efficient combustion and expelling flue gases safely, this fan supports reliable ignition, stable burner performance and consistent heat output. When a fan becomes worn, noisy or begins to fail, boilers can experience ignition delays, unusual noises or safety lockouts, so fitting the correct OEM replacement is essential for restoring dependable and safe operation.

This fan is compatible with Potterton boilers that specify part number 655866 in their technical documentation. To ensure correct fitment and reliable performance, always verify the part number on your existing fan or consult your boiler’s service information before installation, as combustion airflow components vary between models and configurations.

Supplied ready for direct replacement, the 655866 Fan integrates with the boiler’s original mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Potterton component helps restore proper combustion airflow, improve ignition reliability and support consistent heating performance in compatible boilers.
