The Baxi 229421 Spare Fan Assembly Kit is a genuine replacement combustion airflow component engineered to maintain correct air movement through your boiler’s combustion chamber and flue system. This complete fan assembly draws in the air needed for efficient combustion and expels flue gases safely, supporting stable ignition, smooth burner operation and consistent heat output. When the original fan loses efficiency, becomes noisy or fails altogether, replacing it with the proper OEM kit helps restore reliable performance and reduce the risk of ignition issues or boiler lockouts.

This fan assembly kit is compatible with Baxi Solo 2 PF boilers within the 30 60 range that specify part number 229421 in their parts documentation. To ensure correct fitment and optimal performance, always verify the part number on your existing fan or consult your boiler’s service information before installation, as airflow components vary by model and configuration.

Supplied ready for direct replacement, the 229421 Spare Fan Assembly Kit installs using the boiler’s original mounting points and connects to the existing electrical harness without modification when fitted by a qualified engineer. Choosing this genuine Baxi component helps restore proper combustion airflow and supports dependable heating performance in compatible Solo 2 PF boilers.
