The Baxi 227040 Assembly Fan is a genuine replacement combustion airflow component engineered to draw combustion air into your boiler and expel flue gases safely through the flue system. This complete fan assembly supports reliable ignition, stable flame performance and efficient heat production across different load demands.

This fan assembly is compatible with Baxi 30, 40 and 50 PF series boilers that specify part number 227040 in their parts documentation. To ensure correct fitment and reliable performance, always verify the part number on your existing fan assembly or consult your boiler’s service information before installation, as airflow components vary between models and outputs.

Supplied ready for direct replacement, the 227040 Assembly Fan installs into the boiler’s 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, improved ignition reliability and consistent heating performance in compatible PF series boilers.
