The Worcester 87172043250 Centrifugal Blower is a genuine replacement airflow component engineered to deliver controlled air movement through the combustion chamber and flue pathways of your boiler. Unlike axial fans, a centrifugal blower uses a spinning impeller to generate high-pressure airflow, helping ensure steady combustion air supply and efficient flue gas evacuation. Proper blower performance supports reliable ignition, smooth burner operation and consistent heat output, while a worn or inefficient blower can cause ignition faults, loss of flame stability or safety lockouts.

This centrifugal blower is compatible with specific Worcester and Worcester Bosch boilers that specify part number 87172043250 in their technical documentation. To ensure correct fitment and reliable operation, always check the part number on your existing blower or consult your boiler’s service information before installation, as blower types and housing designs vary between models and configurations.

Supplied ready for direct replacement, the 87172043250 Centrifugal Blower integrates with the boiler’s existing mounting points, ducting and electrical connections without modification when fitted by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore proper airflow balance, improve combustion stability and support dependable heating performance in compatible boilers.
