The Hamworthy 533704007 Fan (Ametek 150134-08) is a genuine replacement combustion airflow component designed to maintain correct air movement through the boiler or heating appliance’s combustion chamber and flue system. This Ametek-supplied fan draws in the necessary fresh air for efficient combustion and expels flue gases safely out of the unit, supporting reliable ignition, stable flame performance and consistent heat output. When a fan begins to wear, becomes noisy or loses efficiency, symptoms such as delayed ignition, unusual sounds or safety lockouts can occur, so fitting the correct OEM-specified fan helps restore dependable and safe operation.

This fan is compatible with Hamworthy systems that reference part number 533704007 and Ametek model 150134-08 in their service and parts documentation. To ensure correct fitment and optimal performance, always verify the part number on your existing fan or consult your appliance’s service information before installation, as airflow assemblies vary between models and configurations.

Supplied ready for direct replacement, the 533704007 Fan integrates with the original mounting points and electrical connections without modification when installed by a qualified engineer or heating technician. Choosing this genuine Hamworthy replacement helps reinstate proper combustion airflow, improves ignition reliability and supports consistent heating performance in compatible appliances.
