The Broag S100036 Fan is a genuine replacement combustion airflow component designed to control and maintain proper air movement in compatible Broag and boiler systems. By drawing in the correct volume of fresh air for combustion and expelling flue gases safely through the flue system, this fan supports reliable ignition, efficient combustion and consistent heat output. If the existing fan becomes worn, noisy, or begins to fail, the boiler can experience ignition problems, unstable flame, unusual noises or safety lockouts, making correct replacement essential for dependable performance.

This fan is compatible with systems and appliances that specify Broag part number S100036 (often referenced with model codes like RG148 or 1200-3633-010202) in their technical documentation. To ensure proper fitment and reliable operation, always check that the number on your existing fan matches before installation, as combustion airflow components vary by model and configuration.

The S100036 Fan is supplied ready for direct replacement, integrating with the original mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Broag component helps restore correct combustion airflow, improves ignition reliability and supports dependable heating or hot water performance in compatible systems.
