The Baxi 7841063 Fan/Mixer Assembly is a genuine replacement component designed to combine the functions of combustion air delivery and air/gas mixing in a single integrated unit. This assembly draws in the correct volume of air and blends it with gas before the mixture enters the burner, helping achieve stable ignition, efficient combustion and consistent heat output. A worn or malfunctioning fan/mixer can contribute to ignition delays, noisy operation or boiler lockouts, so fitting the correct OEM part is key to restoring smooth, reliable performance.

This fan/mixer assembly is compatible with Baxi boilers in the 24 kW to 30 kW range that specify part number 7841063 in their parts documentation. To ensure correct fitment and optimal performance, always check the part number on your existing assembly or consult your boiler’s service information before installation, as airflow/mixing assemblies vary between models and output sizes.

Supplied ready for direct replacement, the 7841063 Fan/Mixer Assembly integrates with the boiler’s existing mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Baxi component helps restore proper combustion air delivery and efficient air/gas mixing, supporting dependable ignition and heating performance in compatible boilers.
