The Potterton Prima 80/100 Fan Assembly Kit (909001) is a replacement boiler fan assembly designed for compatible Potterton Prima and Profile Prima boilers, as well as selected related models.

The fan plays an important role in boiler operation by supplying air to the combustion chamber and helping remove combustion gases. A faulty fan can prevent a boiler from operating correctly, as the boiler's safety controls are designed to prevent burner operation when the fan is not functioning properly.

This replacement fan assembly kit is suitable for a range of compatible 80 and 100 model boilers, including selected Potterton Prima, Profile Prima, British Gas Celsia and Scottish Gas appliances.

Before ordering, check your boiler's exact model and existing part number to confirm compatibility. Boiler fan assemblies are safety-critical components and must be installed and checked by a suitably qualified Gas Safe registered engineer.
