The Potterton 909001 PRI 80/100 Fan Assembly Kit is a genuine replacement combustion airflow component engineered to maintain correct air movement in your boiler’s combustion chamber and flue system. This complete fan assembly draws in fresh air required for efficient combustion and safely expels flue gases out of the appliance. Reliable airflow supports stable ignition, consistent heat output and smooth boiler operation. When the original fan becomes worn, noisy or fails, boilers can suffer ignition faults, unusual noises or safety lockouts, making proper replacement essential for dependable performance.

This fan assembly kit is compatible with Potterton Profile, Prima and Celsia boilers that reference part number 909001 PRI 80/100 in their parts documentation. To ensure correct fitment, always check the part number on your existing fan or consult your boiler’s service information before installation, as airflow components vary between models and flue configurations.

Supplied ready for direct replacement, the 909001 PRI 80/100 Fan Assembly Kit integrates with the boiler’s existing mounting points and electrical harness without modification when installed by a qualified engineer. Choosing this genuine Potterton component helps restore proper combustion airflow, improves ignition reliability and supports consistent heating performance in compatible boilers.
