Fan gasket De Dietrich 7705922

The fan gasket creates an airtight seal between the combustion fan and the boiler or burner housing. This prevents air leaks that can disrupt the air-fuel ratio, reduce efficiency, and cause noise. Made from high-temperature resistant material, it ensures a durable seal even under continuous operation. When servicing the fan or replacing it, a new gasket is essential to restore proper sealing. This spare part is a common item in boiler maintenance and repair kits, helping to maintain optimal combustion conditions and prolong the life of your heating system.
