Lüfterdichtung 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.
