The Vaillant fan is designed for use in ecoTEC VUW (condensing) boilers. The fan introduces fresh air into a boiler's combustion chamber, ensuring that gas is burnt correctly and extracting burnt gas at the end of the combustion process. The boiler's safety parameters ensure that no gas passes through to the main burner if the fan is not functioning correctly.
