Airflow GBDF4 Flue Dilution Fan

Airflow GBDF4 Flue Dilution Fan The Airflow GBDF range of flue dilution fans are suitable for industrial and commercial atmospheric gas fired boilers and water heaters. Regulations require that if the products of combustion are dispersed at a low level, then the CO2 content must be 1% or below, The Airflow flue dilution fans achieve this by introducing fresh air into the boilers discharge flue duct and diluting the flue gases. With the correct selection of fan for the boiler rating and the recommended flue duct layout the 1% CO2 level will be met. Features include: - • Built in self proving pressure safety switch (offering a safety interlock with the appliance in instances of flue blockage or fan failure) • Simple electrical connections, designed with the installer in mind. • Eliminates the need for unsightly external flues; and the need for expensive installation or refurbishment of internal flues. • Efficient and quiet centrifugal fans capable of overcoming system resistance in flue duct runs.
