Industrial Boiler Centrifugal Fan

Industrial Boiler Centrifugal Fan
Product Overview
The Industrial Boiler Centrifugal Fan is an industrial centrifugal fan series designed for boiler ventilation systems.
The G4-73 is primarily used as a Forced Draft Fan (FD Fan) for supplying combustion air to the boiler furnace, while the Y4-73 is primarily used as an Induced Draft Fan (ID Fan) for extracting flue gas and maintaining furnace negative pressure.
The series is suitable for industrial steam boilers, hot water boilers, biomass boilers, waste heat boilers, district heating systems and thermal energy facilities.
EMS provides customized configurations according to airflow, pressure, temperature, dust concentration, gas composition, system resistance and installation requirements.
