G4-68, Y4-68 centrifugal ventilation and induced draft fans are suitable for ventilation and induced draft of steam boilers below 230t/h in thermal power plants. In the absence of other special requirements, C4-68 is also suitable for mine ventilation and general ventilation. .

The medium conveyed by the fan is air, and the minimum temperature does not exceed 80°C. The medium conveyed by the induced draft fan is flue gas, and the maximum temperature shall not exceed 250°C. There must be a dust removal device with a dust removal efficiency of not less than 85% in front of the induced draft fan, so as to reduce the dust content of the flue gas entering the fan and improve the service life of the fan.

Both the ventilator and the induced draft fan are single-inhalation air intake, with seven machine numbers No8, No9, No10, No11.2, No12.5, No14, and No16. Each type of fan can be made into two types: right-rotating or left-rotating. Looking at the fan from one end of the motor, the impeller rotating in a clockwise direction is called a right-rotating fan, otherwise is called a left-rotating fan

For the sake of convenient installation and debugging, the overall support and vibration reduction support of steel structure are also supplied.
