Brick Kiln Industrial Centrifugal Fans High Temperature Induced Draft Fan

Brick Kiln Industrial Centrifugal Fans High Temperature Induced Draft Fan

4-73 series boiler centrifugal fans are applicable to industrial boiler that burns a variety of media and equipped with devices to reduce smoke and dust. The conveying gas temp 250°C. The drive means of this fan has C-type and D-type two kinds with water-cool, bearing base and air volume regulating door, If a de-oscillator is chosen, the user can lace the fan in the concrete plane. It is easy to install and debug with noneed for the bolt. Our company can provide the stainless steel heat boiler centrifugal blower when the temperature of air must exceed 250 °C.

1. Application:
4-72 centrifugal ventilators are suitable for Petroleum, Chemical industry, metallurgy, Electroplating, Sewage treatment, Brewing, Textiles, Electronics and other area. This fans are used for ventilation and air-change.
2.Advantage.
This ventilator has the features such as:high efficiency, low noise, stable pressure curve and anti-corrosion and energy saving, convenient installation, wide application.
3. Model
This kind of centrifugal fan are divided in to ACD three connect way, type A means the motor connect with the impeller directly, the C type means the motor and the impeller connected by the belt, type D means connected by the coupler.

Wheel
The wheel shall be of the backward curved centrifugal steel type and all welded. The wheel shall be statically and dynamically balanced up to ISO 1940-G4.0 standard. Stable airflow and low sound should be ensured as the wheel is operating at the maximum allowable speed. Drop in performance shall be avoided as the operating point moves up or down. The wheel shall be readily removable for cleaning or maintenance.
Fan Housing
