High CFM Air Small Squirrel Cage Industrial Centrifugal Blower
1. Feathers
ZK series backward inclined centrifugal fan which belongs to medium pressure and large flow centrifugal fan
impeller by wing backward vane cone, arc front panel and flat plate which has the advantages of high
efficiency, low noise, strong and durable, according to the structure can be divded into direct type(A type)
and type E(belt drive), suitable for hotels, building, hall, such as ventilation, cooling and dedusting use.

4. Advantages and characteristics
1. The industrial boiler primary air furnace wall cooling exhaust centrifugal blower can work stably at medium medium temperature, and can output large flow and low noise when meeting the pressure requirements.
2. The blade placement angle of the industrial centrifugal fan is optimized, which is more wear-resistant and has a longer service life.
3. Air baffle can be used to flexibly adjust the pressure and flow of the fan during operation. You can also choose a variable frequency motor to adjust the fan pressure and flow by changing the speed.
4. For the materials of impeller and main shaft, we will choose high strength carbon steel, low alloy steel, high temperature alloy steel, high temperature resistant high strength alloy steel under different working conditions temperature and working speed, so that the impeller and main shaft are still under high temperature Maintain reliable strength.
5. The fan system with an impeller diameter of less than 1400 mm at room temperature does not require an additional bearing cooling device, thereby reducing user investment and maintenance.
6. Annealing the impeller of the industrial centrifugal blower to eliminate the internal stress generated during the welding process and ensure that the impeller does not creep and crack.
7. The welding seam of the impeller and the main shaft is ultrasonic flaw detection to ensure that there are no welding defects and material defects, so as to ensure the strength.
8. Industrial centrifugal blower impeller undergoes high standard dynamic balance correction to ensure the stable operation of the fan.
9. There are many accessories to choose from.
