9-11 Industrial Centrifugal Blower
Some companies purchase oversized industrial centrifugal blowers for their ventilation, air supply or discharge requirements. They often generate excess energy flow and higher than normal airflow noise. Consequently, oversized fans cost more to purchase and operate. Now we roll out this 9-11 medium-pressure industrial centrifugal blower to handle your air movement applications while allowing high-volume airflow. Listed below are a few of many uses for our low-noise centrifugal fan.
1. Moving clean air at ambient temperatures
2. Feeding air to boilers, furnaces, or rotary kilns
3. Forced ventilation, forced cooling, heat dissipation
4. Air-drying materials, cooling down hot cement clinker
5. Papermaking
Features of Industrial Centrifugal Blower
1. The 9-11 medium pressure industrial centrifugal blower is capable of delivering high-pressure airflow while creating little noise.
2. With the aid of an integral base, even a layman is able to install this high-capacity fan on any desired spot.
3. Flexible coupling is used to connect between the motor drive shaft and the fan shaft. This connection method eliminates the need for belts and pulleys, requiring limited maintenance work.
4. Impellers with diameters below 1400mm run at ambient temperatures. Running at low temperature eliminates the need for bearing cooling devices, which reduces cost and maintenance.
5. When the resistance to airflow increases, the motor load will automatically decrease to protect the motor against burning out.
6. Most of our industrial centrifugal blowers are made of high quality carbon steel, but customers can choose other materials like stainless steel or other metals to construct the fan.
7. Each industrial centrifugal blower has to pass the test run and vibration check before leaving factory.
