Product Description

High efficiency backward curved low noise centrifugal blower fan 

Product Description

The 9-11 series fan has a large flow rate and moderate pressure. 
This fan is designed for the purpose of using industrial boiler to work in the high-efficiency area and achieve the energy-saving target. 
The fan is suitable for equipped with economizer (heater) and smoke and dust removal device. 
It is a high-efficiency energy-saving product jointly designed by the national fan industry and organized by the national wind power industry and the Ministry of Machinery Industry.
It has the characteristics of high efficiency, low noise, flat performance curve and wide efficient area.
Industrial boilers of 5 ~ 35 tons/hour can be used, those with similar intake conditions and suitable performance can be used, but the maximum temperature shall not more than250°C.
Before the induced draft fan, dust removal device with a dust removal efficiency of no less than 85% must be installed to reduce the dust content of the smoke entering the fan.
It can not only reduce the pollution of the smoke on the environment, but also reduce the wear of the smoke on the fan, which is conducive to prolonging the life of the fan.

Product Feature

1.The fan can output higher gas pressure, and can provide more gas flow at the same time, low noise.
2. In the case of using the common base, the installation is very simple and basically does not require the support of professional technicians.
3. The motor shaft is elastically connected with the drive shaft. It is not necessary to tighten the belt or replace the belt frequently, and the maintenance workload is small.
4. The fan system running at normal temperature with an impeller diameter of less than 1400 mm does not require additional configuration of bearing cooling device, which reduces the user's investment and maintenance workload.
5. When the airflow resistance is increased, the motor load will be automatically reduced and the motor will not be burnt.
6.The fan is made of high quality carbon steel, and can also use stainless steel or other metal materials according to customer requirements.
7. Running test and vibration value detection after the production is completed, the fan operation is reliable
