Description
This series of fans can also be used for dust removal, mine ventilation and general ventilation systems. The medium transported by the forced draft fan is air, and the medium transported by the induced draft fan is flue gas or a gas containing impurity particles.
It can be used for more than four years when the concentration of impurities is less than 200 mg/m3.If it contains large impurities, it also can be used, but the service life is relatively shortened.
The maximum temperature used for the fan does not exceed 250°C.
It has the characteristics of high efficiency and low noise, and this series is a range of centrifugal fans with a wide range of performance.
application
Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.
