Filtech International's 9-19 series centrifugal ventilation fan

Filtech International’s The 9-19series centrifugal fan can output high gas pressure, suitable for conveying normal or high temperature clean gas/combustible gas/corrosive gas/mixed with a few impurities, light particles/debris/short fiber materials. The most commonly used for forced ventilation, rapid drying, rapid cooling and heat dissipation, cement production line chiller cooling, clinker cooler, circulating fluidized bed system, air purification and industrial waste gas treatment, flue gas desulfurization industrial boilers or incinerators forced draft/ induced draft/ primary/ secondary air, ventilation of large mill system, industrial waste heat recovery device, blasting of smelting furnace and casting furnace, combustion of blast furnace, coal injection of blast furnace, pressurized transportation of gas, Pressurization or decompression sealing of industrial equipment. The 9-08/9-10 series fan is a series of fans that are used in a large number of industrial fields.

Applications

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,etc.

Product Features

It can output high outgas pressure and can work at higher medium temperature, suitable for any industrial occasion where high pressure & high temperature gas needs to be delivered.

2

In the case of common base, the installation is very simple and requires little support from a professional technician.

3

The bearing box is reserved with the temperature and vibration sensor installation position, which can conveniently install the fan operation monitoring device.

4

When the airflow resistance is increased, the motor load will be automatically reduced and the motor will not be burnt.

5

Customized design according to customer’s performance requirements, and optimized by CFD technology, the energy consumption is lower than similar models.

6
The tight fit between the components and the good sealing performance ensure that the output pressure is not reduced.

 

7
The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.

 

8

After the production is completed, after running test and vibration value detection, the operation is reliable.
