Filtech International's 8-17 Series Centrifugal Ventilation Fan

Filtech International’s The 8-17 series high-pressure small-flow fan is designed for applications requiring high pressure. Under the premise of ensuring a certain amount of air, the full pressure can reach the high pressure requirement.
It is mainly used for blasting furnace blast and other forced air supply, and can also be used for tunnels to exhaust or supply air through hard pipes.
The fans are divided into general type, explosion-proof type, anti-corrosion type and high temperature type.

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.

Structure

Drive, we usually divide the fan into:

In the process of choosing the fan, please select the appropriate fan according to the working conditions.

Product Features

1

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 housing is reserved for the installation position of the temperature and vibration sensors, and the fan operation monitoring device can be conveniently installed.

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.

9

There are a variety of options to choose from.
