What type of fan is generally selected for bag filters

The type of fan used in the bag filter should be selected according to the specific situation, mainly considering two aspects: first, it needs to meet the design gas flow rate and wind resistance parameters of the filter; The second is that the selected fan should have stable, safe, and efficient working characteristics.
The common types of fans equipped with bag filters include:
Centrifugal fan. Centrifugal fan is a commonly used type of fan, suitable for low-pressure and atmospheric dust removal systems. It has a compact appearance, simple structure, stable and reliable operation, and can achieve variable frequency speed regulation, which can better adapt to different working conditions.
Axial flow fan. Axial flow fans are mainly used for small and medium-sized bag filters and some small capacity local dust removal devices. Its advantages are small size and low noise, but it performs worse than centrifugal fans in situations with high air volume.
Other types of fans equipped according to actual conditions. For example, for situations with high dust content and density, wear-resistant fans can be chosen; For some flammable and explosive media, explosion-proof fans can be chosen.
It should be noted that when selecting the type of fan equipped with the bag filter, energy consumption and operating costs also need to be considered. Technical comparison and economic analysis should be conducted based on the actual situation to select the most suitable fan type, in order to improve the energy efficiency and efficiency of the entire dust removal system.
