What is the difference between a filter cartridge and a filter bag?

The filtrate filter surface of the liquid filter bag is treated by special singling, which not only effectively prevents the fiber from leaving the polluted filtrate, but also avoids the excessive blockage of the filter hole caused by the traditional roller pressing treatment and shorting the life of the filter bag. Suitable for filtering general industrial liquids such as electroplating E, D paint, ink, paint, food and other chemical liquid; Acid and alkali resistant fiber has high mechanical strength and can be used repeatedly.

The dust filter bag has excellent chemical stability and heat resistance, which is the representative of the highest performance applied to the filter material industry, and is also the highest performance variety of all commonly used filter materials, and has reached a high level in filtration efficiency and filtration accuracy. Commonly used filter materials are PE,PP,PTFE,PMIA,NMO and so on.

The filter cartridge is a cylindrical component used for filtering, which is generally divided into a filter cartridge used for filtering gas media and filtering liquid media. Filter the liquid medium filter cartridge is generally installed in the pipeline filter, the shape is common cone, so it is also called cone filter. The filter material of the common filter cartridge is wood pulp fiber filter paper and spunbond polyester fiber non-woven fabric, of which the polyester non-woven fabric can be covered with film, anti-oil and waterproof, anti-static treatment.

The advantages of the filter cartridge compared with the filter bag are:

1, pleated filter cartridge, increase the filtration area, occupy less space;

2, improve the processing air volume;

3, reduce the filter wind speed;

4, easy to clean ash, reduce pressure difference;

5, save compressed air;

6, easy installation and maintenance;

7, high dust removal efficiency.

8, filter cylinder life extension.

9, Venturi tube, cage all exempt.

10, the overall cost is low

Of course, the filter cartridge is not universal in the dust removal industry, and some conditions can not completely replace the filter bag

1, high temperature environment, usually higher than 120℃ conditions do not recommend the use of filter cartridge, high cost

2, high concentration environment, if the dust concentration is very large, we do not recommend the use of filter type.
