The filter cartridge is a star shaped filter cartridge made of a certain length of straight filter material folded into pleats and glued head and tail. The filter cartridge has no cage bone and is easy to install.
There are many types of filter cartridge, mainly including diameter and length, pleat clearance depth and material of filter cartridge.
1. Long and thin filter cartridge (such as Φ ≤ 160, l = 1 ~ 2m), with large gap between pleats (such as 45 pleats), large included angle, few and shallow pleats, larger filtering area than the same diameter and length of the filter bag by 2 ~ 5 times, easy to clean and good effect; it is suitable for filtering and dedusting of dust concentration ≥ 15g / m, with filtering wind speed of 0.6 ~ 1.2m/min.
2. The coarse and short filter cartridge (such as Φ 350, l = 0.66M) has large diameter, short length, many pleats (120-50 pleats) and deep pleats, small pleat gap, large filtering area, 14-35 times larger than that of the same diameter and long filter bag. It is suitable for the condition with large filtering air volume and has the advantages of space saving and easy installation. However, it is necessary to select the appropriate pleat angle and depth of the filter cartridge to achieve the ideal dust removal effect. The filtering air speed should be It is generally 0.6m/min ~ 1.0m/min according to the material properties and concentration selection.
Filter cartridge filter media
1. Ordinary polyester composite non-woven fabric
2. Pet and PTFE coated polyester non-woven fabric (anti-static, oil and water-proof)
3. Long fiber filter paper and fiber composite material (can be flame retardant)
4. Imported and domestic wood pulp fiber filter paper
5. There are two main installation methods of glass fiber filter material (which can be used for dust removal and purification in high temperature, welding flue gas and other industries): vertical installation: when pulse ash cleaning, the dust is easy to fall and settle to the ash hopper, with good effect. The disadvantage is large layout space and large floor area. Inclined or horizontal installation: the filter cartridge is overlapped up and down, compact in structure, small in floor area, easy to change the cartridge, and large in processing air volume. The disadvantage is that part of the dust from the upper filter bowl falls on the lower filter bowl, which affects the cleaning effect.
Filter cartridge filter media
According to the diameter and length, the filter cartridge mainly has the following series specifications (mm)
120 × (600-2000), 150 × (600-2000), 160 × (600-2000), 200 × (600-2000), 325 × (600-1500) 350 × (600-1500) 510 × (600-1500), non-standard specifications can be processed and produced according to the needs of customers or the drawings and samples provided (the height can be up to 2m).

1. Large filtration area: compared with traditional filtration bag, pleated structure greatly improves filtration area and effectively improves filtration air volume.
2. High dedusting efficiency: high filtering accuracy, filtering efficiency up to 99.9%.
3. Small running resistance: smooth surface, strong non stick powder performance, easy cleaning and maintenance, low and stable running pressure difference, which can be used in industries with high dust concentration.
4. Convenient installation: the area of single filter element is large, the total quantity is reduced when using, the quick installation structure design is easy to install.
5. Long service life: low friction coefficient, good moisture-proof and moisture-proof, which can be repeatedly washed and reused.
