There are many types of filter cartridges, which are thin and long, thick and short.
Slender filter cartridge (such as φ ≤ 160, L = 1 ~ 2m), the pleats (such as 45 pleats) have large gaps and large angles. The filter area is 2 to 5 times larger than the filter bag of the same diameter, and the cleaning is easy and the effect is good. It is suitable for filtering dust removal with a concentration of ≥15g/m dust, and the filtering wind speed is 0.6~1.2m/min.
Short filter cartridge (such as φ350, L=0.66m) has large diameter, short length, pleats (120-350 pleats) and deep, small gap between pleats, large filter area, larger than the same diameter and long filter bag area 14～ 35 times, suitable for places with small area and small space.
