The filter area of the filter cartridge refers to the effective area of the filter material on the filter cartridge. When we arrange the filter cartridge vertically, the higher the filter cartridge, the more beneficial it is to save the overall cost. However, if the filter cartridge is too high, it will be difficult to clean the ash. At present, the generally long filter cartridge in the world is 2 meters. If the dust concentration at the inlet of the dust collector is higher, the number of folds of the filter material can be selected a little less, and the width of the filter can be selected shallower, that is, the filter area is less, which is more conducive to cleaning. The filter wind speed for the cartridge type dust collector is generally 0.6 to 1.8 m/min. The ideal filtration wind speed is 0.9m/min.

When the dust concentration is high, you can consider choosing a lower filter wind speed. Reducing the filter wind speed is beneficial to improve the filter efficiency of the dust collector, extend the service life of the filter cartridge, reduce the working resistance, and improve the ventilation performance. However, the cost of the dust collector has increased, but in some special cases, the filter wind speed of the filter can also be selected to be more than 3m/min.

Calculation of filter area of filter cartridge：

Calculation formula of effective filter area of filter cartridge:
A=L×2×N×M
A-filter area m2
L-filter fold width m
N-filter folds (pieces)
M-filter cartridge height m
