Stainless steel bag filtration is a simple, efficient and economical filter equipment, suitable for the removal of small impurities in liquid.The liquid flows into the filter bag through the inlet of the bag filter. The impurity particles larger than the filter aperture are intercepted on the inner surface or the middle of the filter material, the liquid gathers at the outlet of the filter, then flow out the filter bag.When impurities on the filter bag accumulate to form the filter cake and the pressure difference reaches the preset value (usually 0.5 ~ 1bar), the clogging alarm device on the filter bag will alarm, and the clogging filter bag should be replaced or cleaned in time.
