The security filter is as compressed inline filter housing, and its working principle is to use the 5um pores of the PP filter element for mechanical filtration.  Trace suspended particles, colloids, microorganisms, etc. remaining in the water are trapped or adsorbed on the surface and pores of the filter element.  With the increase of water production time, the filter element will gradually increase its operating resistance due to the pollution of the retentate.  When the water pressure difference between the inlet and outlet reaches 0.1MPa, the filter element should be replaced.  The main advantages of the security filter are high efficiency, low resistance and easy replacement.

Filter housing's structure and principle:

The security filter adopts a shaped filter material.  Under the action of pressure, the raw liquid passes through the filter material, the filter residue remains on the tube wall, and the filtrate flows out through the filter material, so as to achieve the purpos
