Durable polypropylene (PPX) and polyester (PEX) none-woven micron felt bag filters. Design effort focuses on extending filter's service life. The inner surface of pre-filter layer is coarse but keep high removal efficiency to form graded pore depth structure. Gels and coarse contaminant particles are trapped and retained by the pre-filter layer in order to protect and prolong the service life of the primary layer.
Such formulation is effective in slowing down the premature formation of filter cakes, therefore successfully extend filter's service life. To prevent fiber migration, a layer of compressed non-woven material is attached as cover. Lab tests have shown that the average service life is 85% to 110% longer than standard PP and PE bags, depending on application conditions.
