FELT BAG WITH RIGID MELTBLOWN PREFILTER Data sheet Polypropylene filtration bag with combined technologies allowing a much longer life-span compared to standard bags. Description The inner part of the bag is made of a rigid PP meltblown pre-filter with a thickness of 10 mm. This pre-filter with a degressive porosity has a retention capacity 4 to 10 times higher than standard filters while eliminating the traces of oil present in the liquids. The external part of the bag is made of a polypropylene felt. This final step guarantees the porosity and the filtration efficiency of the whole. The 2 parts corresponding to the pre-filter and the felt are directly welded on the molded ring of your choice. This improvement compared to equivalent products on the market allows to guarantee a filtration by stage without any by-pass. Made from 100% polypropylene and without any seams, QUALIPOCHE MAX bags guarantee silicone-free filtration and are also perfectly adapted to food applications.
