The internal part of the bag is made of a rigid PP meltblown prefilter 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.
