HIGH-PERFORMANCE FILTR ATION BAG HE20 Data sheet High-performance polypropylene filtration bag The internal filtering part is made of 2 to 4 layers of high thickness meltblown filtering materials. The construction of the bag allows for deep retention through successive layers to maximize dirt holding capacity and extend service life. The meltblown technology ensures efficient and repeatable filtration. The meltblown filter materials have been carefully selected and tested by our analytical laboratory to guarantee a filtration efficiency of 95% at the announced porosity (BETA RATIO = 20). The results of the tests carried out on a standardized bench are available on request. The upstream and downstream parts are made from spunbond filtering materials with very good mechanical properties and avoiding any risk of fiber release. Made of 100% polypropylene and without any seams, QUALIPOCHE HE20 bags guarantee silicone-free filtration and are also perfectly adapted to food applications. QUALIPOCHE POHE20OA bags incorporate an additional hydrocarbonabsorbing pre-filter. This filler is made of a very thick meltblown and specially treated oleophilic material. Characteristics & benefits • Filtration efficiency of 95% at the indicated porosity. • Beta ratio of 20 at the indicated porosity. • Wide range from 1,5 to 32 µm. • 100% polypropylene. • Welded design to prevent all risks of contamination. • Available with O-ring or molded ring for a reinforced seal. • Complies with EU 1935/2004, EU 10/2011 and its amendments, EU 2023/2006 (in IW code). • Made from silicone-free materials. • Lot number on bags and packaging. Chemical compatibility Polypropylene Option It is possible to replace the spunbond top layer with a polypropylene felt bag (PO or POT). This design allows the integration of an additional nominal depth pre-filter in order to increase the life span of the bag. This solution is perfectly adapted in the case of a too fast clogging of the upstream spunbond layer (filming phenomenon). Reference example : QPT-20-PO-25-POHE20-15-EAP For a POHE20 20 µm bag with 25 µm felt prefilter. +++ Excellent | ++ Good | + Fair | - Not compatible Note: displayed temperatures are only applicable for metal rings. If polypropylene ring, do not go above 90°C. Conditions of use Max pressure loss Recommended replacement differential pressure Max flow rate
