Bag filter

liquidpressurefor the pharmaceutical industry

Bag filters, when used in food, beverage or pharmaceutical applications, must conform specific standards such as EC directives or FDA. Migration limits of contaminants from polymers into a food product have been imposed, and independent testing and certification of component materials is required to ensure these regulations are satisfied. Stringent manufacturing and warehousing conditions as well as special packaging procedures are also required to eliminate other sources of contamination. Allied Filter Systems Ltd is a leading manufacturer of food grade filter bags which fully satisfy the above conditions. The constituent materials have been chosen for their purity, giving low levels of migration and ensuring consistent high quality and performance. Available materials: Polypropylene and polyester needlefelt Polypropylene and polyester extended life needlefelt Nylon monofilament mesh Polypropylene and polyester microfibre Combined with our positive sealing Welseal (polypropylene or polyester) welded ring, needlefelt food grade filter bags have a fully welded construction as standard. The external surface of the filter bag is calendered or singed, eliminating any possibility of fibre migration into the filtrate. Each bag may be individually wrapped.
