Bag Filtration

Bag filters are available in three FDA compliant media formats, of which polypropylene felt is suitable for the majority of applications. Polyester felt should be selected where solvent compatibility and high temperature are required. For coarser filtration, mesh, which is washable and reusable, is offered from 50 – 1000 micron. Available to special order are double-layer polyester and polypropylene extended life, nylon multi-filament, Teflon and oil-removal media.

Although cartridge filtration can give more accurate results, when bag filtration is correctly specified, superior, effective and economic performance will be achieved, where comparable cartridge filtration housings would require far greater capital and consumable expense.


  • SPECTRUM Economic Bag Polypropylene Size 3 Polypropylene Neck Ring - GroAqua

    Spectrum SPECTRUM Economic Bag Polypropylene Size 1 Polypropylene Neck Ring

    Bag filters are used to remove sediment, debris and gelatinous particles from liquids in higher flow or viscosity applications.Utilising a traditional single layer manufacturing method, the SPECTRUM Economic range offers the greatest option in terms of filtration media and neck seal type, providing a suitable solution for most bulk solid removal applications.Due to an all welded seam construction, Economic bags are capable of holding several kg’s in weight whilst maintaining filter integrity and their heavy duty handles make changeouts simple, avoiding operator contact with the unwanted filtrate.Each bag is manufactured from lot controlled raw media, individually labelled and finished with a total glazing process to inhibit fibre release.Features & Benefits All sizes, micron ratings and neck ring options are available Each bag includes a handle for fast, easy and cleaner removal Seams on Polypropylene and Polyester felt bags are welded to prevent bypass Materials of construction Filter Media: Polypropylene, Polyester, Nylon Neck Ring: Polypropylene Construction: Thermal Bond (Nylon is sewn) Construction notes Economic felt bags are of welded construction, where the bag fabric is fused together to create a strong seal, reducing the possibility of loose, fibrous edges migrating downstream Economic nylon mesh bags are heavy-duty double stitched Certification WRAS approved product BS6920 compliant materials
