Pellicle Series – Needle Felt Filter Bag
Pellicle Needled felt liquid filter bags is the most common media used in economic disposable bag filters. Its fibers are locked together when they pass through beds of special barbed needles, entangling them into a strong matrix. The downstream side is signed using a special heat process to eliminate fiber migration. This rugged media is ideal for fabrication by both sewing and welding. Available in a wide range of materials, needled felt can be used in a vast range of liquids and gases of low to medium viscosity. They can be applied to remove hard particles or, in some cases, soft particles and jels. Kfilter offers needled felts in PO, PE, PA and PTFE in the full range of bag sizes. Connect Now!
