Multi Layer Felt Filter Bags

Multi Layer felt filter bags provide graded density, multi stage depth filtration in a single filter bag. A high dirt loading capacity and superior filter bag lifetime is achieved by selecting the optimum micron ratings of the pre-filtration and final filtration layers in accordance with the needs of the filtration process.

Multi Layer filter bags can be produced with 2 or 3 layers of polypropylene or polyester needlefelt, and to further enhance performance, a layer of extended life felt can be incorporated. An optional mesh exterior cover can also be provided.

As well as providing excellent service life, multi layered bags are excellent for filtration of fluids containing gel-like particles. Example applications include filtration of paints, coatings, chemicals and foodstuff. Multi Layer filter bags conform to EC food contact directives and are manufactured under silicone free conditions.
