Felt filter bag Multi layer

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 are 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 needle felt, and to further enhance performance, a layer of extended life felt can be incorporated. An optional mesh exterior cover can also be provided.

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