Boosting filter performance is easy with Valmet Disc Filter Bags. They incorporate everything from a perfect fit to the best materials and a long lifetime – everything you need from a disc filter bag. Valmet is the global market leader in disc filter bags.
All Valmet Disc Filter Bags, regardless of the material, are designed and made to fit perfectly in demanding applications. We use a computer-controlled laser cutter with coded dimensions to ensure absolute precision. In addition to tight and durable stitches, the fabric edges are nonfraying.
To check that the bag size is exactly right, we fit the bags on actual-size model sectors supplied by filter manufacturers.
Valmet uses polypropylene (PP) or Kynar as filter cloth material, both of which provide optimal filtration results. The polypropylene fiber is ideal for normal conditions, whereas the Kynar fiber is ideally suited to more demanding conditions with its excellent tolerance of high operating temperatures and chemical resistance properties. The high-quality Kynar filter bags are fitted with acid-proof zippers and sewn with Teflon yarn.
We have over four decades of experience in making filter fabrics and improving mill process productivity. Laboratory analyses of raw materials and finished goods play a very important part in Valmet’s operations. Our laboratory services include:

Valmet Disc Filter Bags are laser cut, so they are always identical in size. This simplifies installation and optimizes reliability and shrinkage.
