Several layers of woven mesh are sintered together to form an integrated, porous filter medium. Coarse meshes support a drainage mesh overlaid by the accurately woven filtration mesh, which is in turn protected from mechanical damage by a further layer.
This is a surface filtration medium. Particles are held on the outer layer, making cleaning by jetting or backflushing highly effective. This material has good mechanical strength, and can be cut, rolled, welded and machined.
The sintering process bonds every wire to its neighbours, eliminating the problems of fibre migration in critical applications. The open structure gives considerably lower pressure drops than sintered metal powders.
As well as the standard range, special batches can be made with additional layers or in other alloys, such as Hastelloy®.
