Needlefelts are constructed for optimum abrasion resistance, they are made from selected synthetic fibres. The fibres are arranged in a homogeneous web prior to needling.
In dry filtration and dust collection the felt is designed to produce maximum toughness (energy to rupture) and flex resistance (minimum stiffness) to give prolonged operating life. Extended life also results from control of pore size and permeability, thus avoiding premature blinding.
Various finishing processes are designed to give the required dimensional stability, strength, permeability, porosity and surface finish.
EFS can provide all needlefelt filter bags for all the industrial markets in all types of medias. Our expertise in coated materials and knowledge of membrane surface filtration provides you with the solutions to keep equipment running efficiently.
