BWF Envirotec Filter Bag Finishes
For Optimal Results in Air Pollution Control
All needlona® needle felts can be finished with a surface finish or protective treatment. This significantly improves service life, cleaning behavior, dust cake formation, and mechanical and chemical resistance. Protective treatment can be applied to all our product lines in many ways.
This anti-adhesive surface coating reduces the adhesive forces acting between the filter medium and the dust cake, improving cleaning properties and creating low Δp behavior in the filter system.
CS29
CS29® is a finish that provides excellent protection for the needle felt against acids, alkalis and hydrolysis. What’s more, CS29® features outstanding oil and water repellency.
CS52
CS52 is a protective finish against acid, alkali and hydrolysis for m-aramid filter media that repels dust, oil and water. An additional PTFE-based anti-adhesive finish improves dust separation properties.
CS17
CS17® is an oil- and water-repellent fibre impregnation that is based on fluorocarbon resin. It reduces the level of moisture that penetrates the needle felt, thus reducing the risk of excessive dust deposits and caking.
