Various new developments have been steadily increasing the performance of filter bag filtration in the recent past. These include fully welded bag filters or high performance needle felts. Increased filter surfaces through pleated elements or multi-layered constructions can also be used without
retrofitting. Thus the range of use has been considerably extended for you. The different filter bags are especially suited for nominal and absolute filtration in all kinds of metalworking, water purification, paints/lacquers, automotive and food industry.
The essential distinguishing feature of absolute filter bags compared to nominal types is the significantly higher deposition rate. They possess a much higher lifetime during the fine filtration of fluids. Increasing demands towards the deposition efficiency in order to improve the product quality or the compliance with limit values make their use inevitable in many cases. They are manufactured either as multi-layered or pleated variants.
