From several hundred different filter materials for the industrial dedusting industry, the following qualities were established over the years. The table shows the most important characteristics in an overview. For these qualities the following additional equipments are available: All filtering mediums are by default thermal-smoothed and calendered.
Further, high-grade steel fibers can be added for permanent deriving from static loadings. Complete impregnations with silicone as anti-adhesive protection against damp and sticky types of dust or with PTFE against chemical attacks can be realized as well. An admixture of fine fiber, purifying fiber or microfiber to achieve highest degrees of separation is also possible, as well as the use of inflammable fibers in order to increase flaming or spark protection.
