The base of the filter insert is the filtration medium in the form of special filtration papers made of glass sub-micron fibres.
This filtration paper is folded into a stable folded thread, whose optimal number and height of folds is in compliance with the operating point of the filter and ensures the required filter class and long lifespan of the filter insert. The paper is separated by hot melt (MACROPUR) beads or with separators made from aluminium foil (MACROPUR).
Filter thread is hermetically sealed into a stable, torsion-resistant filter frame and along with endless sealing from PUR foam it guarantees a high-quality sealing of the filter insert in the mounting cabinets. This filter structure is the base for compliance with high requirements for air purity. The basic frame is made of MDF. On request, it is also possible to make the filter frame from zinc-plated, stainless or aluminium metal sheets.
