Special filtration papers, made of cellulose and glass sub-micron fibres with the required filter class, are used as a filter medium.
This filtration paper is folded into a stable thread with the optimum number and height of folds with respect to the operating point of the filter. Continuous hot-melt beads ensure not only stability of the thread, but also regular and parallel folds of the filtration medium and thus a full-scale use of the filtration area. Filter threads in a V-shape are sealed hermetically with a sealant into a stable plastic filter frame made of ABS. The peripheral clamping flange allows high-quality sealing of the filter insert in the mounting frame.
Filter inserts MULTIFORM can be mounted into common wall mounting frames, where sealing is glued.
Field of use
Filter inserts MULTIFORM are used mainly where maximum operating certainty and air purity is required. They are used for filtration of supplied air from fine dust, bacteria and pollens in all air-conditioning and ventilation devices or as a prefilter for highly efficient filter inserts.
