The filter unit is essentially formed by the union of several modules that contain absolute filtration cells in class H13 or H14. The system is completely modular and configurable with the number of cells needed to ensure the cleanliness of the work area.

The equipment provides for the replacement of the filter elements in absolute safety through the safe-change system. In fact, maintenance operators will never come into contact with often highly toxic pollutants. The modules are joined together through the inlet and outlet plenums so that the air flow is distributed between the columns of the absolute filters. Since the dimensional development is reduced in depth, it is possible to insert this filter system in relatively small spaces.

On specific indications, the filtering groups or parts of them can be made of AISI304 (DIN17007, 1.4301) or AISI316 (DIN17007, 1.4401) stainless steel and equipped with ATEX.
