They are strong filtering cells at low-medium gravimetric efficiency and they are composed of a labyrinth structure filtering media having several knitted aluminum flat wire layers, kept by two zinc-plated wire nets and boxed into a galvanized steel frame.
They are used for fan-coil, air treatment units, warm air generators, ventilation equipment of machines, as pre-filters to filters with higher performances, as filters for hoods and drops separators.
The efficiency of these cells according to EN ISO 16890 is between ISO Coarse 35% and ISO Coarse 50% (between classes G2 and G3 according to EN 779:2012).
Better filtration characteristics can be obtained by varying the number of layers of metal mesh and, above all, by wetting the filter with adhesive oils.

They are disposable pleated filtering cells at medium gravimetric efficiency and they are composed of a nonwoven reinforced cotton fiber media supported on the air leaving side with a metal grid and boxed into a strong die cut cardboard frame. The pleating according to which the grid and media are fitted ensures a real filtering surface by two times (for filters having 23 mm thickness) to six times (for filters having 98 mm thickness) higher than the frontal surface of the cell.
They are used either as final filters or as pre-filters to filters having higher efficiency (like LOM-BAG pockets filters, V-cell filters or activated carbon filters) in ventilation and air treatment units, when it is necessary to combine good air flows with reduced passage sections.
These filters have an ISO Coarse 60% filtration efficiency according to EN ISO 16890 (G4 according to EN779:2012). The shape of the pleating ensures minimal resistance to airflow associated with a high accumulation of dust for the entire operating life of the filter.

They are pleated filtering cells with medium gravimetric efficiency, cheap but strong and they are composed of a self-extinguishing (F1 according to DIN 53438) synthetic fiber filtering media, kept by two zinc-plated wire nets and boxed into a 6/10 mm zinc-plated sheet frame. The pleating according to which the nets and media are fitted ensures a real filtering surface by two to three times higher than the frontal surface of the cell.
They are used either as final filters or as pre-filters to filters having higher efficiency (like LOM-BAG pockets filters, V-cell filters or activated carbon filters) in ventilation and air treatment units, when it is necessary to combine good air flows with reduced passage sections.
The CZ type cells are proposed with filtering mats with ISO Coarse 50% efficiency according to EN ISO 16890 (G3 according to EN 779:2012); those of type CZQ and CZS (characterized by a more resistant containment mesh) are instead built with ISO Coarse 60% efficiency mats (G4 according to EN 779:2012).
