Their solid structure and the filtering media, that can be regenerated several times, makes them particularly suitable in industrial processes providing high loads of dust. The relationship between the front surface and the filtering area is approx. doube in models 48 mm thick and approx triple in those 98 mm thick. During assembly special care is given to the inclusion of the filtering pack in order to make it integral with the frame to avoid possible dust passage.
