Air filter cartridge ECOPLEN-F-G

for gasfinepolytetrafluoroethylene

EFP-400-G grades based on a porous film from polytetrafluoroethylene. The ECOPLEN-F-G filter elements are designed to remove particles of more than 0.2 μm in size from -20°C to + 150°C from gaseous media. Primarily used for dehumidification and final filtration of compressed air, nitrogen, carbon dioxide, highly aggressive media at normal and elevated temperatures, process steam used for processing equipment and also as respiratory filters. Construction and materials The filter material is a porous film of polytetrafluoroethylene (grade F-4, GOST 10007-80) without any additives or fillers. The filter material together with the external and internal drainage layers of thermally bonded polypropylene is laid in the form of a hollow cylindrical pleated package between the outer and inner perforated frames from polypropylene. Elements of height 500, 750 or 1000 mm are produced by welding 2, 3 or 4 elements with a height of 250 mm through the transition parts. Elements of any height can be manufactured both in a dead end and in the passage way. The end and transition parts, outer and inner perforated frames of the elements are made of monolithic polypropylene and hermetically welded to the ends of the pleated package. The particle retention efficiency is not less than 99.99% with the declared filtration rating and the recommended gas flow rate.
