Newest Design PHFZ Series Pleated Filter Cartridge

 PHFZ Series washable pleated filter cartridge is currently the most widely used Condensate Polishing pre-filter cartridge in domestic. It’s made of pleated high-precision polypropylene filter membrane, all welded using hot-melt, without any additives, adhesives and surfactants, which ensure high accuracy, high-throughput, high-strength, low extractables and low initial pressure. It can be divided into PHFZ-Ⅰ(7 parts), PHFZ-Ⅱ(2 parts) and PHFZ-Ⅲ (4 parts) three types. The PHFZ-Ⅱ (2 parts) is welded of 40 " and 30 ", is the only one filter with 69mm diameter and integral outer support in domestic.

Features And Benefits
