Global Filter's All Fluoropolymer GPFA Series
PTFE membranes provide high flow rates with low pressure loss! They minimize the extraction of ions and TOC.
The "GPFA Series" is a high-purity all-fluoropolymer filter cartridge suitable for aggressive "wet etching and clean" applications. To meet the more demanding needs of the microelectronics industry, it offers ultra-low extractables along with excellent chemical compatibility and temperature range. The PFE-440HP hardware demonstrates excellent chemical resistance and high-temperature tolerance, while the PTFE membrane provides high flow rates with low pressure loss. 【Features】 ■ Suitable for "wet etching and clean" applications ■ Addresses the more demanding needs of the microelectronics industry ■ Offers excellent chemical compatibility and temperature range ■ Wet pack options available ■ Available in a full range of filtration options suitable for all applications *For more details, please refer to the PDF materials or feel free to contact us.
