EXafPure WF Series -All PTFE Filters with Ultra-high Cleanliness
Membrane Solutions ExafPure WF series filters are All-PTFE structure. The filters use high flow rate PTFE membranes. This kind of filters is especially designed for chemicals including SC1, SC2, 49HF, HNO3, EKC and NMP in SEMI-WEC application.
Excellent filter design could ensure low pressure drop across the filter and good particle removal performance. The fluoropolymer material possesses low concentration of extractables and other contaminants that may be detrimental to the process, and provides high retention performance in the application at the same time.
