Description
Pretreat Filter-S(PTF-S) is well suited for ultra high purity DI water applications where very fine removal ratings are required, together with extremely high flow rates, for economical installations. It contains a highly asymmetric polysulfone membrane that results in exceptionally low pressure drop values.
► Available in removal ratings from 0.02 pm to 0.45 pm
► Double layer, patented highly asymmetric polysulfone membrane
► Rapid rinse-up
► Integrity testable
► Manufactured in cleanroom environment
