Small pore membrane filters are used inthe filter. Membrane filters are thin ( in. thick) porus structures composed ofpolymeric materials. These filter elements have uniform pore size for good surfaceretention of :SAMPLING SYSTEM AND ANALYZER MAINTENANCE IS REDUCEDUSES MEMBRANE FILTER ELEMENTS FOR SURFACE FILTRATIONTANGENTAL ENTRY OF BYPASS CREATES SWIRLING ACTIONKEEPS FILTER ELEMENTS CLEAN - PARTICLES ARE RETURNED TO PROCESSIDEAL FOR CONTROL APPLICATION.

3 Replace those existing filters that have atendency to plug shortly after being placed in service. The Collins Swirlklean is even recommendedfor dirty streams containing iron sulfide, iron rust, catalyst and other fine particles. Standard filterelements have a micron pore size. Other pore sizes are the Collins Swirlklean in your next analyzer installation for cleaner samples and moretrouble-free : The Collins Swirlklean bypass filter alone is notrecommended for filtering water.
