DISPOSABLE FILTER ELEMENTS

Elements are specifically designed for the removal of liquid aerosols and particulate from gases in both corrosive and non-corrosive applications.  The C type element is constructed of two layers of borosilicate microfiber.  The first (inner layer) is comprised of very fine fiber and is more densely packed to capture microscopic aerosols.  The outer layer is made up of slightly larger fibers which allow the csaptured liquids to pass through the depth of the wall and drain off the filter element.  This two-layer design is critical to proper coalescing, and borosilicate microfiber is best suited for this function.  Coalescing elements should always flow from the inside to the outside of the element so that proper draining of liquids can occur.  The C grade elements will simultaneously collect particulates.   

Elements are specified for particulate removal where corrosive gases are to be filtered as they have excellent chemical resistance.  They are also used when highly reactive gases are being analyzed since they exhibit very low levels of adsorption.  The borosilicate microfiber provides relatively high flow rates with low pressure drops which is critical in any analytical application.  The PVDF binder creates a non-reactive surface which allows accurate sample analysis.
