网页2. Decide an appropriate pore size. The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test. • Nominal ratings are the pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%)
网页Filter Selection and Sizing Methods. • Select the filter material that is chemically compatible with the fluid to be filtered and that best fits your application. • Determine if you need a single-stage or multistage filtration train. For multi-stage filter systems, select the final filter first. Mulitstage filtration is necessary with
