Filter Selection Based on Component Sensitivity Analysis

As a result of the advancement of two significant test procedures - the Multi-Pass Test for Filters and the Contaminant Sensitivity Test for Components, a totally new filter selection method has evolved. This method considers the severity of the application, the sensitivity of the components, and the particle capture capability of a filter. The paper introduces for the first time a filter selection chart concept which reveals the influence of operating pressure, contaminant ingression, and desired service life on the selection process. Emphasis is placed on user-oriented information, and the type of charts which component manufacturers could supply the user as well as the type of charts the filter manufacturer could supply are illustrated.
