Porous metal filter elements
Introduction
Porous metal filter elements are manufactured in a broad range of materials and sizes.
Cleaning of porous metal filter elements using ultrasonic
To remove inert or insoluble solid from porous metal elements, ultrasonic cleaning is an most
effective process.
Evaluation of cleaning effectiveness
To evaluate the effectiveness of cleaning and the integrity of the porous metal filter elements. It is
necessary to flow test, and leak and/or bubble point test the elements after cleaning. For post–
cleaning evaluation to be meaningful, new elements should be serialized and „base lined“, with flow
and bubble point data recorded before they are put into service.
