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.
