Standard Guide for Industrial Woven Wire Filter Cloth

Significance and Use

Industrial filter cloth is a specialized product that can be manufactured in many specifications. The purpose of this guide is to (1) introduce standard terms and definitions associated with wire filter cloth, (2) observe common technical considerations that a user should be aware of, and (3) present a mathematical model that can be used to predict the micron retention of a filter cloth specification. As often numerous specifications may be developed to result in a common micron retention by varying the weave type, mesh count, and wire diameters, it is recommended that the user consult with their filter cloth supplier regarding specific filter cloth specifications of interest and include in their discussions durability, pressure drop, and cleaning capability requirements. The purpose of this guide is not to suggest a limited selection of specifications.

The micron retention of a filter cloth specification can be mathematically modeled as well as determined by the use of a glass bead test or the bubble-point test method or both depending on the degree of fineness. Typical standard bubble-point test methods (porometry) include Test Methods F316 and SAE ARP901.

Abstract

E2814 covers the special grade of industrial woven wire cloth, referred to as filter cloth, for general filtration including the separation of solids from fluids (liquids or gases).

Filter cloth can be made of any primary metal or metal alloy wire that is suitable for weaving. There was no existing standard for filter cloth, which is a widely used material in industrial filtration.

The purpose of the guide is to introduce standard terms and definitions, observe common technical considerations that a user should be aware of, and to present a mathematical model that can be used to predict the micron retention or separation particle size of any filter cloth specification a user and producer wish to develop.

Scope

1.1 This guide covers the special grade of industrial woven wire cloth, referred to as filter cloth, for general filtration including the separation of solids from fluids (liquids or gases), based on a desired particle size retention. Filter cloth can be made of any primary metal or metal alloy wire that is suitable for weaving.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
