Air Filter Face Guards and Mesh

Filtration Table of Contents

To guard against damage from careless handling and faulty installation procedures, a recessed faceguard should be installed or designed across both faces of the filter during fabrication.

Woven or expanded metal with square openings approximating 1/3 inch to 1/2 inch on a side have proven satisfactory in largely preventing the inadvertent intrusion of hands or other objects into the air filter pack. In addition, a metal mesh faceguard provides added strength to the filter unit, increasing resistance to transportation damage and shock overpressure.
