METHOD OF FABRICATING AIR FILTERS

摘要

High efficiency air filters are fabricated by forming two end assemblies from rectangular wall members with side plates attached to extend upwardly from opposite sides thereof. A removable wall of expendable material such as ordinary masking tape is applied to the other two sides, extending between the ends of the side plates to form a shallow pan which is filled with a liquid adhesive. The pleated filter media is attached along its two side edges to side wall members having notched ends for mating with the side plates of the end assemblies. One edge of the filter media between the two side walls is immersed in the pool of adhesive and the side walls are attached to the side plates. After the adhesive hardens, the masking tape is removed and the other end assembly is attached in the same manner.
