Axial Flow Filter Cartridge

This filter cartridge is designed for easy replacement in the housing of a data processor by a customer engineer as a part of regular maintenance service. The filter is intended to provide a maximum of filtering performance with a minimum interference with the air flow.

As shown in the inset blowup view, a layer 1 of weak filter material is supported between two layers 2 of an open pore foam and is held in place by thin glue lines at the sides. The composite filter layer 3 is folded vertically in accordion pleats into a block slightly larger than the final shape of the filter cartridge. This block is cut into shape along the open sides. the open sides are coated with a sealing coat 5 of an adhesive material and a thin layer 4 of a closed cell foam sheet is secured to close off the open ends. Another layer of the adhesive on the material and extends above the filter material.

In operation, this assembled filter cartridge is placed into a filter housing 8 and the upper extension of sleeve 6 is folded down over the outside of the housing. A closure fitting over the turned down edge of sleeve 6 will complete the seal of the filter to close off any air leakage around the cartridge.
