Patent ID: 6916352

Claim:
A method of preventing air bypass in a filter bank, the method comprising of the steps of: providing a filter bank having a filter track, consisting of parallel spaced tracks, which receives filter in side by side abutting relation inserted through an access opening; providing a plurality of rectangular filter panels, each filter panel having an opposed pair of first sides, an opposed pair of second sides, two opposed faces, and a width between the two opposed faces; providing “I” shaped connectors, that are discrete from the filter bank, having a length substantially the same as the length of the opposed pair of second sides of the filter panels and opposed channels having an inner dimension substantially equal to the width of the filter panels; and inserting the filter panels through the access opening into the filter bank with the first sides of each filter engaging the filter tracks and sequentially connecting the filter panels in side by side relation with the “I” shaped connectors by placing the second sides of abutting filter panels into the opposed channels of the “I” shaped connectors, such that the positioning of the “I” shaped connector prevents air bypass between the second sides of adjacent filter panels.
