Abstract

A method of preventing air bypass in a filter bank and a filter assembly in accordance with the teachings of the method. Filter panels are inserted through an access opening of a filter bank. As the filter panels are inserted they are connected in side by side relation with “I” shaped connectors. The sides of adjoining filter panels are inserted into opposed channels of the “I” shaped connectors. The positioning of the “I” shaped connector prevents air bypass between the sides of adjacent filter panels.

Claims

1. 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.

3. The method as defined in claim 1, further comprising the step of providing only a single side access opening as the access opening.

2. A filter assembly, comprising:

a filter bank having a filter track, consisting of parallel spaced tracks, which is adapted to receive more than one filter arranged in side by side abutting relation through an access opening;

rectangular filter panels, each of the filter panels having an opposed pair of first sides, an opposed pair of second sides, two opposed faces, and a width between the opposed faces;

“

I”

shaped connectors, 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

the first sides of the filter panels engaging the filter tracks and the filter panels being connected in side by side relation with the “

I”

shaped connectors with the second sides of abutting filter panels in the opposed channels of the “

I”

shaped connectors, such filter the positioning of the “

I”

shaped connector prevents air bypass between the sides of adjacent filter panels.

4. The filter assembly as defined in claim 2, wherein the access opening is a single side access opening.

5. 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 apart tracks for receiving at least two sequential arranged and closely adjacent filter panels via an access opening in the filter bank;

providing two filter panels with each of the two filter panels having a pair of opposed first sides, a pair of opposed second sides, a pair of opposed faces, a height defined by a distance between the pair of opposed first sides and a width defined a distance between the pair of opposed faces;

providing at least one “

I”

shaped connector which is separated and discrete from the filter bank, the at least one “

I”

shaped connector having a length substantially equal to the height of the two filter panels and having a pair of opposed channels with suitable for receiving one of the second sides of the two filter panels and an internal width dimension substantially equal to the width of each of the two filter panels;

sequentially inserting the two filter panels through the access opening, one after the other, such that the first sides of each sequentially inserted filter panel engages with and are guided along with the filter track; and

inserting the “

I”

shaped connector between the second sides of the two sequentially inserted and adjacent filter panels such that each one of the pair of opposed channels at the “

I”

shaped connector receives one of the second sides of the two filter panels and, during operation of the filter bank, the “

I”

shaped connector, restricts air from bypassing between the second sides of the two adjacent filter panels.
