A filter housing for retaining a roomside replaceable filter is generally provided. In one embodiment, the filter housing includes one or more sidewalls defining an interior volume. Each sidewall includes a first section and an adjacent second section sealingly coupled thereto. A sealing member is coupled to the second section and extends into the interior volume. The sealing member adapted to provide a gas-tight seal between with a replaceable filter. A hole is disposed through at least one of the first or second sections. The first section is sealed to the second section around a perimeter of the hole.

1. Field of the Invention
The embodiments of the present invention relate generally to a filter housing.
2. Background of the Invention
A more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof that are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and, therefore, are not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.
FIG. 1 depicts a simplified, partial sectional view of one embodiment of a filter housing having a filter retained therein mounted in a ceiling;
FIG. 2 is an alternative embodiment of a sealing section of a filter housing;
To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures.
FIG. 1 depicts a sectional view of one embodiment of a filter module 100 disposed in a ceiling 102 of a cleanroom 104. Typically, additional filter modules 100 (not shown) are utilized in predetermined positions within the cleanroom 104 to provide predetermined levels of cleanliness and ventilation. The filter module 100 generally includes filter housing 106 that retains a removable filter 108. The scale of FIG. 1 has been exaggerated for clarification of the interface between the housing 106 and the filter 108. The filter housing 106 includes a plurality of sidewalls 110 and a backplate 112 that define an interior volume 114. It is also contemplated that cylindrical housings may utilize a single sidewall 110.
The backplate 112 includes a collar 116 to facilitate coupling the filter housing 106 to a duct 118 that supplies air from an air handler 120. The air handler 120 provides flow control of the air provided to the filter module 100. The air handler 120 includes one or more blowers or fans (not shown) and may additionally include pre-filtration elements such as ASHRAE or HEPA filters.
