Abstract
A coalescing filter assembly having an upstream chamber, a downstream chamber, and a weephole connecting the upstream chamber to the downstream chamber. The downstream chamber includes a coalescing filter to filter a flow of gases. A passageway may be implemented between the upstream chamber and the downstream chamber to accommodate the flow of gases therethrough, while the weephole enables liquid to seep from the upstream chamber to the downstream chamber. In this manner, the weephole reduces liquid pooling in the upstream chamber without substantially compromising the efficiency or performance of the coalescing filter. A drain may connect to the downstream chamber to drain liquid collected therein.
