Patent ID: 7582130

Claim:
A coalescing filter assembly to reduce liquid pooling therein, comprising: a coalescing filter having an upstream chamber and a downstream chamber, the coalescing filter adapted to filter a gaseous stream in a direction from the upstream chamber to the downstream chamber; and a weephole connecting the upstream chamber to the downstream chamber to enable liquid pooling in the upstream chamber to seep to the downstream chamber, wherein: said coalescing filter has a coalescing flow path therethrough from said upstream chamber to said downstream chamber; said weephole has a weephole flowpath therethrough from said upstream chamber to said downstream chamber in parallel with said coalescing flowpath; said gaseous stream flowing along said weephole flowpath does not flow through said coalescing filter along said coalescing flowpath; said gaseous stream flowing alone said coalescing flowpath passes from said upstream chamber through said coalescing filter to said downstream chamber without passing through said weephole; said gaseous stream flowing along said weephole flowpath passes from said upstream chamber through said weephole to said downstream chamber without passing through said coalescing filter.
