Abstract From the Canadian patent

High Performance Water Collector A high performance water collector (1) dries a moisture-laden airstream within a duct (7) by providing an air guide (20) within a gap (12) between a collector inlet section (4) and discharge section (6). The guide (20) defines a scupper (26) to direct the heavily moisture-laden air to a diffuser (14) surrounding the gap (12). The diffuser (14) slows the air, causing the water to fall naturally within the diffuser (14) for subsequent removal. The guide (20) further defines an ejector (28) for infusing the dried air back into the duct.
