Abstract
A louver assembly, which acts as a water-removing inertial separator, is located in the air intake of an enclosure maintained at negative pressure. The louver includes a number of spaced vanes, each formed without discontinuities by simple bending into a stair-step-like configuration when viewed end-on. Air enters the enclosure by passing between adjacent vanes, experiencing changes of direction of between 70 degrees and 90 degrees at the vane's surfaces to separate water therefrom.
