Abstract
This low-profile filtration module has a blower partially occupying an equalization chamber above a standard filter unit. A diffuser plate is interposed between the filter and the equalization chamber, and has a plurality of openings elongated in a direction perpendicular to the planes of the filter pleats. The density of the openings is increased at the portions of the equalization chamber where the space for lateral air flow is decreased by the presence of the blower.
