Abstract: An air transferring system is disclosed. The air transferring system includes an enclosure, a faceplate, and a blower assembly attached to the faceplate. The enclosure includes a base, a lid having an air exhaust, and a shroud. The shroud has an open shroud top, an open shroud bottom, and an opening in the shroud defined between a first shroud edge and a second shroud edge. Each of the shroud edges extends between the open shroud top and the shroud bottom. The faceplate includes a faceplate opening that extends between the first and second shroud edges. The blower assembly includes a blower exhaust proximate to all of the faceplate opening, an exhaust opening, and an impeller for drawing air through the air exhaust, faceplate opening, and blower exhaust and urging the air out the exhaust.
