For sale is a BRAND NEW IN THE BOX DELPHI CURTAIN COOLING BLOWER FAN UNIT. The unit runs off 115V. The size is 28 1/2 inches long, 17 3/4 inches wide and 3 1/2 inches thick (all at their longest points). The power of this blower is strong. It moves alot of air. The unit can be mounted in a rack/cabinet. This fan is a government purchase and I bought the ones they did not use. I think they were used in the computer cabinets but they seem a little large for that.
