ABSTRACT:
A method and apparatus for drying floors and carpets using a fan for generating a pressurized air stream within a vertical cylindrical shroud that is spaced two to five inches away from the floor on a set of legs such that an opening is formed between the shroud and the floor. The air stream is directed along the cylindrical shroud vertically toward the floor. At least a peripheral portion of the air stream is exhausted from the shroud in a substantially laminar flow at an angle that is inclined from the vertical and is exhausted radially into ambient air as a substantially laminar air stream.
