Abstract
A method and apparatus for drying floors and carpets using a louvered grille with a shrouded floor drying 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. By means of the louvered grille 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 the air stream is exhausted radially into ambient air as a substantially laminar air stream.
