Clean room and method

摘要

A clean room which avoids the problems attendant with the raised floor found in prior art clean rooms uses a perforated floor upon which equipment can be directly placed. The perforated floor includes a regular array of openings through which air can pass to an underlying facility room. The openings are covered by a grate through which the air can pass. In combination the perforated floor and the grates are able to support equipment in any location thereon.
