A clean room has an equipment installation area where an apparatus for treating an object to be treated such as a semiconductor wafer is installed, a process area 4 where the object is loaded in or unloaded from the apparatus, and an operation area where operations of the apparatus are executed. The equipment installation area, the process area and the operation area are arranged horizontally in the above-stated order and separated by partitions. These areas are air-conditioned independently of one another. The clean room is thus capable of preventing contamination of the object and a running cost of chemical filters in the clean room is reduced.

A system for providing and managing a laminar flow of filtered air for a clean room workspace has a blower for blowing air through a filter and over the work area. The velocity of air flowing through the filter is automatically controlled by a feedback loop wherein sensors enable the system to learn of a drop in flow, or even a flow rate that strays above a set point, and to then take action to change settings of the variable frequency drive which, in turn, vary the current to the motors causing a change in blower speed. The system's programmable logic control also provides for automatic recording and storing of data relating to the operating characteristics of the system, including the date and time that the operating characteristics were recorded. The recording may be done in a manner so as not to be editable by the system operator, which makes such record compliant with federal regulations.
