ABSTRACT:
A clean space system prevents pollution of clean surroundings in a processing space. Pollution is avoided which could otherwise occur when a worker comes in contact with the processing space while carrying out processes and operations in the clean surroundings. The apparatus includes a clean processing space, in which the processes and operations are carried out, and a preparing space coupled with an opening for work in the processing space. The preparing space is used by the worker prior to entering the processing space. In the preparing space, the worker performs preliminary actions such as changing his clothes and cleaning himself using an air shower to remove particles from his body.
