ABSTRACT:
A cleanroom conduit (44) is used for transporting products between two cleanroom environments through an area that is less clean than either cleanroom environments. The conduit is modular in nature and thus can be adapted for various distances between the two cleanrooms. Each modular section (10 & 30) has a perforated floor (12) for exhausting gas and contaminants out of the modular section. Additionally, each modular section (30) has a filter (38) attached to a wall, with an opening therein, for filtering the incoming gas that is being supplied recirculated through the conduit. In effect, the conduit is maintained as a mini-cleanroom such that products being moved from the first cleanroom through the conduit do not require a decontamination step before they can be reintroduced into the second cleanroom.
