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. |

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT The invention generally provides a cleanroom conduit 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 has a perforated floor/bottom for exhausting air and contaminants out of the modular section.
Additionally, some of the modular sections have a filter attached to a wall for filtering incoming air that is being circulated 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.
These and other features, and advantages, will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.
It is important to point out that the illustrations may not necessarily be drawn to scale, and that there may be other embodiments of the present invention which are not specifically illustrated.
FIG.
1 illustrates, in a perspective view, a conduit modular section 30 in accordance with the present invention.
As illustrated, the conduit modular section 30 is a rectangular tube with four walls 12, 14, 16 & 18' and two open ends 20, creating a chamber.
Each wall is constructed with a transparent material for easy viewing into the chamber.
Examples of suitable materials include a rigid polycarbonate, such as Lexan.
TM.
, and glass.
Using a polycarbonate for the sidewalls has an advantage of making the modular section lightweight.
Although not specifically illustrated, one or more of the walls may include doors for easy access into the chamber.
The frame of each modular section may be constructed from, but is in no way limited to, aluminum, painted steel, or polished stainless steel.
Additionally, the modular section 30 has in one of its walls 18', other than the bottom wall 12, an opening 32 for supplying a gas into the chamber
