Description
1.0
Terra Universal Pass-Through Chambers allow room-to-room transfer of materials and samples without contamination. The
modular-panel mounting system allows installation on any wall type (such as wood or masonry) and thickness, and keeps
particle counts low by eliminating unnecessary room entry by personnel.
All cleanroom pass-throughs include a mechanical interlock system that minimizes the risk of cross-contamination. This device
allows only one open door at a time, thus minimizing the amount of “dirty” air that can enter the cleanroom. General-use pass-
throughs utilize a chamber-mounted interlock (also called a single-wall design). An isolated interlock (or double-wall design)
simplifies cleaning and eliminates cracks that can harbor contaminants, making it ideal for the life sciences and clinical
applications.
CleanMount® System
The CleanMount® System (featured on select pass-throughs) utilizes a clamping mechanism to allow the pass-through to be
installed without any fasteners piercing the wall surface. This design enables quick installation with minimal impact on any
high-grade finished surfaces, and a significant reduction in debris and airborne particulates. When making the wall cut-out for
this type of pass-through, installers now have the option of finishing and sealing the cut-out with a cleanroom-grade surface.
That way, if the pass-through must be removed at a later date, the CleanMount® System will disassemble quickly and cleanly
while the cleanroom can remain in operation.
Installation
2.0
CAUTION
The installer is responsible for ensuring all of the following:
•
All sides of the wall cut-out must be flat and level within a tolerance of 1/16” for every 36”.
•
If the pass-through will be floor-mounted, the floor underneath and surrounding the pass-
through must also be flat and level within a tolerance of 1/16” for every 36”.
•
If the pass-through includes optional components that have been preinstalled, such as an
exhaust flange or ULPA filter housing, these must be removed prior to installation (See
Section
6.0 Optional Pass-Through Features
).
Failure to comply with any of the instructions contained in this manual can result in damage to the unit
or improper installation, rendering the pass-through inoperable.
