Flush-mount pass-throughs, including CleanMount CleanSeam and CleanMount BioSafe, can be installed and ready for operation in a few minutes once the wall cut-out is prepared. The unique integral bracket mounts the chamber flush against the cleanroom wall without the use of any external fasteners or the need for caulking. With no horizontal surfaces to collect dust, the chamber exterior helps maintain the most critical cleanroom requirements.
Fire-Rated and Ruggedized wall-mount pass-throughs can be installed and ready for operation in a few minutes once the wall cut-out is prepared. The process for contractors is straightforward, requiring the parts received from Terra, two people and the following additional supplies:
Fastener hardware appropriate for wall material (drywall or masonry, as examples). The number of fasteners needed will depend on the chamber size
Activated charcoal, the most common purification filtration medium, adsorbs chemicals with a molecular weight above 30 and a boiling point above 60°C. Carbon filters are also effective with many other chemicals because of their particular molecular structure.
Adsorption takes place in the active filter zone, the small cross-section of the filter bed in which the material to be removed comes in contact with the filtering medium (see illustration). This active filter zone moves upward as the filter becomes saturated. When it reaches the filter's top surface, there is an initial breakthrough by the contaminant gas; thereafter the percentage of contaminant gas that escapes filtration increases until total
