  • Door Design:
  • Access doors with 316 stainless steel hinges extend passthrough chamber's service life and provide a tight seal.

CleanMount BioSafe Smart Pass-Through Chamber

Don't risk operational delays or cleanroom shutdown because of a damaged door!
Terra's pass-through chambers last indefinitely, much longer than our standard product revision cycle. Pass-Through doors, however, are subject to damage, and ordering a legacy replacement can be costly and disrupt cleanroom operation. To avoid these problems, order replacements at the time you purchase the pass-through chamber; simply add “-RH” (for right-side hinge) or “-LH” (for left-side hinge) to the part number of the chamber.
CleanMount™ Design Allows Servicing or Replacement without Cleanroom Shutdown!
The simplicity of this CleanMount clamping system makes removal of the pass-through chamber just as easy as installation. If the wall cut-out framing is properly sealed prior to installation, the pass-through can be quickly removed and replaced without ever having to shut down the cleanroom. Maintain the positive-pressure differential and protect the cleanroom environment by sealing off the "dirty side" with plastic sheeting prior to removal. Loosen the lag bolt so that the pass-through lifts out of the wall without contaminating the room. Once out, the pass-through can be serviced, modified, or even replaced with an upgraded version to accommodate new applications.
A - Inside of flush-mount bracket on opposing side
B - Bolt guide extending from nut welded to opposing bracket
C - Mounting bolt (one, two or three per side, depending on chamber height) - standard sizes accommodate any wall thicknesses
D - Mounting bracket
E - Bracket cover
F - Standard wall (masonry or drywall)
Finish cut-out framing to minimize contamination exposure during servicing Terra's quick-mount system installs in under five minutes, regardless of wall thickness and without contamination

BioSafe® CleanMount Pass-Through Locking Mechanism

The BioSafe® pass-through's door catch mechanism connects to an automatic internal interlock that prevents both doors from opening simultaneously.

316 Grade Stainless Steel Pass-Through Hardware

The hinges, catcher, and latch bar are all composed of 316 stainless steel for maximum cleanliness. The hinges and handle are also removable to enable for easy door cleaning.

Removable Autoclavable Silicone Gaskets

The one-piece silicone gasket on each door is mounted onto the pass-through by only a few screws per edge, making removal and cleaning simple and easy.

Sloped Top BioSafe® CleanMount Pass-Through

The sloped top design minimizes particle buildup, promoting a cleaner, more sanitary workspace. It also simplifies cleaning, improving overall efficiency.

Durable Double Wall Construction

BioSafe double-wall construction triples unit lifespan and totally eliminates cleaning of accessories

Easy Installation Simplifies Cleanroom Commissioning

Installing conventional passthroughs can be very messy, making it impossible to perform while a cleanroom is operational. Terra’s innovative CleanMount® fastening system changes that, allowing for clean installation without drilling or penetrating the cleanroom wall. Framing a CleanMount® passthrough chamber on a finished cut-out eliminates the need for cleanroom shut-down during installation or service.

CleanMount® Lipless Chamber Eliminates Clearance Obstructions

Instead of welded seams, the corners of the CleanMount® pass-through interior are coved to eliminate dust and germ traps. The lipless opening presents no clearance obstructions and further simplifies cleaning.

Terra’s comprehensive product portfolio includes solutions for every application and budget. Our technical sales staff will guide you toward the product most suitable for your requirements.

Products Tailored to Your Cleanroom Environment

  • Pass Through Racks

    Designed to be installed into any pass through. Install these racks within minutes with no special tools. Simply tighten a compression screw. Forgot to order racks before? No problem!
  • Passthrough Ventilation Exhaust Ducts

    Adding a duct flange to the top of the passthrough allows the chamber to be ventilated by a remote blower. The ULPA-filtered inlet, housed in a perforated stainless steel cage, provides the necessary make-up air without contaminating the chamber.
  • Grounding Terminals

    Grounding terminals are ideal for the most static-sensitive applications (must be ordered with chamber; cannot be retrofitted).
  • Mounting System for Tempered Glass Wall Panels

    This unique mounting system allows installation of pass-through chambers on Terra Universal's modular cleanrooms with tempered glass wall panels.
  • ULPA-Filtered Air Shower

    High-velocity, ULPA-filtered air dislodges surface-deposited contaminants and exits the chamber through a filtered exhaust.
  • ULPA Exhaust Port

    ULPA exit filter module captures and removes residual particles between cycles to preserve cleanroom integrity at every transfer.
  • Support Brackets for Pass-Through Chambers

    Stainless steel support brackets are recommended for pass-throughs deeper than 24". Brackets fasten to the wall and the body of the chamber rests upon the horizontal bar; no fasteners are used on the pass-through itself.
