Pass-Through Basics

General Use 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.

Shutting the Door on Contamination
These Pass-Through Chambers cut down significantly on traffic and contamination by providing a better, safer way to transfer equipment and paperwork.

304 Stainless steel or powder-coated steel pass-throughs ensure clean operation. For especially stringent particle requirements, select an UltraClean™ electropolished 304 stainless steel pass-through.

Polypropylene and PVC models are suitable for chemical pass-through applications, and Static-Dissipative PVC models combine excellent chemical resistance with a surface resistivity of about 107ohms/square for enhanced static and particle control. Each model features viewing windows of a compatible material.

Doors on either side are outfitted with an automatic mechanical interlock that allows only one door at a time to open. The no-maintenance interlock has no power, gas, or other facility requirement, so it continues to operate when other systems shut down. It engages at the same time the latch is lifted to open the door; no additional hands-on manual steps are required.

Access Clearances
Width = W (nominal) – 1.88”
Depth = D (nominal)* – 0.12”
Height = H (nominal) – 1.25”
* Subtract 0.5” for plastic chambers. Each door adds 0.5” to nominal depth.
Standard Pass-Through Mounting
All models include mounting brackets (stainless or powder-coated steel) and required hardware. Mounting brackets require 0.25” (6 mm) clearance between the wall cut-out and the pass-through. Standard mounting is 2” (51 mm) from the front of the cleanroom side (specify other desired location).
Wall Cut-Out = W (nominal) +0.5” x H (nominal) + 0.5”
Pass-Through Chamber Support Brackets
Order optional support brackets for wall-mount pass-through chambers that are 36"D or larger. They support the weight of the pass-through, and are designed to allow chambers to protrude 2" (51mm) on the cleanroom side. Indicate other desired position when ordering.

Pass-Through Chamber Interlock

Terra’s automatic mechanical interlock prevents cross-contamination by allowing one door to be open at a time. Encased in stainless steel, the mechanism is rated for millions of operations, more than enough to last the lifetime of the pass-through.

Stainless Steel Pass-Through LiftLatch™

Terra’s unique LiftLatches™ use leverage to apply force in a gentle, controlled manner, eliminating rotary motion used on other latches that strain wrists and door hinges. The LiftLatch snaps into place to produce a positive seal.

Stainless Steel Reinforced Doors and Handle

Doors on professional-grade pass-through chambers are reinforced with stainless steel frames, which lend rigidity, improve the seal, and extend the service life of the doors.

One Piece Elastomer Gasket Illustration

The white, “e”-shaped gasket provides a flexible seal that will not creep or deform over time. The gasket is made of a non-outgassing, thermoplastic elastomer that is resistant to harsh chemicals and extreme temperatures.

  • 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.
  • CleanTop™
    The CleanTop™ is designed for installations that require the chamber to be centered in the wall. The 30° sloping top on the cleanroom-side minimizes particle accumulation and accommodates laminar downward airflow.
  • Passthrough Chamber Door Stop
    This stainless steel door stop limits the arc of the pass-through door's swing to 90°, preventing damage to wall, door latch and other components. Door stops can be adjusted to allow other angles.
  • 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.
  • Grounding Terminals
    Grounding terminals are ideal for the most static-sensitive applications (must be ordered with chamber; cannot be retrofitted).
