    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.

Features and Benefits

Interlock Status Lights

Red light indicates opposing door is open (interlock engaged); green light means door available for use.

CleanMount™ Quick Install System

Clean-Mount™ design allows pass-through installation flush against the cleanroom wall in a few minutes, without screwing into the wall; mounting brackets clamp flush against walls of any thickness.

Transparent Door

Transparent pass through doors with clear acrylic and static dissipative PVC options are offered in these ValuLine Pass Throughs. Compression latch and steel reinforcements provides stability to the pass-through door.

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.

Flush-Mount Design Prevents Dust Accumulation

CleanMount® pass-throughs hug the cleanroom wall, eliminating gaps that collect germs and particle and making them ideal for critical bio/pharmaceutical cleanroom use.

Stainless Steel-Reinforced Removable Pass-Through Door

The stainless steel-reinforced CleanMount® doors lift off for easy replacement or more thorough cleaning/decontamination.

CleanMount® Isolated Interlock Simplifies Cleaning!

Double-wall construction allows interlock installation outside of the main transfer chamber, leaving unobstructed, smooth interior surfaces that wipe down easily - ideal for critical bio/pharmaceutical processing.

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.

UV Sanitizing Module

Neutralizes bacteria, viruses and mold spores inside the pass-through chamber (available on select models).
