Smart Pass-Through™ Chamber See how much more a pass-box can accomplish!
Turn your pass-though into an integrated part of your sample processing operation. The revolutionary Smart Pass-Through with electronic interlock monitors "blind-side" conditions and lets you mix and match performance-enhancing accessories, including operation alerts, access security controls, HEPA air shower or continuous air scrubber, UV-C sanitizer and refrigeration module.
Flush-mount design installs in less than five minutes and includes status alert logos: solid glow indicates chamber ready to access; flash indicates interlock is active or door left ajar (shown: No. 2635-10B-2).
Electro-magnetic interlock isolated outside the transfer chamber for easy chamber cleaning
Smart Control Module provides service alerts to operators on both sides
Doors lift off for easy cleaning and steriilizing

Signals when chamber is ready to load or unload with a continuous door alert light
Flush-mount design eliminates surfaces on “clean side” that collect germs and other contaminants
Easy installation allows the pass-through to be conveniently removed for servicing or upgrade without compromising the cleanroom environment - adjusts to any wall thickness >2"
Double-wall construction isolates the electronic interlock outside the transfer chamber for easy cleaning and sterilization of chamber interior
Provides power integration of all selected options: UV light, air shower, data logging, biometric security features and more

Flush-Mount System Allows Servicing or Replacement without Cleanroom Shutdown!
Terra's quick-mount system installs in under five minutes, regardless of wall thickness and without contamination
Inside of flush-mount bracket on opposing side
Bolt guide extending from nut welded to opposing bracket
Mounting bolt (one, two or three per side, depending on chamber height) - standard sizes accommodate any wall thicknesses
Standard wall (masonry or drywall)
The simplicity of the flush-mount 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.
Finish cut-out framing to minimize
contamination exposure during servicing
Service Alerts are wirelessly transmitted to remote plug-in chimes (remote data logging also available).
Smart Control Module: Guarantees Compliance with Operating Protocol
An interlocked pass-through is designed to prevent cross-contamination of a classified space. Situations like these, however, often thwart intended operation:
“Hello? Anyone there?”—Operators often have trouble alerting a colleague on the other side of the wall to unload the chamber.
“If it won’t open, force it!”—a door left ajar locks out the opposing side, frustrating an operator’s attempt to transfer materials. Worse, an operator may pull an interlocked door till it breaks!
“Power-cord spaghetti”—Smart Pass-Throughs provide a single power supply for many optional features, eliminating tangled cords.
It also provides a central point of power connection for accessories and triggers operation cycles.
Width = W (nominal) – 1.88"
Depth = D (nominal)* – 0.12"
Height = H (nominal) – 1.25"
Wall Cut-Out = W (nominal) + 2" x H (nominal) + 1.5"

Center-Mount Smart Pass-Throughs
Ideal for facilities that won't allow full chamber extension on one side or deep chambers that require center-wall support. Center-mount models include Terra's quick-mount system: installation in under 5 minutes!
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.

Fire-Rated Smart Pass-Through Panels The front panel of these models bears the UL 10B label for 90-minute fire exposure (suitable for 2-hour wall rating). The fire-rated door includes 2" of insulation and a paddle-style pull-latch. All models include viewing windows for convenient monitoring of pass-through contents, along with all the standard features of the Smart Pass-Through outlined above.

Automatic Door—for Hands-Free Operation
Ideal for pharmacy and medical applications, this door is activated by a touchless sensor pad to minimize contamination during sample transfer. Its quiet, low-energy, ADA-compliant electromechanical actuator is installed entirely outside the transfer chamber to simplify cleaning and prevent particle influx. Tested for over a million operations. Typical installation is on “clean” side. See operation video above!
Smart Pass-Through with Slide-Up Access Doors
These Smart Pass-Throughs feature dual counterweighted sliding doors that allow access to pass-through interior without the clearance requirements of a large swing door. The full-view static-dissipative PVC doors, mounted on stainless steel rails with counterweights for smooth, clean operation, provide complete visibility of chamber interior. The electro-magnetic interlock prevents both doors from opening at once, thereby preventing cross contamination. As soon as a door opens, the Smart Pass-Through alerts personnel on the opposing side that the interlock is active. On a custom basis, multiple chambers and even cleanroom doors can be interlocked to prevent more than one chamber or door at a time from opening. Select Access Control options below to monitor or restrict personnel access. Dimensions: 11.8"W x 19.7"D x 31.5"H (excluding hardware)
Materials: 304 Stainless Steel housing and door track; static-dissipative PVC doors
