CleanMount™ Design Allows Servicing or Replacement without Cleanroom Shutdown!

passthrough replacement steps
Terra's quick-mount system installs in under five minutes, regardless of wall thickness and without contamination
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)

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.

  • Provides audible and visible alerts when the auto door interlock is active or door is left ajar to prevent forcing and potentially damaging locked doors
  • 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
  • Double-wall construction isolates the electronic interlock outside the transfer chamber for easy cleaning and sterilization of chamber interior
  • Provides a common power supply for all selected options: UV light, air shower, data logging, biometric security features and more
  • Includes two plug-in chimes for remote audible detection – up to 200 feet away – of door open/ajar status
  • 120V standard power supply (220V version 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 for till it breaks!

Service Alerts are wirelessly transmitted to remote plug-in chimes (remote data logging also available)
“Power-cord spaghetti”—Smart Passthroughs 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.

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!
