CleanMount Basics

CleanMount CleanSeam Pass-Through 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

Interlock Status Lights

A green light bar indicates the door is available for use, with the electronic interlock disengaged. The bar turns red when the opposing door is open to indicate the electronic interlock is engaged.

Wireless Door Alert

Alarm bell rings when its assigned door is open (two bells per chamber); plugs into a standard wall outlet.

CleanMount™ Quick Install System

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

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.

Rerigerated Pass-through Chamber

The interior of the Refrigerated Smart Pass-through includes a ceiling-mounted fan unit that distributes the conditioned air from the condenser above. A drain tube is ported through the wall to carry condensation outside of the transfer chamber.

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® 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.
