Features and Benefits

CleanMount Basics

CleanMount Smart 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.
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

Removable Cart Ramps on Floor-Mount Models

Floor-mount pass-through chambers include dual-side stainless steel cart ramps, sloped on three sides, that are removable for easy cleaning.

Interlock Status Lights

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

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™ 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.

Smart Biosafe® Pass-Through Electronic Door Interlock

Smart Biosafe® Pass-Throughs include visible/audible door status alerts: red light and chimes indicate opposing door open (interlock engaged); green light means door available for use. Smart add-ons expand capabilties: LED/UV light, access control, air shower, more!

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.
