Product Details

• Electronic cleanroom passthrough with Smart® Control System provides advanced control and monitoring

• Obstruction free interior, lipless edges, radius corners, continuous welds for strict disinfection

• Quick and easy flush-mount design is hassle-free and installs in under 5 minutes (see video)

• Hidden electronic interlock allows only one door to open at a time to prevent cross-contamination

• Countless add-on capabilities: automatic doors, access security systems, UV disinfection, and more

• Cleanroom pass throughs reduce foot traffic, improve cleanliness, safety, productivity, and much more.

Chamber Design:

• Designed for sterile, regulated bio-pharmaceutical applications.

• Electronic door interlock allows for unique, custom door swing configurations such as 90 degree corners (L-shape chambers), 3-door designs (T-shape chambers), 4-door designs (X-shape chambers), and more.

• All-316L stainless steel surfaces with enhanced corrosion resistance stand up to harsher cleaning agents and withstand degradation from bleach-based disinfectants.

• Continuous welds with coved radius corners and lip-less edges eliminate hard-to-clean cracks and crevices where contaminants can collect.

• Double-wall construction greatly increases rigidity and durability of the pass through chamber to facilitate installation and prevent warping on larger chambers.

• Flush-mount design removes dust accumulating surfaces inside the cleanroom.

• Center-mount variation allows chamber to be centered in the cleanroom wall.

• Floor-mounted design includes removable ramps to support transfer of carts and heavy equipment between controlled spaces.

• Optional dual BioSafe® stainless steel racks easily remove for cleaning or sterilizing and are reversible to allow slide-out motion in either direction.

WARNING: Not suitable for biological applications.

Quick and Clean Installation:

• Innovative fastening system clamps to a variety of wall thicknesses without penetrating or damaging the finished surrounding wall.

• The mounting frame is covered on both sides for an easy-to-clean finish with no visible fasteners or screws.

• Easy-to-install mounting system also allows the entire passthrough chamber to be seamlessly removed and reinstalled within minutes, without damaging the surrounding wall.

Electronic Automatic Door Interlock:

• Hidden Smart® control panel is mounted outside the transfer chamber (between double-wall) for easy-to-clean obstruction-free chamber interior.

• Electronic interlock with Smart® Control System provides visual and audible door status alerts to prevent door damage that results when users exert excess force on an engaged interlock:

• Green light indicates both doors available for use.

• Red light and dual-side remote chimes indicate a door is open and interlock engaged.

Door Design:

• Access doors with 316L stainless steel reinforced frames extend passthrough chamber's service life and provide a tight seal.

• Doors include one-piece non-adhesive Santoprene® “e”-shape rubber gasket for tight seal to prevent outside air from leaking in; gaskets is non-outgassing and will not take a set or keep an impression.

• Doors are leak-rated by UL for tight seal to maintain cleanroom pressure gradients.

• Heavy-duty stainless steel lift latches included to minimize scratching, corrosion and contamination resulting over time that can occur with chrome-plated latches.

• Heavy-duty stainless steel detachable hinges allow doors to easily lift off for trouble-free replacement or more thorough cleaning/decontamination.

• Order replacement door(s) to avoid critical operation delays should a door be damaged and require immediate replacement.


• (1) Main power cord, to be hardwired to power supply onsite per local code by a licensed electrician.

• (1) Automatic electronic interlock.

• (2) Plug-in chimes (one for each side of the passthrough).

• Mounting bracket system with cover plates. Standard mounting system accommodates 4”-6” wall thickness. Specify wall thickness at time of order.

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

90° Corner Design

Custom door configurations are no problem. Install Smart pass-throughs in corner walls, with door swings in either direction.

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.
