Product Details
Product Details
  • Available ISO Ratings: ISO 5, ISO 6, ISO 7, ISO 8
  • Easy-to-sterilize 316L stainless steel cleanroom pass through for sterile bio-pharma applications
  • Obstruction free interior, lipless edges, radius corners, continuous welds for strict disinfection
  • CleanMount design allows for installation without drilling and prevents cleanroom shutdown for rapid servicing or replacement
  • Hidden automatic door interlock allows only one door to open at a time to prevent cross-contamination
  • Lift-off hinges allow doors to be easily removed for more thorough cleaning
  • Cleanroom pass throughs reduce foot traffic, improve cleanliness, safety, productivity, and much more.
  • Chamber Design:
  • All 304 or 316 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.
  • 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.
  • Hidden Automatic Door Interlock:
  • Hidden Interlock mechanism is mounted outside the transfer chamber (between double-wall) for easy-to-clean obstruction-free chamber interior.
  • Rugged and reliable CleanMount® mechanical interlock uses rigid stainless steel rods that run through the door and firmly lock into the lift latches.
  • Door Design:
  • Access doors with 304 or 316 stainless steel reinforced frames extend passthrough chamber's service life and provide a tight seal.
  • Santoprene® “e”-shape non-outgassing rubber gasket firmly compresses to eliminate leaks. The one-piece resilient rubber gasket maintains its shape after compression and won't flatten, warp, crack, or degrade like ordinary foam gasket. Gasket is also mechanically attached to the door frame to avoid adhesive failure common with gasket tapes.
  • Doors are leak-rated by UL for tight seal to maintain cleanroom pressure gradients.
  • Heavy-duty stainless steel lift latches minimize scratching, corrosion and contamination resulting over time that can occur with chrome-plated latches.
  • Sturdy "lift-off" stainless steel hinges are welded to the door frame and chamber. They are detachable to allow doors to easily lift off for more thorough cleaning/decontamination or trouble-free replacement.
  • Order replacement door(s) to avoid critical operation delays should a door be damaged and require immediate replacement.
  • Includes:
  • (1) Automatic mechanical interlock.
  • Mounting bracket system with cover plates. Standard mounting system accommodates 4”-6” wall thickness. Specify wall thickness at time of order.

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

Critical Environment Solutions

Terra's mission is to help customers in highly regulated industries transform the world with critical environment solutions that improve health, safety, performance, and yields. These environments may comply with stringent UL, ISO, IEST, ASTM and OSHA standards and local requirements.

Lift-Off, Non-Shedding Door Hinges

Non-shedding, barrel-type door hinges allow the doors to lift off for thorough cleaning and decontamination (no tools required). Unlike industry standard continuous designs, these hinges comply with strict ISO levels.

Durable Double Wall Construction

BioSafe double-wall construction triples unit lifespan and totally eliminates cleaning of accessories

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.

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.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields.

  • Pass Through Racks

    Designed to be installed into any pass through. Install these racks within minutes with no special tools. Simply tighten a compression screw. Forgot to order racks before? No problem!
  • Interlock Status Lights

    Prevent operator damage! 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.
  • LED Recessed Light

    Activates when either pass-through door opens; flush with the wall surface, covered by a static-dissipative PVC lens.
  • UV Sanitizing Module

    Provides a timed cycle of 254 nm Ultra-Violet (UV) radiation to neutralize bacteria, viruses and mold spores within line-of-sight of the light fixture.
  • ULPA-Filtered Air Shower

    High-velocity, ULPA-filtered air dislodges surface-deposited contaminants and exits the chamber through a filtered exhaust.
  • Passthrough Ventilation Exhaust Ducts

    Adding a duct flange to the top of the passthrough allows the chamber to be ventilated by a remote blower. The ULPA-filtered inlet, housed in a perforated stainless steel cage, provides the necessary make-up air without contaminating the chamber.
  • Video Camera

    Interior HD video camera records continuously or upon door-opening; can also be used for remote monitoring the transfer chamber.
  • Infrared Load Sensor

    Infrared beams detect objects placed inside the transfer chamber and can be used to trigger an audible alert. The crossed red lines depict the non-visible trigger lines between the IR transmitters and receivers.
  • Automatic Door

    Hands-free operation of the pass-through door, governed by the electronic interlock; automatically closes based on delay timer.
  • Intercom System

    Built-in intercom system lets users easily call and communicate between rooms. No more knocking on windows, shouting, or awkward sign language.
  • LCD Message Panel

    Displays critical environmental information related to the interior chamber such as temperature and relative humidity (customizable).
