Product Details
  • ISO Rating: ISO 6, ISO 7, ISO 8
  • Fully welded cleanroom pass-through without crevices, ideal for medical/pharmaceutical applications
  • Continuous welds are suitable for moderate sterilization protocols
  • Automatic door interlock allows only one door to open at a time to prevent cross-contamination
  • Doors are leak-rated by UL for tight seal to maintain cleanroom air pressure gradients
  • Stainless steel framed doors, latches, and hinges extend service life of pass-through chamber
  • Cleanroom pass throughs reduce foot traffic, improve cleanliness, safety, productivity, and much more.
  • Chamber Design:
  • Corrosion resistant all-304 stainless steel surfaces resists most harsh chemicals and alcohol-based cleaning agents, won’t produce contaminants during sterilization.
  • Seamless welds eliminate hard-to-clean cracks and crevices where contaminants can collect.
  • Floor-mounted design includes removable ramps to support transfer of carts and heavy equipment between controlled spaces.
  • Door Design:
  • Access doors with 304 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.
  • Heavy-duty stainless steel lift latches included to minimize scratching, corrosion and contamination resulting over time that can occur with chrome-plated latches.
  • Chemical-resistant, static-dissipative PVC windows prevent static-clinging of particulates.
  • Order replacement door(s) to avoid critical operation delays should a door be damaged and require immediate replacement.
  • Includes:
  • (1) Automatic mechanical interlock
  • Mounting brackets; Standard bracket mounting is 2" (51mm) from the front on the cleanroom side - specify other desired location

CleanSeam 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.

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.

Continuous-Seam Welds Eliminate Particle Traps!

CleanSeam™ Pass-Throughs feature fully welded, seamless interiors, to eliminate hard-to-clean cracks and crevices that can harbor contaminants. The continuous-seam welds are ground smooth to simplify cleaning and sterilization.

Pass-Through Chamber Interlock

Terra’s automatic mechanical interlock prevents cross-contamination by allowing one door to be open at a time. Encased in stainless steel, the mechanism is rated for millions of operations, more than enough to last the lifetime of the pass-through.

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.

Stainless Steel Reinforced Doors and Handles

Doors on professional-grade pass-through chambers are reinforced with stainless steel frames, which lend rigidity, improve the seal, and extend the service life of the doors.

One Piece Elastomer Gasket

The white, “e”-shaped gasket provides a flexible seal that will not creep or deform over time. The gasket is made of a non-outgassing, thermoplastic elastomer that is resistant to harsh chemicals and extreme temperatures.

  • 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.
  • 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.
  • CleanTop™

    The CleanTop™ is designed for installations that require the chamber to be centered in the wall. The 30° sloping top on the cleanroom-side minimizes particle accumulation and accommodates laminar downward airflow.
  • Replacement Pass-Through Doors to Avoid Costly Down-Time

    Avoid costly disruptions and down time - keep a replacement door on hand! Doors attach in minutes and can prevent a costly shut-down if the original is damaged. To order, add "-LH" (left-side hinge) or "-RH" (right-side hinge) to the pass-through part number.
  • Grounding Terminals

    Grounding terminals are ideal for the most static-sensitive applications (must be ordered with chamber; cannot be retrofitted).
  • Mounting System for Tempered Glass Wall Panels

    This unique mounting system allows installation of pass-through chambers on Terra Universal's modular cleanrooms with tempered glass wall panels.
  • Support Brackets for Pass-Through Chambers

    Stainless steel support brackets are recommended for pass-throughs deeper than 24". Brackets fasten to the wall and the body of the chamber rests upon the horizontal bar; no fasteners are used on the pass-through itself.
  • Passthrough Chamber Door Stop

    This stainless steel door stop limits the arc of the pass-through door's swing to 90°, preventing damage to wall, door latch and other components. Door stops can be adjusted to allow other angles.
