  FEATURES & BENEFITS | Cleanseam+ Pass-Through
Alt Text
Flush-Mount Designs
Seamless mounting bracket fits flush against the cleanroom wall to eliminate surfaces where particles collect.
Beveled Exit Slots
Removable Doors
Lift-off doors can be removed for easy cleaning or replacement.
Isolated Interlock
Interlock hardware is isolated to keep the transfer chamber smooth and easy to clean.

Smooth, Lipless Chamber
Radius corners and seamless design simplifies cleaning; no-lip entry eliminates clearance obstructions.

All Stainless Steel LiftLatch
Durable stainless steel door latch won't corrode or slough particles, common problems with plated hardware.
New hinge design
Floor-Mount Ramp
Angled slopes on stainless steel ramps allow easy transport of carts in and out of the chamber.


Flush-Mount System Allows Servicing or Replacement without Cleanroom Shutdown!

passthrough replacement steps
Unique quick-mount system installs in under five minutes, regardless of wall thickness and without contamination
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)

The simplicity of the flush-mount 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.

This CleanSeam+ Pass-Through isolates the interlock in a double-wall housing, providing the optimal transfer chamber for the broadest range of critical applications, including cleanliness requirements to ISO 4 and bio/pharmaceutical operations that require frequent cleaning and sterilization.

Unique Flush-Mount Installation for Cleaner, Faster Mounting

Every design feature, from its installation system to latch construction, reinforces clean performance and a long service life. The unique integral wall bracket mounts the chamber flush against the cleanroom wall without the need to drill holes in the wall. With no horizontal surfaces to collect dust, the chamber exterior helps maintain the most critical cleanroom requirements.

Internal and External Surfaces Optimized for Cleaning and Sterilization

The CleanSeam+ Pass-Through uses coved corners (instead of welded seams) and hence has no cracks, grind marks, burrs or other imperfections that can harbor germs and other contaminants or snag wipers. The lipless front and rear edges impose no clearance restrictions, simplifying parts transfer.

All construction materials support clean operations. The all-electropolished 304/316 SS chamber surfaces and hardware stand up to common cleaning agents and won’t chip or flake. The chamber’s ergonomic all-stainless steel LiftLatches eliminate rotary motion that strains wrists and chamber hinges. Because they are externally mounted, they won’t cause metal-on-metal scraping and contamination, as rotary latches do. The one-piece, heat-formed gaskets are mechanically fused to the stainless-steel door reinforcements. They don’t use adhesives, so they won’t creep, deform or outgas—unlike weather-strip-style gaskets.

Pass-Through doors feature lift-off hinges for easy removal and disinfection.  All windows are made of static-dissipative PVC.

Terra customizes to meet special requirements for pass-through sizes,
materials and configurations. Call to discuss your application.

Why is Electropolishing Critical?
Removes iron and other surface impurities that cause corrosion
Draws chromium and nickel to form a hard, protective finish
Removes irregularities (pits and burs) for an ultra-smooth surface that's easy to clean
More on Terra's electropolishing procedures...
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.
