Product Details

• Self-closing, fire-rated door bears the UL 10B label for 90-minute fire exposure (suitable for 2-hour wall rating)

• 2"-thick insulation lines the inside of the fire-rated door and includes a heavy-duty, paddle-style pull-latch

• Includes wire-free, fire-rated glass-ceramic window that is also impact-resistant

• Opposite-side pass-through door is made of static-dissipative PVC, reinforced by stainless steel, and uses a one-piece, thermoplastic gasket to provide a flexible seal

• Smooth internal surfaces, with rounded corners and lip-less chamber, make these pass-throughs ideal for bio/pharmaceutical cleanroom operations

• 316-stainless steel fabrication provides durability, smooth surfaces, and high corrosion-resistance

• Double-wall construction allows automatic mechanical interlock to be isolated outside the transfer chamber for optimal cleanliness and long operating life

• Door interlock system prevents opposite door from opening while accessing the pass-through, preventing sudden influxes of unclassified contaminants

• To maintain UL fire-rating certification, maximum fire-rated door dimensions not to exceed 30”W x 45”H

CleanMount Basics

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

Fire-Rated CleanMount® Pass-Through Chamber

Fire-rated pass-throughs protect personnel, equipment, and facility by maintaining the integrity of the fire-rated wall. They bear the UL 10B label for 90-minute fire exposure.

Concealed Automatic Interlock Simplifies Cleaning

Automatic door interlock is hidden and isolated from the main chamber. This provides an unobstructed, smooth, and seamless interior for easy wipe down and sterilization. Ideal for critical bio/pharmaceutical processing.

Fire-Rated Pass-Through Glass Window

The wire-free glass-ceramic incorporate a surface-applied, fire-rated film and is impact rated for additional safety. These windows feature a high level of clarity and offer protection from either side.

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

Stainless steel-reinforced CleanMount® doors provide superior strength and durability. Heavy-duty barrel hinges allow the doors to lift off for easy replacement or more thorough cleaning/decontamination.

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.

Spring-Loaded Fire-Rated Passthrough Hinge

Spring-loaded hinges provide the self-closing capability required in a fire-rated wall. Automatic closing doors also simplify operation for operators with hands full.

Insulated Fire-Rated Pass-Through Door

Terra’s fire-rated door meets UL 10B requirements for 90-minute fire exposure, including hose-stream testing. The inside of the door is lined with 2”-thick SuperWool® Plus insulation to reduce heat transfer from elevated room temperatures.

  • LED Recessed Light
    Activates when either pass-through door opens; flush with the wall surface, covered by a static-dissipative PVC lens.
  • 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; can be used to trigger an audible alert.
  • Iris Scanner
    Fully automated iris scanner for secure, hands-free access (includes datalogging and optional secondary keycard reader).
  • Removable Pass-Through Sliding Shelves
    Removable stainless steel sliding shelves with runners simplify cleaning, increase storage surface area of chamber space, and allow easy access to every inch of shelf space.
  • Automatic Door
    Hands-free operation of the pass-through door, governed by the electronic interlock; automatically closes based on delay timer.
  • LCD Message Panel
    Displays critical environmental information related to the interior chamber such as temperature and relative humidity (customizable).
  • 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.
  • Interlock Status Lights
    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.
  • Wireless Door Alert
    Alarm bell rings when its assigned door is open (two bells per chamber); plugs into a standard wall outlet.
