  • Pressure gauge measures back pressure at the filter to monitor efficiency and remaining filter life
  • Double-walled 304 or 316 stainless steel construction
  • Air return slots along the bottom of the chamber circulate air back through the HEPA/ULPA filter
  • Speed control knob lets users adjust the blower RPM, increasing the airflow and pressure within the chamber
  • Flush mounting on the "clean" side reduces horizontal surfaces that collect particles
  • High-Efficiency Particulate Air (HEPA) filter removes contaminating particles of 0.3 µm or larger at 99.99% efficiency
  • Ultra-Low Particulate Air (ULPA) Filter: 99.999% efficient at 0.12µm particle diameter
  • Brushless DC fan motor is clean, quiet and energy-efficient
  • Status indicator lights flash when blower is not operating
  • LED light bar indicates when the interlock is engaged
  • Audible chimes alert personnel when a pass-through door is opened
  • Choose between wall-mount and floor-mount models to fit your workflow

Features and Benefits

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.

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.

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.

All Stainless Steel FFU with Removable Filter Replacement Screen

The pass through includes an all-stainless steel filter fan unit with a screen for easy HEPA filter replacement. The screen is held in place by double roller catches, which allow the screen to be easily popped out of the ceiling to access the HEPA filter.

Recirculating HEPA Filtration Diagram

By recirculating the interior air, airborne particles are rapidly removed by successive passes through the HEPA filter. Recirculation also minimizes pressure buildup that can cause leakage into an adjacent positive-pressure cleanroom.

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.

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™ 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.

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.

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.

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.

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.

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.

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

  • 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 connect to a remote alarm located up to 200 feet away from the pass through chamber. The crossed red lines depict the non-visible trigger lines between the IR transmitters and receivers.
  • 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.
  • Available UV & LED lights

    Lights are recessed with a transparent lens for easy cleaning; UV-C module neutrailizes microbes using a timed disinfection cycle.
