Shutting the Door on Contamination

These Pass-Through Chambers cut down significantly on traffic and contamination by providing a better, safer way to transfer equipment and paperwork.

304 Stainless steel or powder-coated steel pass-throughs ensure clean operation. For especially stringent particle requirements, select an UltraClean™ electropolished 304 stainless steel pass-through.

Polypropylene and PVC models are suitable for chemical pass-through applications, and Static-Dissipative PVC models combine excellent chemical resistance with a surface resistivity of about 107 ohms/square for enhanced static and particle control. Each model features viewing windows of a compatible material.

Doors on either side can be outfitted with a mechanical interlock that keeps personnel from passing particles through the chamber. This device allows only one door at a time to open, and thus the amount of air that can enter the cleanroom is restricted to a very small volume. The no-maintenance interlock has no power, gas, or other facility requirement, so it continues to operate when other systems shut down.


ULPA Filtered Air Shower Clears the Air!

Terra offers an ULPA filtered air shower for enhanced particle control.

This option incorporates a brushless motor and 125 CFM (212.5 m³/hr) variable-speed impeller to draw air from the "clean" side of the pass-through into an ULPA filter (rated 99.999% efficient with 0.12µm-diameter particles).

A magnetic sensor switch, installed on the "dirty" side door, activates the unit after the door has been opened and then closed. The shower washes the chamber with ULPA-filtered air to remove any contaminants that might have entered the chamber (the operation period is adjustable from 15 to 180 seconds). During operation, a red status light in the "cleanroom" side of the shower glows to warn operators not to open a door. When the shower shuts off, a green status light indicates that the door may be opened.

Exhaust air flows out of vents on the "dirty" side of the pass-through chamber (a microporous filter eliminates the chance of contamination in the event of a negative pressure). The cleanroom intake ensures a long filter life, and filter change-outs can be performed in a matter of seconds.


Pass-Through Installation

Cleanroom Pass-Through Installation

Cleanroom Pass-Through Chambers can be installed in a number of ways, depending on the wall or door that will support them. The ordering chart indicates the cut-out size necessary to support each model size (simply add .5" [13 mm] to the chamber width and height). Terra offers mounting brackets and hardware to ensure secure mounting. In most cases, a bracket kit provides ample support. Models are available for either wall mounting (at a convenient standing height) or floor mounting (to allow passage of carts and other equipment along the floor). Select support brackets for 36"D (914 mm) wall-mount models. Note: Brackets are mounted to allow chambers to protrude 2" (51 mm) on the cleanroom side (specify other desired position).

Cleanroom Pass-Through Ordering Guide

Consider the following options in making your selection:

Wall or Floor Mount? Wall-mount models can be positioned at a comfortable standing height; floor-mount models include a low-profile ramp to allow carts to be wheeled into the chamber. Special mounting hardware is included for each model. Order support brackets for larger wall-mount models (see illustration above). Your wall cutout should be .5" (13 mm) larger than the overall height and width of your chamber.

Pass-Through Chamber Material? Select among seven standard materials. Others (including polycarbonate and dissipative polycarbonate) are also available.

Sliding Doors? These easy-open doors eliminate clearance requirements.

Interlocks? Interlocks are recommended to prevent cross contamination.

Reinforced Doors—Plastic cabinets come with stainless steel reinforced door frames on a standard basis.

Other Pass-Through Options include a filter/blower module, shelves (with electropolished stainless steel racks), illuminator, and grounding terminals.


Standard Pass-Through Mounting

All models include mounting brackets (stainless or powder-coated steel). All brackets require .25" (6 mm) clearance between the wall cut-out and the pass-through. Standard mounting is 2" (51 mm) from the front of the cleanroom side (specify other desired location). For electropolishing, add "-2" to the part number and $75 to the price.
