  • Economical chambers enhance operational cleanliness by eliminating the need for garbed personnel to transfer parts into and out of the lab or cleanroom

  • Transparent windows allow full visibility of chamber interior
  • Fire-rated stainless steel door (UL-B for 90-minute exposure) available
Terra's ValuLine Pass-Throughs provide durable, non-contaminating transfer chambers at low cost.

Choose from three materials: chemical-resistant polypropylene includes static-dissipative PVC (SDPVC) viewing windows for compatibility with most cleaning agents, including alcohol; black acrylic includes clear acrylic windows; durable 304 stainless steel resists damage from chemicals and has doors made of static-disspative PVC with viewing window, or solid fire-rated stainless steel. All plastic models feature a stainless steel protective shield on the chamber floor to resist scratches and prolong chamber service life.

Dual expansion latches provide firm door closure. Unlike rotary latches, which often generate particles inside the chamber as the latch scrapes the internal chamber surface, these latches are physically isolated from the transfer area for optimal cleanliness.

System Options

The optional FirmLok™ Interlock eliminates the chance of cross-contamination by ensuring that only one pass-through door at a time can open. This no-maintenance, reliable mechanism, rated for millions of operations, automatically engages the moment a door opens. It is made of all-stainless steel components and is located within the internal chamber wall between the opposing door latches.

The fire-rated door is UL-B rated for 90-minute fire exposure, suitable for two-hour wall rating (maximum temperature rise to 250°F in 30 minutes); access door on non-rated side has an SDPVC viewing window. Self-closing, self-latching steel doors are 2.56"-thick, non-insulated, with a pull handle and concealed hinge. Doors are 16-gauge and feature flush mounting frames with reinforced edges.

More pass-through accessories…

ValuLine Pass-Through Chambers require a wall cut-out 0.5" [13 mm] larger than the chamber width and height. All units come with mounting brackets and hardware that frame the chamber and ensure secure mounting.

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.
