Pass-through cabinets, also called pass-through chambers and pass-through windows, allow for the transfer of parts and equipment into and out of a cleanroom.  
These specialized entry systemseduce the need for people to enter your cleanroom, and, thanks to lower traffic within the cleanroom, contamination is significantly reduced.

Clean Air Products’ Pass-Through Chambers

Clean Air Products offers standard and custom pass-thru chambers and other cleanroom equipment to meet your needs. Our pass-thru cabinets feature stainless steel construction—not the particle board that other manufacturers use.

How to Choose the Right Wall Mounted Pass-Thru for Your Application

Pass-through chambers and other cleanroom equipment help prevent contamination and enable manufacturers to comply with industry quality standards. Wall mounted pass-thrus are used by medical and pharmaceutical industries as well as food processing, air and spacecraft, and computers and consumer electronics. Pass-thrus all have similar design standards and features and are manufactured in three levels, including: In addition to your cleanroom equipment requirements, additional considerations in choosing the right pass-through chamber for your application include:
  • How the pass-through chamber will be mounted to the cleanroom
  • Size of wall spaces and any obstructions that will affect door swings
  • Type of material that will be transferred through the cabinet
  • Method of material transfer (by hand, conveyor belt, etc.)
  • How the pass-thru will be used by personnel
  • Any specialized requirements including HEPA filters, fire-rated doors, or pneumatic sliding doors

Our stainless steel pass-thru chambers are constructed with a welded stainless steel shell and unique double-wall construction that encloses and protects the mechanical interlock. This double wall also creates a lipless, flush floor for easy material transfer and cleaning. These wall-mounted pass-thru cabinets are extremely strong and durable, are easy to clean, and provide superior aesthetics for your cleanroom or pharmacy. Except for the viewing windows, these pass-thru chambers are made entirely of metal.
All of our cleanroom pass-through cabinets feature doors with heavy-duty stainless steel frames, stainless steel continuous hinges, tempered safety glass windows, silicone bulb gaskets, and stainless steel over-center compression latches. Stainless steel door frames add strength and prevent long-term warpage and cracking, a common problem with all-plastic doors.

Our wall mounted pass-thru cabinets are available with mechanical interlocks to prevent both doors from being opened at the same time. This helps prevent cleanroom depressurization and contaminant infiltration.
