Pass-through cabinets, also called pass-through chambers, pass through boxes, and pass-through windows allow for the transfer of parts and equipment into and out of a cleanroom.
These specialized entry systems reduce the need for people to enter your cleanroom, and, thanks to lower traffic within the cleanroom, contamination is significantly reduced.
Clean Air Products offers standard and custom pass-thrus as well as a variety of other cleanroom equipment to meet your needs. Our pass-thru cabinets feature stainless steel construction—not the particle board or plastics that other manufacturers use.

Choosing the Right Pass-Thru Door for Your Application
Pass-through boxes 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:
Fully welded body design for aseptic manufacturing, compound pharmacies and chemo drug pharmacies
Bio-design wall mounted pass-thrus for terminal sterilization processing, nanotechnology and production facilities with strict isolation procedures
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
Stainless Steel Pass Thru Windows
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.

Available Pass-Thru Chamber Configurations
Pass throughs help to eliminate the volume of unnecessary traffic through the cleanroom, reducing cross-contamination and maintaining the positive pressure of the cleanroom. Floor mount cleanroom pass throughs allow carts and larger items to enter the cleanroom, while wall mount models expedite transfer of materials through an opening installed in the cleanroom wall at a secure and accessible standing height.
Wall Mounted 90° Pass-Thrus
Wall mounted 90° pass-throughs are designed for cleanrooms where space limits require a 90 Degree turn in the PassThru. Wall mounted 90° pass-throughs feature a double wall design, stainless steel integrity, and are easy to clean.
Fire Rated Pass Through Windows & Doors
Fire rated pass thru windows and door systems provide an enclosed airlock space between a cleanroom and an adjoining area that prevents particles from entering the clean room. Fire rated pass thru cabinets are easy to operate and provide cleanroom levels of protection with additional fire safeguard advantages. Before choosing a fire rated cleanroom pass through system, you will need to consider the type and size of materials you will be transferring, and which level of pass-through your industry standards require.
Multi-Stack Pass Thrus
Multi-stack pass throughs provide multiple windows that are efficiently stacked for convenient access when more than one pass through is required.
Lead-Lined Wall Mounted Pass-Thrus
