Move materials between controlled spaces while helping protect the integrity of your cleanroom.
Atmos-Tech designs and manufactures cleanroom pass-through chambers for material transfer between cleanrooms, controlled environments and adjacent spaces. Standard and custom configurations are available with multiple construction materials, interlock systems, filtration options, door configurations and accessories.
Whether you need a standard stainless steel pass-through or a custom system engineered around your facility, Atmos-Tech can help configure the chamber around your application.
Cleanroom Pass-Through Chambers for Controlled Material Transfer
Opening a cleanroom door every time a tool, component or material needs to enter or leave the space creates unnecessary personnel movement and can complicate contamination-control procedures.
A through-wall pass-through provides a dedicated transfer point between spaces.
Atmos-Tech pass-through systems use an interlocking door arrangement that allows only one door to open at a time, helping maintain cleanroom pressure and reduce particle migration between adjoining areas.
Pass-through chambers can be used for transferring:
- Production materials
- Components
- Tools
- Supplies
- Packaged product
- Samples
- Cleaning materials
- Equipment and parts
Standard and Custom Cleanroom Pass-Throughs
Every facility has different wall systems, space constraints and material-flow requirements.
Atmos-Tech offers standard sizes as well as custom pass-through dimensions and configurations.
Custom configurations may be appropriate when:
- Existing wall openings dictate chamber dimensions
- Larger equipment or materials must pass through
- Multiple-door configurations are required
- Automatic doors are desired
- Facility layouts require non-standard dimensions
- A specific material or finish is required
- HEPA or ULPA filtration is needed

Stainless Steel Cleanroom Pass-Through Chambers
Stainless steel is a common choice for pass-through chambers in cleanroom and critical manufacturing applications because it provides a smooth, durable surface suitable for regular cleaning.
Atmos-Tech offers stainless steel and electropolished stainless steel configurations as well as other construction options depending on the application. Current catalog options also include epoxy-painted steel, polypropylene and laminated particleboard configurations.
Material selection should be based on:
- Cleaning procedures
- Chemical exposure
- Process requirements
- Facility standards
- Cleanroom classification
- Durability requirements
- Budget
Mechanical and Electrical Interlocking Pass-Throughs
Maintaining separation between adjoining spaces is one of the primary functions of a cleanroom pass-through.
Atmos-Tech offers both mechanical and electrical interlock systems designed so that only one pass-through door can be opened at a time.
This helps minimize direct exposure between the two rooms while materials are transferred.
Mechanical Interlocks
Mechanical systems can provide a straightforward interlocking arrangement without the same electrical requirements as electronically controlled systems.
Electrical Interlocks
Electrical interlocks may be appropriate for applications requiring additional controls or integration with a more sophisticated transfer process.
The best configuration depends on the facility and operating requirements.
HEPA & ULPA Filtered Pass-Through Chambers
Some material-transfer applications require the interior of the pass-through itself to maintain a highly controlled environment.
Atmos-Tech offers optional laminar-flow HEPA/ULPA filtration for its pass-through systems. Its catalog describes filtered configurations capable of maintaining environments up to ISO Class 4 inside the chamber when appropriately configured.
Filtered pass-through systems may be considered for sensitive applications where materials must remain protected during transfer.

Pass-Through Chambers for Semiconductor & Advanced Manufacturing
Semiconductor, electronics and other advanced manufacturing environments can also benefit from dedicated material-transfer systems.
A properly specified pass-through can help support the facility’s overall contamination-control strategy while improving movement of parts and materials between production spaces.
Custom chamber sizes can also accommodate specialized components, carriers or process equipment.
How to Specify a Cleanroom Pass-Through
Before requesting a quote, consider the following:
Chamber Dimensions
What is the largest item that must pass through the chamber?
Wall Opening
Is the pass-through being installed into a new wall or an existing opening?
Wall Thickness
Provide the wall construction and approximate thickness.
Chamber Material
Determine whether stainless steel or another construction is required.
Door Configuration
Consider swing doors, automatic doors or vertical sliding doors.
Interlock
Identify whether mechanical or electrical interlocking is preferred.
Filtration
Determine whether the chamber requires HEPA/ULPA-filtered airflow.
Lighting
Determine whether interior lighting or UV lighting is required.
Fire Rating
Identify any architectural or code-driven fire-rating requirements.
Providing this information early can make the quoting and configuration process much more efficient.
