Introduction
In modern cleanroom design, pass-through chambers are essential for safe and contamination-free transfer of materials between controlled environments. A 90-degree corner smart cleanroom pass-through is a specialized solution that allows material transfer around corners, providing layout flexibility while maintaining strict cleanliness standards. This design helps minimize foot traffic, reduce contamination risks, and streamline cleanroom workflows.
Key Features & Benefits
90-Degree Corner Configuration
Unlike traditional straight-through pass-throughs, the 90-degree corner design enables L-shaped connections between adjacent cleanroom zones. This is particularly useful in tight layouts or when direct line-of-sight between two areas is not possible.
Smart Electronic Interlock
An advanced electronic interlocking system ensures that only one door opens at a time. This prevents cross-contamination by keeping clean and less-clean environments isolated during material transfer.
Recirculating HEPA Filtration
Integrated HEPA filters continuously purify the air inside the chamber. This ensures that sensitive products such as pharmaceuticals or sterile medical components remain protected during transfer.
CleanMount® Flush-Mount Installation
The CleanMount® system allows pass-throughs to be installed or serviced without shutting down cleanroom operations. This reduces downtime, prevents pressure imbalances, and maintains compliance during maintenance.
Durable Stainless Steel Construction
Manufactured from 316L stainless steel, the unit features seamless welds, flush interiors, and lipless designs. These details eliminate particle traps, making cleaning faster and easier while ensuring compliance with ISO and GMP standards.

Optional Enhancements
Refrigerated Pass-Through: Maintains stable low temperatures for sensitive materials, with double-wall insulation and integrated interlocks.
UV Disinfection + HEPA: Combines recirculating HEPA airflow with UV germicidal lamps to reduce microbial contamination—ideal for aseptic and USP 800 environments.
Custom Layouts (T or X Configurations): Multiple-door pass-throughs can be designed for complex cleanroom facilities where several zones intersect.
Applications
Pharmaceutical Manufacturing: Safe transfer of raw materials and sterile products without breaking cleanroom integrity.
Biotechnology & Research: Protecting delicate samples from particle and microbial contamination.
Compounding Pharmacies (USP 797/800): Specialized for sterile drug preparation with options like refrigeration and UV sterilization.
Healthcare & Hospitals: Used in surgical suites and isolation rooms to maintain strict hygiene standards.
Semiconductors & Electronics: Protecting wafers, chips, and components from airborne contamination during handling.

FAQ – 90° Corner Smart Cleanroom Pass-Through
1. What is a 90-degree cleanroom pass-through?
It is a transfer chamber with doors positioned at right angles, allowing materials to move around corners between clean zones without exposing the environment to contamination.
2. Why use a 90° corner instead of a straight pass-through?
The 90° design is ideal when cleanroom walls meet at corners or when direct door-to-door alignment is not possible, offering greater layout flexibility.
3. How does the electronic interlock system work?
The interlock prevents both doors from opening at the same time. This ensures airflow direction and prevents cross-contamination between rooms.
4. What type of filtration is included?
Most smart pass-throughs feature recirculating HEPA filtration, which continuously cleans the chamber air to protect sensitive products.
5. Can the pass-through be installed without disrupting cleanroom operations?
Yes. CleanMount® flush-mount installation allows servicing or installation without penetrating cleanroom walls or shutting down the environment.
6. What materials are used in construction?
Typically, high-grade 316L stainless steel with seamless welds and flush interiors is used for durability and ease of cleaning.
7. Are there options for refrigerated storage?
Yes. Refrigerated pass-throughs are available to maintain low temperatures for pharmaceuticals, vaccines, or other sensitive products.
8. Can UV disinfection be added?
Yes. Some models combine HEPA airflow with UV germicidal lamps to reduce microbial contamination.
9. In which industries are 90° corner pass-throughs most used?
They are widely used in pharmaceuticals, biotechnology, healthcare, semiconductor manufacturing, and food or cosmetic cleanrooms.
10. What compliance standards do these systems meet?
They are designed to support ISO 14644, GMP, and USP 797/800 cleanroom requirements.
Conclusion
The 90-degree corner smart cleanroom pass-through is a powerful solution for facilities requiring flexible layouts and strict contamination control. With advanced interlocking, HEPA filtration, and options like refrigeration and UV sterilization, it enables safe, efficient, and compliant transfer of materials across cleanroom zones.
