Airkey, a pioneering Chinese manufacturer of precision cleanroom solutions, has announced the successful production and delivery of over 70 specialized pass boxes (also known as pass through) to customers in Kenya and Paraguay. This significant milestone underscores the company’s commitment to providing advanced, customizable contamination control solutions for the global market, particularly in regions with growing pharmaceutical, biotechnology and electronics manufacturing sectors.
Project highlights: Tailored solutions for diverse global needs
The recent batch of shipments includes both static and dynamic pass boxes, designed to meet the stringent requirements of modern cleanroom operations. These units serve as critical barriers, ensuring materials can be transferred between different zones without compromising the integrity of the controlled environment.
Product portfolio: Static vs dynamic pass boxes
-
Static pass boxes: The cost-effective workhorse
Application: Ideal for transfers between cleanrooms of the same classification (e.g., ISO 7 to ISO 7).
Design principle: A sealed, interlocked chamber that prevents simultaneous door opening, eliminating cross-contamination risks.
Advantages: Simple, reliable and energy-efficient, offering a budget-friendly solution for standard material transfer needs. -
Dynamic pass boxes: Advanced decontamination performance
Application: Essential for transferring materials from lower-classification areas into higher-classification cleanrooms (e.g., from ISO 8 to ISO 5).
Design principle: Equipped with integrated HEPA/ULPA filters and laminar airflow systems that actively cleanse the chamber and objects within.
Advantages: Provides a certified clean environment inside the chamber, ensuring objects are fully decontaminated before entry into critical zones.
Core safety features
Both types are equipped with advanced mechanical or electronic interlocking systems that guarantee only one door can be opened at any time. This fail-safe mechanism is fundamental to maintaining pressure differentials and preventing airborne contamination. Both static and dynamic pass boxes incorporate radiused internal corners—a critical design feature that eliminates sharp 90° angles where contaminants could accumulate. This seamless construction ensures complete cleanability while preventing particulate entrapment, aligning with stringent cleanroom hygiene protocols.
Airkey customization capabilities: Engineering without limits
Understanding that no two cleanrooms are identical, Airkey specializes in engineered-to-order pass box solutions:
-
Custom dimensions: Designed to fit precise spatial constraints and handle oversized equipment or batch materials.
-
Multi-door configurations: Unique 3-door pass boxes for complex workflow layouts involving multiple rooms or zones.
-
Specialized designs: Floor-mounted pass boxes allowing seamless trolley and cart transfer without manual lifting.
-
Material & finish options: Available in stainless steel (304/316L), powder-coated steel or specialized cleanroom-compatible materials, with finishes tailored to industry requirements.
-
Integration features: Can be pre-equipped with UV-C germicidal lamps, VHP (Vaporized Hydrogen Peroxide) ports, etc.
Technical specifications & compliance
All Airkey pass boxes are designed and validated to meet international standards:
-
ISO 14644-1 for cleanroom classifications
-
GMP guidelines for pharmaceutical and biotechnology applications
-
IEST-RP-CC002 for pass box design and testing recommendations
-

Applications across industries
Airkey pass boxes are deployed in:
-
Pharmaceuticals: Transfer of raw materials, intermediates and tools into Grade A/B/C zones.
-
Medical devices: Movement of components between packaging and assembly cleanrooms.
-
Electronics: Protecting sensitive semiconductors and PCBs from particulate contamination during transit.
-
Food & nutraceuticals: Maintaining hygiene protocols in supplement and high-purity food production.
