Product Description
The Air Shower Pass Box is a critical contamination control device designed for material transfer between cleanrooms of different cleanliness levels. It uses high-velocity turbulent airflow to remove surface particles from items before they enter high-grade clean areas. Unlike a standard Cleanroom Transfer Window, this equipment actively cleans the items being transferred, significantly reducing the risk of cross-contamination. The built-in Electronic Interlock Pass Box system ensures that both doors cannot be opened simultaneously, maintaining the pressure differential and cleanliness integrity of your controlled environment. This makes the Air Shower Pass Box an indispensable tool for pharmaceutical manufacturing, biological research, semiconductor fabrication, and food processing facilities where strict hygiene standards must be maintained.

Product Features
The Air Shower Pass Box delivers superior contamination control through its unique design and robust construction.
1. High-Speed Turbulent Flow Cleaning
Equipped with 4-6 multi-angle adjustable nozzles, this unit generates high-velocity turbulent airflow (22-28 m/s) that effectively removes surface particles from materials. The HEPA filter ensures 99.99% efficiency at 0.3μm particle size, providing ISO Class 5 for your critical processes.
2. Reliable Electronic Interlock System
This Electronic Interlock Pass Box feature prevents both doors from being opened simultaneously. This maintains the pressure differential between rooms and prevents unfiltered air from entering the clean area. An audible alarm alerts operators if the interlock is tampered with.
3. Durable Stainless Steel Construction
Constructed entirely from SUS304 stainless steel, this Cleanroom Transfer Window offers excellent corrosion resistance and is easy to sanitize. The seamless interior design eliminates the dead corners where contaminants could accumulate, making it ideal for GMP-compliant facilities.
4. Energy-Efficient Operation
The built-in infrared sensor activates the air shower only when items are placed inside and the door is closed. This smart control system reduces energy consumption by up to 60% compared to manually operated units.

Product Applications
The Air Shower Pass Box serves critical functions across multiple industries where contamination control is paramount.
- Pharmaceutical Manufacturing
In GMP-certified pharmaceutical facilities, this equipment transfers raw materials, samples, and small equipment between different cleanliness zones. The HEPA-filtered turbulent flow ensures that no viable particles enter the aseptic processing area, protecting both product quality and patient safety.
- Biotechnology and Laboratory Research
For biosafety laboratories, the Electronic Interlock Pass Box maintains containment integrity while allowing safe transfer of samples and supplies. The interlock system prevents accidental breaches that could compromise experimental results or release hazardous materials.
- Electronics and Semiconductor Production
Semiconductor fabrication requires ISO Class 5 or cleaner environments. This Cleanroom Transfer Window allows wafer cassettes, masks, and other sensitive components to enter clean areas without introducing particle contamination that could cause microchip defects.
- Food and Beverage Processing
Food safety regulations demand strict hygiene control. The stainless steel construction and turbulent flow cleaning make this device ideal for transferring ingredients and packaging materials into high-hygiene processing zones.
