• Static Pass Box

Static Pass Box is specifically designed that aids in the material transfer without much personnel movement.Furthermore,the Static Pass Box also acts as a hindrance for entrance of contaminants in clean room and other classified areas.

• Dynamic Pass Box

A Dynamic Pass Box is an interlocked, HEPA-filtered air shower chamber installed in a wall between two areas of different cleanliness classes. Its primary function is to decontaminate materials by blowing HEPA-filtered air over them before they enter the higher-cleanliness zone.

Features at a Glance

• High-Efficiency Contamination Barrier

1. Built-in FFU and HEPA/ULPA high-efficiency filter, continuously generating unidirectional laminar flow at a speed of 0.3~0.5m/s to form a positive-pressure clean zone inside the cavity, preventing the infiltration of external non-clean air.

2. The airflow can wash away dust and microorganisms attached to the surface of materials, with a purification efficiency of ≥99.97% for 0.3μm particles, avoiding contaminants entering high-cleanliness areas along with materials.

3. It does not rely on external clean air supply, and the laminar flow forms an independent closed loop, ensuring that the barrier effect is not affected by pressure difference fluctuations in the cleanroom.

• Stronger Compliance

1. The cleanliness level inside the cavity can reach ISO Class 5, fully meeting the material transfer requirements of high-grade clean areas specified in standards such as GMP and ISO 14644.

2. Equipped with double-door electronic interlock and laminar flow operation status monitoring function, it can record data including material transfer time and filter operation duration, facilitating audit trails.

3. Some models are integrated with UV sterilization linkage function, providing dual protection of laminar flow purification and UV disinfection, suitable for harsh scenarios such as biomedicine and sterile preparation production.

• Convenient and Efficient Operation

1. The fan runs continuously, eliminating the need for preheating before startup; it is ready for use immediately, shortening the waiting time for material transfer.

2. The cavity is designed with no dead corners, and the stainless steel inner wall enables easy cleaning and disinfection, reducing the man-hours required for cleaning and maintenance.

3. Modular structure allows installation without damaging the cleanroom wall structure, making it suitable for both new construction and renovation projects.

• Energy-Saving, Stable and Durable

1. Adopts a variable-frequency fan design that automatically adjusts air velocity according to cavity pressure difference, reducing energy consumption by more than 30% compared with the traditional static pass box with external clean air supply.

2. Real-time monitoring of filter resistance triggers an audible and visual alarm when the resistance exceeds the standard, preventing purification failure caused by filter clogging.

3. The door body is made of tempered glass and sealing rubber strips, featuring wear resistance and corrosion resistance, with a service life of 8~10 years.

Products Description

• Observation window: The observation window is the key feature that transforms a pass-through from a "black-box" device into an interactive, monitorable, and trustworthy intelligent control node.
• Interlock system: The cleanroom interlock system is the most direct embodiment of the Quality by Design (QbD) concept at the facility level. Through "hard-wired" engineering controls, it establishes an underlying line of defense for product quality and patient safety that activates automatically without requiring human intervention.
• Differential pressure gauge&Detection port: The value of the differential pressure gauge lies in providing continuous status awareness and immediate alerts, serving as the eyes of daily operations.
• ARC Corner: ARC Corner represents a fundamental shift in cleanroom design—from passively tolerating contamination to proactively eliminating contamination risks.
• Corrosion-resistant stainless steel: Corrosion-resistant stainless steel is the material of choice for high-standard cleanroom construction, with its advantages profoundly impacting the cleanroom's performance, lifespan, and compliance.
