Efficient material transfer is essential for maintaining cleanroom integrity in pharmaceutical manufacturing, biotechnology laboratories, hospitals, electronics production, and food processing facilities. Frequent opening of cleanroom doors can disturb airflow, increase airborne particle levels, and introduce contaminants into controlled environments.
A Clean Pass Box provides a safe and efficient solution for transferring small materials between cleanrooms or between clean and non-clean areas while minimizing the need for personnel movement. By combining interlocking doors, UV sterilization, and high-sealing construction, the equipment helps maintain cleanroom cleanliness and significantly reduces the risk of cross-contamination.
Designed for reliable daily operation, the Clean Pass Box has become an indispensable component of modern cleanroom contamination control systems.
A Clean Pass Box is a cleanroom transfer device designed to safely move tools, samples, documents, and other small materials between different controlled areas without compromising environmental cleanliness.
Instead of opening cleanroom doors repeatedly, operators transfer materials through the pass box, maintaining pressure balance and reducing airborne contamination.
The equipment is widely used wherever contamination control is critical, including pharmaceutical production, hospitals, biological laboratories, electronics manufacturing, and food processing facilities.
The Clean Pass Box isolates two adjacent rooms through a double-door interlocking system. During operation, only one door can be opened at a time, effectively preventing direct airflow exchange between different areas.
Before materials are transferred, the built-in UV sterilization system can be activated to disinfect item surfaces, reducing microbial contamination risks.
The high-sealing cabinet structure further minimizes air leakage, ensuring that pressure differentials between clean and non-clean areas remain stable throughout the transfer process.
This combination of physical isolation and surface sterilization provides an efficient and reliable contamination control solution.
The electronic interlocking mechanism ensures that the two doors cannot be opened simultaneously.
Benefits include:
• Prevention of cross-contamination
• Stable cleanroom pressure
• Improved transfer safety
• Standardized operating procedures
This design effectively separates clean and non-clean environments during material transfer.
The built-in UV sterilizer provides surface disinfection before materials enter the clean area.
Advantages include:
• Reduced microbial contamination
• Independent UV control
• Easy operation
• Improved material cleanliness
The UV lamp can be switched on and off independently according to operational requirements.
The cabinet adopts an inner and outer housing design with rounded internal corners.
Key benefits include:
• Smooth, gap-free construction
• Excellent sealing performance
• Easy cleaning and maintenance
• Reduced contamination accumulation
The rounded interior eliminates dead corners where dust or microorganisms could collect.
The double-layer tempered glass doors provide excellent visibility during material transfer while maintaining structural strength.
Combined with stainless steel handles, the design offers:
• Safe operation
• Long service life
• Easy observation
• Attractive appearance
A centralized control panel simplifies equipment operation and allows users to control UV sterilization and other functions conveniently.
Optional paging intercom systems improve communication between operators on both sides of the pass box, enhancing workflow efficiency.
The Clean Pass Box is suitable for a wide range of contamination-controlled environments.
