Laminar flow transfer box: a "safety guardian" in clean environments.
In environments with stringent cleanliness requirements, such as biopharmaceuticals, semiconductor manufacturing, and scientific research, laminar flow transfer cases are core equipment for ensuring safe material transfer. Through precise airflow control and a high-efficiency filtration system, they create a "sterile barrier" between clean and non-clean areas, effectively preventing cross-contamination.
Core Principle: Laminar Flow Purification Technology
The laminar flow transfer case is equipped with a high-efficiency particulate air filter (HEPA/ULPA) and a centrifugal fan, forming a unidirectional vertical laminar flow. When items are placed in the case, clean airflow evenly covers their surface from the top, "washing" dust, microorganisms, and other contaminants to the bottom exhaust vent, ensuring that items remain in a sterile environment throughout the transfer process. Some high-end models also integrate ultraviolet germicidal lamps to further kill residual microorganisms.
Safety Design: Multiple Protection Mechanisms
Double Door Interlock: Two doors are linked through mechanical or electronic structures; when one door is open, the other automatically locks to prevent air convection contamination.
Differential Pressure Control: Maintains positive pressure inside the case (typically 10-15 Pa) to prevent the intrusion of unfiltered external air.
Intelligent Monitoring: Real-time display of parameters such as differential pressure, air velocity, and filtration differential pressure; automatic alarm in case of abnormalities to ensure stable operation.
Application Scenarios: Precisely adapted to industry needs
Biopharmaceuticals: Transferring raw materials and equipment in aseptic preparation production to prevent microbial contamination;
Semiconductor Manufacturing: Transferring precision components such as wafers and photomasks to prevent particle adhesion affecting yield;
Scientific Research: Transferring samples in biosafety laboratories to block the spread of high-risk pathogens;
Food Processing: Transferring materials between clean and general areas to ensure food safety.
Advantages Summary: High efficiency, safety, and flexibility. The laminar flow transfer box features a modular design to meet different size requirements and supports customized expansion (such as adding electrostatic elimination and temperature control modules). Its simple operation, low maintenance cost, and compliance with international standards such as GMP and FDA make it an indispensable "safety hub" in clean production. Whether ensuring drug quality, improving chip yield, or safeguarding scientific research safety, the laminar flow transfer box consistently provides reliable protection for high-cleanliness environments with its precise purification capabilities.
