What are the advantages of laminar flow pass box self-cleaning?
What are the advantages of laminar flow pass box self-cleaning?The self-cleaning function of the laminar flow transfer window provides multi-dimensional advantages for a clean environment through technological innovation and system design, the specific advantages are as follows:1. Consistently maintain high cleanliness Dynamic purification: Through laminar circulation (wind speed 0.38-0.57m/s) and efficient filtration (H14 level), the internal air is filtered in real-time to ensure that the cleanliness above 100 level (ISO 5 level) is always maintained in the transfer window to avoid the accumulation of pollutants. Unidirectional airflow protection: the laminar flow mode of up and down eliminates air flow dead corners and prevents cross-contamination, which is especially suitable for environmentally sensitive industries such as biopharmaceuticals. 2. Dual sterilization of surface and space Ultraviolet synergy: The built-in ultraviolet lamp (254nm) irradiates for ≥15 minutes to sterilize the surface of articles, while laminar flow reduces the survival rate of microorganisms, forming an "airflow barrier + ultraviolet" double protection. VHP sterilization expansion: Some models support vaporized hydrogen peroxide (VHP) sterilization, suitable for sterile drugs, medical devices, and other high-risk scenarios. 3. Prevent the spread of pollution Pressure dynamic balance: Through the pressure control of the inner cavity (higher than the low clean area, lower than the high clean area), block the infiltration of polluted air, to avoid external dust or microorganisms into the clean area. Double-door interlock mechanism: both sides of the door can not be opened at the same time, to prevent the direct circulation of unpurified air, in line with GMP specifications. 4. Reduce manual maintenance costs Automated operation: The self-cleaning function does not require manual intervention, reducing frequent cleaning and disinfection operations and saving labor costs. Long-term filtration design: The H14 high-efficiency filter has a long life (usually 1-2 years), combined with differential pressure monitoring prompts to replace, to avoid excessive maintenance. 5. Adapt to complex scenarios Modular expansion: can be customized work table, non-power roller, differential pressure meter, and other functions, to meet different delivery needs (such as medicine, and electronic components). Space flexibility: Compact, can be embedded in the wall or installed independently to accommodate clean room layout constraints. 6. Compliance and reliability Industry-standard adaptation: In line with the new GMP, ISO 14644, and other specifications, through third-party certification (such as Su Xin STI testing), to ensure that the data can be traced. Stability verification: Some models support airflow pattern testing and self-cleaning time verification to meet the verification needs of pharmaceutical companies. Sum up The self-cleaning function of the laminar flow transfer window significantly improves the safety and operation efficiency of clean areas through the combination of "active purification + passive protection", especially for biopharmaceuticals, high-precision electronics, and other areas that are highly sensitive to pollution, helping enterprises reduce compliance risks and ensure product quality. |
