Created on 01.12
Overview of Laminar Flow Pass Box
Laminar flow pass-through windows are critical equipment for transferring items between cleanrooms and external environments. Through high-efficiency air filtration systems and scientific design, they prevent cross-contamination while transferring items. This article provides a detailed analysis of the 6 core components of laminar flow pass-through windows, explaining the functions of each component and their impact on equipment performance and service life.
Door System
Laminar flow pass-through windows feature electronically interlocked upward-opening door design, enabling item transfer between different floor levels while minimizing contamination of clean areas.
- Electronic interlock design ensures both doors cannot open simultaneously
- Excellent airtightness to prevent air leakage
- Smooth opening/closing mechanism reduces vibration impact
- Made from durable, corrosion-resistant and anti-aging materials
⚙️Impact on Performance & Lifespan
High-quality door systems ensure airtightness, maintain stable pressure differentials, directly affecting cleanroom maintenance capability. Durable materials and precise construction reduce wear, extending overall equipment lifespan.
HEPA/ULPA Filter
The high-efficiency filter is the core purification component of laminar flow pass-through windows, providing unidirectional laminar airflow to ensure internal cleanliness reaches ISO Class 5 or higher standards.
- Filtration efficiency above 99.99% (for 0.3μm particles)
- Uniform airflow distribution reduces turbulence
- Low airflow resistance design for energy efficiency
- Easy replacement and maintenance design
⚙️Impact on Performance & Lifespan
Filter quality determines cleanliness levels, directly affecting contamination risks of transferred items. Regular maintenance and replacement ensure long-term performance stability, preventing motor overload and increased energy consumption due to clogging.
Electronic Interlock System
The electronic interlock system ensures both doors cannot open simultaneously, effectively preventing direct airflow between clean and non-clean areas while maintaining stable pressure differentials.
- Dual-door interlock ensures safety isolation
- Status indicators and audible alerts
- Emergency unlock function
- Programmable control logic
⚙️Impact on Performance & Lifespan
Interlock system reliability directly affects clean area contamination protection. High-quality electronic components and proper programming reduce failure rates, extending control system lifespan.
UV Disinfection System
Equipped with UV probes to ensure required irradiation dosage for disinfection, providing more thorough sterilization and cleaning of transferred items.
- Intelligent UV probes for precise irradiation monitoring
- Automatic timer start/stop function
- Safety interlock automatically turns off UV lights when doors open
- Lamp life monitoring and alarm functions
⚙️Impact on Performance & Lifespan
UV system effectiveness directly impacts sterilization results. Probe monitoring ensures adequate irradiation dosage, extending lamp life while guaranteeing disinfection effectiveness and preventing inefficient operation.
Airflow Control System
Equipped with weight sensors for automatic airflow adjustment, making operation more convenient. Intelligently adjusts air velocity and volume based on size and weight of transferred items.
- Weight sensors automatically detect items
- Variable frequency fans for energy saving and noise reduction
- Real-time air velocity monitoring and display
- Automatic air pressure balance adjustment
⚙️Impact on Performance & Lifespan
Intelligent airflow control reduces fan load, extends motor life, and ensures cleanliness requirements in different scenarios. Energy-saving design reduces operating costs and improves equipment economy.
Control & Monitoring System
Integrated intelligent control system enables status monitoring, fault alarms, data logging, and remote management functions.
- Touchscreen human-machine interface
- Real-time monitoring of pressure differentials, air velocity, temperature
- Operation data logging and export
- Network communication and remote monitoring interfaces
⚙️Impact on Performance & Lifespan
Intelligent control systems enable preventive maintenance, identifying potential issues early to reduce sudden failures. Data logging provides basis for optimizing operations, extending equipment effective service life.
💡Value of Core Component Synergy
The 6 core components of laminar flow pass-through windows don't work in isolation but achieve overall performance optimization through precise coordination. For example:
- Door system and interlock system
- Weight sensors and airflow control system
- UV disinfection system and control system
- Filters and airflow control
This synergistic design not only enhances the performance reliability of laminar flow pass-through windows but also significantly extends overall equipment service life by reducing unnecessary wear between components.
