High-Performance Low Noise Pass Boxes for Lab Environments

I. Core Technical Highlights

1. Dual Sterilization Purification

    

   Equipped with UV germicidal lamp and HEPA two-stage purification, UV quickly kills surface microorganisms, HEPA thoroughly intercepts particles, ensuring material surface and transfer air meet Class 100, eliminating cross-contamination. Ordinary pass boxes only have physical isolation.
    
2. Low-Noise Operation Design

    

   Low-noise fan and optimized air duct, low noise, low power, 30% noise reduction and 25% energy saving than traditional models, avoiding interference with precision experiments. Mechanical/electronic interlock, doors cannot open simultaneously, preventing airflow leakage.
    
3. Ready-to-Use

    

   No complex installation, out-of-box use, compact size, quickly embeds walls of different thicknesses, customizable specifications. SUS304 stainless steel, double tempered glass windows, seamless and protrusion-free, withstands frequent alcohol / hydrogen peroxide disinfection. Fixed models cannot adapt to complex walls.
    
4. Full-Life-Cycle Cost Optimization

    

   Long machine life, short filter and UV lamp replacement cycle, maintenance every six months. Seamlessly connects with air showers and laminar flow hoods, 40% lower long-term cost than ordinary pass boxes.
    

II. Quick Selection Guide

• Biosafety Laboratories / Vaccine Production (ISO 1–5): Dynamic pass box with HEPA + UV + MES, for high-risk materials.
• Pharmaceutical R&D / Medical Device Testing (ISO 6–7): Standard with UV + HEPA + interlock, for aseptic materials.
• General Laboratories / Electronic R&D (ISO 8): Static pass box with UV + interlock, for routine materials.

III. Installation Process

1. Confirm wall opening matches outer size, reserve 220V power.
2. Embed pass box into wall, seal gaps with cleanroom silicone.
3. Connect power, test interlock, UV and HEPA.
4. Pass particle test for cleanliness, train operators and sign acceptance.

IV. Daily Usage Notes

1. Check UV lamp and HEPA pressure difference weekly; replace filters if pressure difference exceeds standard.
2. Wipe interior and door with 75% alcohol in one direction; do not scrape stainless steel.
3. Stop use immediately for interlock failure or abnormal noise; use original parts.
4. Avoid heating equipment nearby; turn off power and cover windows before fumigation.
