Structural Design:
1. The vertical laminar flow negative-pressure system achieves 70% air recirculation plus 30% directional exhaust, equipped with zero-leakage HEPA/ULPA dual-effect filtration to maintain ISO Class 4-5 cleanliness.
2. The double-layer SUS304 stainless steel negative-pressure housing integrates a 4L fully sealed liquid collection tank. The inner liner, with its seamlessly formed rounded corners, combines leak-proof performance with self-cleaning properties.
3. The 10°-inclined operating surface, combined with a detachable hand rest, forms an ergonomic system, complemented by a maintenance-free, imported, height-adjustable glass front window (≥5mm).Intelligent Control:
1. The intelligent airflow compensation system ensures that when the filter resistance increases by 50%, the airflow fluctuation remains below 10%.
2. The Chinese-language human-machine interface provides real-time display of parameters such as wind speed, filter life, and operating time, and incorporates a dual-warning mechanism for both clogging and malfunctions.
3. Triple safety interlock: Front window limit switch with audible and visual alarm linked to lighting, UV sterilization interlock, and filter differential pressure protection.
Security Expansion:
1. The unobstructed return-air structure optimizes airflow organization, while the splash-proof power supply and multi-valve interface meet diverse experimental needs.
2. The imported fan works in conjunction with a multi-sealing system to achieve a stable intake air velocity of 0.2 m/s ±15%.Model HKHJ-1100IlA2-X HKHJ-1383llA2-X HKHJ-1500IIA2-X Cleanliness Level HEPA; ISO Class 5 (100 Class 100) / ULPA: ISO Class 4 (10 Class 10) Filter Category/Filter Efficiency HEPA: ≥99.995%, @0.3μm / ULPA: ≥99.999%, @0.12μm Downwind speed (m/s) 0.35 Inflow wind speed (m/s) 0.55 Noise (dB(A)) ≤65 Power supply AC220V/50HZ/1Ph Average airflow
