Key Features
1. Robust Construction: Galvanized aluminum-zinc plate ensures superior durability and corrosion resistance.
2. High-Efficiency Motor: EBM DC 470 motor delivers stable, group-controlled airflow (0.45–0.75 m/s ±5%).
3. Advanced H13 Filtration: Non-partitioned HEPA filter (1170×1170×69 mm) achieves 99.995% efficiency at 0.3μm particles.
4. Precision Airflow Control: Group-controlled operation synchronizes airflow across large-scale cleanroom systems.
5. Low-Noise Design: Operates at 48–58 dB (tested 1.5m below filter), minimizing disruption in labs or production areas.
6. Vibration-Free Operation: <5μm peak vibration ensures compatibility with precision equipment.
Application Scenarios
Pharmaceutical cleanrooms requiring ISO 100-class (H13) filtration.
Semiconductor manufacturing with strict particulate control.
Biotechnology labs demanding stable airflow and low noise.
FAQ :
1,Q: How does DC power improve PUE in data centers compared to traditional AC FFUs?
A: Our 48V DC system eliminates AC/DC conversion losses, reducing power consumption by 18-22% per rack. Integrated with lithium-ion UPS backups, it maintains airflow during grid fluctuations—critical for Tier IV data centers requiring 99.995% uptime.
2,Q: Can the 110+35mm modular design adapt to legacy server racks?
A: Yes, the dual-height chassis allows:
35mm slim units for retrofitting existing 19" racks
110mm full-capacity units for new high-density deployments
Mixed configurations via tool-free magnetic coupling
3,Q: How does IoT integration prevent airflow disruptions in AI server clusters?
A: Embedded sensors monitor:
Real-time server heat loads (via thermal imaging)
Particulate levels (0.3μm resolution)
Filter pressure drop (auto-alerts at 90% capacity)
The system dynamically redistributes airflow within ±2% variance, preventing hot spots.
