DC EFU | Modular Energy-Saving Air System for Data Centers | Ultra-Low Noise & Smart IoT Control

The DC EFU 1170X1170X110+35 redefines precision air filtration for hyperscale data centers, server farms, and edge computing facilities, combining a patented modular design with direct current (DC) ultra-high efficiency. Featuring a two-tier 110+35mm stackable chassis, this EFU delivers 2200 CMH airflow at just 42dB(A) while achieving 99.999% H14 HEPA efficiency for ISO Class 3-5 environments. Its IoT-enabled predictive maintenance and hot-swappable filter trays ensure zero downtime in 24/7 critical operations, compliant with ASHRAE TC9.9 and TIA-942 standards.

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.
