1. What are the key applications of the AC FFU 1175X1175X290 in data centers and semiconductor cleanrooms?
The AC FFU 1175X1175X290 is designed for environments requiring ultra-clean air, such as semiconductor fabrication facilities and data centers. Its high-efficiency filtration (99.99% @0.3μm H13) ensures minimal particulate contamination, critical for semiconductor wafer processing and server cooling systems. The unit’s modular design allows seamless integration into laminar flow systems, clean benches, or custom cleanroom layouts, ensuring uniform airflow and pressure control.
2. What technical specifications make this FFU suitable for heavy-duty industrial use?
Dimensions: 1175×1175×290 mm (compact yet robust for high-capacity airflow). Airflow: Up to 2000–2200 m³/h (adjustable via three-speed settings), ideal for maintaining ISO-classified cleanroom standards. Noise Level: ≤58 dB (tested 1.5m below the filter), ensuring minimal disruption in sensitive environments. Power Efficiency: Rated power ranges from 170–200W (±5W), optimized for energy savings while supporting continuous operation4. Material: Galvanized aluminum or coated zinc-aluminum plate for corrosion resistance and durability.
3. How does the design of this FFU simplify maintenance and enhance system longevity?
Bottom-Detachable Filter: Facilitates easy replacement of the non-partitioned H13 HEPA filter (1170×570×69mm), reducing downtime. Heavy-Duty Motor: Equipped with a high-performance motor (e.g., Nidec DC or MRJH models) rated for 30,000–50,000 hours of operation, ensuring reliability in 24/7 industrial settings. Modular Compatibility: Supports flange connections (e.g., D=350mm) and optional group control modules for scalable cleanroom systems.
