Different Sizes FFUs Refer To Different Application Scenarios And Technical Requirements

Application Scenarios and Technical Requirements for FFUs with Different Sizes‌

‌1. Standard Size (1175×575mm)‌

• ‌Application‌: General cleanroom environments (ISO Class 5-8) in electronics manufacturing and standard laboratories.
• ‌Technical Parameters‌: Airflow 1000 m³/h, wind speed 0.45 m/s ±20%, noise ≤55 dB, power 120 W.
• ‌Features‌: Compatible with mainstream ceiling grid systems, cost-effective, suitable for large-scale cleanroom modular layouts.

‌2. Large Size (1175×1175mm)‌

• ‌Application‌: Ultra-clean environments for advanced semiconductor manufacturing (e.g., 5nm production lines) and lithography equipment (ISO Class 1-2).
• ‌Technical Parameters‌: Airflow 2200 m³/h, ULPA efficiency 99.9995% @ 0.12μm, with variable frequency speed control.
• ‌Features‌: Requires liquid-sealed design for airflow uniformity (0.45 m/s ±5%).

‌3. Custom Non-Standard Sizes‌

• ‌Application‌: Special cleanroom booths or unique industrial equipment (e.g., explosion-proof facilities).
• ‌Technical Parameters‌: Customized based on requirements, materials available in explosion-proof stainless steel or aluminum.
• ‌Features‌: Requires additional evaluation of static pressure (≥140 Pa) and harmonic interference issues.

‌Selection Recommendations‌

• ‌Electronics/Food Industry‌: Prioritize standard sizes for cost-effectiveness and compatibility.
• ‌Semiconductor/Pharmaceutical Industry‌: Choose high-static-pressure or ULPA-filtered medium/large FFUs.
• ‌Special Environments‌: Custom designs must consider material (e.g., S304 stainless steel) and explosion-proof requirements.
