How To Select The Ideal FFU for Your Cleanroom: Deshengxin's Expert Guide

How to Choose the Right FFU for Your Cleanroom? Deshengxin's Professional Guide

In industries like semiconductors, biopharmaceuticals, and precision electronics, FFU (Fan Filter Unit) serves as the cornerstone of maintaining air cleanliness in controlled environments. With over 20 years of expertise in cleanroom technology, Deshengxin understands that selecting the ideal FFU requires balancing performance, cost, and long-term maintenance. This guide breaks down critical factors to help you optimize your cleanroom solutions.

1. Define Cleanroom Class & Requirements

FFU selection must align with ISO 14644 cleanroom classifications:

• ISO Class 5 (FS 209E Class 100): Requires FFU coverage of 60-80% with ≤±15% airflow uniformity.

• ISO Class 7 (FS 209E Class 10,000): Lower coverage suffices, but airflow organization must prevent contamination.

2. Core Parameters: Airflow, Velocity & Noise

• Airflow (CMH): Calculate based on room volume and air changes/hour (e.g., 100㎡ cleanroom needs ≥5,000 CMH).

• Velocity Uniformity: Premium FFUs like Deshengxin’s achieve ≤±10% variation for consistent particle control.

• Noise Levels: Our FFU models feature brushless DC motors, operating at ≤55dB for noise-sensitive environments.

3. Filtration Efficiency & Energy Optimization

• HEPA vs ULPA:

• H13 HEPA (99.97% efficiency) suits most industrial applications.

• U15 ULPA (99.9995% efficiency) meets semiconductor/life science standards.

• Energy Savings: Deshengxin’s FFU systems integrate smart inverters, reducing energy consumption by 30% vs conventional units.

4. Material Quality & Durability

• Housing: 304 stainless steel or galvanized aluminum for corrosion resistance.

• Sealing Technology: Dual EPDM gaskets ensure <0.01% leakage rates.

• Maintenance: Modular design allows swift filter replacement, minimizing downtime.

5. Why Choose Deshengxin?

• Customization: Non-standard sizes (up to 1200×2400mm) and specialty features (explosion-proof, low-vibration).

• Certifications: ISO 9001, CE, and TÜV-certified for global compliance.

• Local Support: 12 service centers nationwide, 24/7 emergency response, and lifetime technical guidance.
