In 2025, cleanroom standards continue to evolve, demanding precision-engineered FFUs (Fan Filter Units) to meet stringent ISO 14644 and industry-specific requirements. Whether for semiconductor fabrication, biopharmaceutical production, or electronics manufacturing, selecting the right FFU impacts operational efficiency, compliance, and long-term ROI. Deshengxin, a leader in cleanroom technology since 2005, breaks down the critical steps to optimize your FFU selection.
1. Align with Cleanroom Classification Standards
ISO 14644-1:2025 Updates
- ISO Class 5 (FS 209E Class 100):
- ISO Class 7 (FS 209E Class 10,000):
Deshengxin’s 2025 Recommendation:
Request a free cleanroom assessment to receive a tailored FFU layout plan, including 3D airflow simulations for optimal performance.
2. Core Technical Parameters
Airflow & Velocity
- Airflow (CMH):
Calculate based on:
Room volume × Air changes/hour (ACH).
Example: A 100㎡ cleanroom with 50 ACH needs
≥5,000 CMH.
- Velocity Uniformity:
Deshengxin’s FFUs achieve
≤±10% uniformity, ensuring stable laminar flow.
Noise Control
3. Filtration Efficiency: HEPA vs. ULPA
| Filter Type | Efficiency | Applications |
| H13 HEPA | 99.97% @ 0.3μm | Pharma, Hospitals, Food |
| U15 ULPA | 99.9995% @ 0.12μm | Semiconductors, Nanotechnology |
Energy-Saving Tip:
Deshengxin’s Smart Inverter FFUs reduce energy use by 30% via real-time airflow adjustments.
4. Material Durability & Compliance
- Housing:
304 stainless steel or galvanized aluminum (resists corrosion from chemical vapors).
- Sealing:
Dual EPDM gaskets ensure
<0.01% leakage (exceeds ISO 14644-3:2025 standards).
- Maintenance:
Modular design allows
5-minute filter replacement without disrupting operations.
5. Why Deshengxin Leads in 2025 FFU Innovation
- Custom Solutions:
FFUs up to
1200×2400mm for non-standard cleanrooms.
- Global Certifications:
CE, ISO 9001, and IEST-recommended practices.
