FAQ :
1. How does the dual-fan design ensure uninterrupted airflow in critical pharmaceutical environments?
The dual-fan redundancy guarantees continuous operation—if one fan fails, the second automatically compensates to maintain ISO 14644-1 compliance, preventing costly production halts or contamination risks in sterile drug manufacturing.
2. What certifications and filtration standards does this FFU meet for GMP-grade cleanrooms?
Equipped with pharmaceutical-grade H14 HEPA filters (99.995% @0.3µm), it exceeds EU GMP Annex 1 and FDA CFR 210/211 requirements. Each unit is ISO 9001/CE certified, with optional PQ/OQ validation support for audit readiness.
3. How is the system optimized for 24/7 operation in energy-sensitive facilities?
Smart power management: Dual EC motors reduce energy use by 30% vs. traditional AC fans, with <150W power draw per fan.
Predictive maintenance: Built-in vibration sensors and RS485 alerts notify teams of filter clogs or motor issues before failures occur.
