Cleanroom air purification in pharmaceutical, electronics, and biotechnology facilities.
Manufacturing zones requiring ISO-certified filtration with high-volume airflow (2000 m³/h).
Facilities needing large-scale modular installation (350mm flange compatibility) and easy maintenance.
70% reduction in ceiling penetrations (1 unit replaces 4 standard FFUs), minimizing contamination risks
Unmatched airflow uniformity (<±0.15% velocity variation) across entire photolithography bays
Integrated service rails allow robotic filter changes without breaking cleanroom protocols (ISO Class 1 maintained throughout maintenance)
Auto-sealing NanoGasket™ maintains negative pressure during filter swaps
Precision-guided robotics complete ULPA changes in 110 seconds (vs. 30+ minutes manual)
Smart particle counters automatically validate filter integrity post-service, eliminating traditional 4-hour re-qualification downtime
AMC control: Activated carbon layer removes airborne molecular contaminants
Nanoparticle capture: Superior capture of critical particles (critical for <3nm node yield)
Vibration elimination: Magnetic levitation achieves vibration reduction - 10x better than ASML's requirements
