Frequently Asked Questions
Q: Why is the extra-large 1220X620mm size critical for ISO 4-8 cleanrooms?
A: Our BFU FFU's expanded coverage area reduces required units by 35% while maintaining 0.45m/s ±3% airflow uniformity across the entire cleanroom ceiling. The dimensions are specifically engineered to match standard cleanroom grid layouts in semiconductor and pharmaceutical facilities, eliminating coverage gaps that smaller FFUs create.
Q: How does the tool-free filter change system improve cleanroom operations?
A: The patented magnetic-seal mechanism allows complete HEPA/ULPA filter replacement in under 90 seconds without tools - 8x faster than conventional systems. This eliminates: particulate release during maintenance 85% of cleanroom downtime for filter changes All need for technician recertification after maintenance
Q: What makes your ultra-low vibration system essential for advanced manufacturing?
A: The active vibration cancellation system maintains vibration levels (10x better than standard FFUs), which is crucial for: EUV lithography equipment (prevents mask misalignment) Electron microscopy (ensures imaging accuracy) Quantum computing labs (maintains qubit stability) Our system continuously monitors and adjusts 200x/second using piezoelectric actuators.
