Engineering Standards for Stainless Steel Interlocking Pass Boxes
Farclean pass boxes are built to meet rigorous cGMP, EU GMP, and ISO 14644 standards. Combining corrosion-resistant metal construction with advanced electronic door control ensures maximum operational safety and longevity:
- Grade 304 & 316/316L Stainless Steel Casing: Both internal chamber and external casing are constructed from high-grade stainless steel with polished #4 or hairline finishes, delivering high resistance to continuous chemical wiping and disinfectants.
- Microprocessor-Controlled Electronic Interlock: High-reliability electromagnetic locks prevent both doors from opening simultaneously. When one door opens, the opposite door automatically locks, preserving room pressure differential and isolating cleanroom zones.
- Radiused Coved Internal Corners: Internal chamber corners are fully seamless and curved (coved) with zero dead angles, preventing particle accumulation and allowing effortless sanitization.
- Flush-Mounted Double-Glazed Glass Doors: Dual-pane tempered safety glass windows sit completely level with the stainless steel door frame, eliminating dust-collecting edges while offering full visibility.
- Germicidal UV-C Disinfection: Equipped with an integrated UV lamp and customizable timer logic, ensuring automated surface decontamination between transfer cycles.
