IntroductionApplied in Biosafety Level 3 and above laboratories for rearing, experimental procedures and related operations on laboratory ferrets. Designed to meet biosafety and animal experimentation requirements.
ModelsFeatures- Single- or double-chamber configurations with multiple housing densities; independent control per chamber to avoid mutual interference.
- Parallel redundant exhaust units with automatic pressure-loss monitoring to maintain negative pressure; online fan replacement capability.
- Multi-stage exhaust filtration (mesh, primary, high-efficiency) with terminal H14 HEPA filters (99.995% MPPS per EN1822); automatic leak scanning, efficiency testing, in-situ disinfection and Bag-In-Bag-Out replacement.
- Front access with tempered glass viewing window, integrated glove sleeves and multi-point mechanical compression sealing.
- Ergonomic inclined front face for operator access.
- Rounded-corner rigid chamber construction with no burrs or cleaning dead zones; chamber leakage < 0.25% Vol/hr at -250 Pa.
- Each chamber includes an independent transfer chamber; optional disinfection methods: UV, pulsed xenon or atomized spray; reserved VH2O2 interface for external VHP or optional built-in VH2O2 system.
- Modular design allowing integrated or separate placement of chamber and control cabinet for space-constrained environments.
- Real-time monitoring of differential pressure, temperature, humidity and ammonia concentration.
- Built-in lighting and internal ferret cage racks for animal handling.
