AIRTECH BSC-05IIA2 Series Class II Type A2 Biological Safety Cabinet

Overview

The AIRTECH BSC-05IIA2 Series is a CE- and ISO 14644-compliant Class II, Type A2 biological safety cabinet engineered for reliable personnel, product, and environmental protection in microbiological, pharmaceutical, and clinical laboratory environments. It operates on the principle of inward airflow (70% recirculated through a dual-stage HEPA filtration system, 30% exhausted externally via dedicated ducting), maintaining negative pressure within the work chamber while delivering ISO Class 5 (Class 100) laminar downflow across the work surface. The cabinet conforms to NSF/ANSI 49–2022, EN 12469:2000, and GB/T 16292–2010 standards for performance verification, including containment integrity testing at 500 Pa static pressure, airflow velocity mapping, and filter leak detection per EN1822-1.

Key Features

• 7-inch capacitive touchscreen interface with real-time display of inflow velocity (0.30–0.50 m/s), downward airflow velocity (0.25–0.35 m/s), and differential pressure across supply/exhaust HEPA filters — all calibrated per ISO 14644-3 Annex B.
• Brushless DC constant-air-volume (CAV) blower system with digital speed control, ensuring stable airflow under variable sash positions and filter loading conditions; includes energy-saving mode (30% power reduction) when sash is fully closed and risk assessment permits.
• Ergonomic front panel inclined at 10°, combined with wide-radius stainless steel armrests and seamless SUS304 work chamber (electropolished finish), minimizes operator fatigue and enhances self-cleaning capability.
• 6 mm UV-blocking tempered glass sash with frictionless linear lift mechanism — eliminates counterweight maintenance and enables full-height cleaning without visual obstruction.
• Dual HEPA/ULPA filtration architecture: supply air passes through an H14-rated (≥99.995% @ 0.3 µm) filter; exhaust air is treated by a second H14 or U15 filter prior to ducted discharge. All filters undergo 100% factory scan-testing per EN1822-3.
• Integrated grid-type debris barrier above the front grille prevents entry of disposable lab waste into the plenum; optional pre-filter module available for high-particulate environments.
• Multi-level access control: three-tier password system (operator, supervisor, service technician) aligned with GLP audit requirements; RS485 Modbus RTU port supports integration into centralized lab monitoring systems.

Sample Compatibility & Compliance

The BSC-05IIA2 Series accommodates standard biosafety Level 1–2 agents (e.g., E. coli, S. aureus, adenovirus) and select low-risk BSL-3 procedures when used with supplemental PPE and facility engineering controls. Its structural integrity has been validated per IEC 61010-1 for electrical safety and EN 61326-1 for EMC immunity. Cabinet leakage testing complies with NSF/ANSI 49 Section 7.3.2 (≤0.01 CFU/min aerosol challenge), and airflow uniformity meets ISO 14644-3 Class 5 criteria (±15% velocity deviation across work surface). Optional UV lamp (254 nm, 15 W) is installed in a shielded forward position to minimize ocular exposure during activation.

Software & Data Management

The embedded firmware logs operational parameters (sash height, runtime, filter delta-P, alarm events) with timestamped records stored onboard for ≥12 months. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records — including user authentication, action logging, and non-erasable event history. Data export is supported via USB-C or RS485 to LIMS-compatible platforms. Firmware updates are performed via secure signed package verification; configuration backups can be scheduled automatically.

Applications

• Molecular biology workflows: plasmid transfection, PCR setup, and CRISPR reagent handling where cross-contamination must be prevented.
• Pharmaceutical QC labs: aseptic sampling of sterile injectables, media fill simulations, and microbial limit testing per USP and EP 2.6.12.
• Clinical diagnostics: processing of patient specimens for culture, serology, and nucleic acid extraction under CLIA- and CAP-aligned containment protocols.
• Vaccine development: handling of attenuated viral vectors and adjuvant formulations requiring simultaneous personnel and product protection.
• Cell therapy manufacturing: open manipulation of primary human cells in GMP Annex 1-compliant cleanroom support zones.

FAQ

What certification standards does the BSC-05IIA2 meet?

It is independently verified to NSF/ANSI 49–2022, EN 12469:2000, and GB/T 16292–2010 for airflow performance, containment, and filter efficiency.
Can this cabinet be ducted to an external exhaust system?

Yes — Type A2 configuration requires hard-ducted exhaust with canopy or thimble connection; minimum exhaust flow rate is 760 m³/h (450 CFM) depending on model size.
How often should the HEPA filters be replaced?

Filter service life is monitored continuously via differential pressure sensors; replacement is triggered when ΔP exceeds 750 Pa (typical lifespan: 5–7 years under normal use with pre-filtration).
Is the UV lamp ozone-free?

Yes — the low-pressure mercury lamp emits exclusively at 254 nm with no detectable ozone generation (<0.01 ppm), compliant with OSHA PEL guidelines.
Does the cabinet support remote monitoring via Ethernet or Wi-Fi?

Native Ethernet/Wi-Fi is not included, but RS485 output allows integration with third-party building management systems (BMS) or SCADA networks using protocol converters.
