Class II Type A2, NSF49

AIRTECH brand biological safety cabinet class IIA2 certified to NSF49 is designed to protect operator, laboratory environment and samples from being exposed to the infective aerosol produced when the sample is bacteria strains, diagnostic material, and other infective subjects. AIRTECH biological safety cabinet provides the operators with a more comfortable and safer working condition. It is used in hospitals, disease prevention center, biological pharmacy and environment monitoring sections.

Control System

    Large control panel displays valuable safety and performance data, and is within easy view and reach from a seated position.

    Intuitive interface delivers a constant read-out of downflow and inflow velocities and overall cabinet performance status.

    Various of inter lock design to avoid risks due to misoperation.

“Zero Leakage” Airflow System

    AIRTECH unique “Zero Leakage” patent technology, providing a dynamic negative pressure environment.

    Imported DC ECM blower with automatic air volume compensation system to guarantee stable negative pressure.

    Two independent sets of imported velocity sensors.

    70% dowflow, 30% exhaust.

    Optional exhaust canopy connecter approved by NSF 49.

Humanization Design

    Up to 45% reduced energy consumption by using of DC ECM blower and optimized airflow system.

    Reduced Noise Level. Lower noise level enhances the attention and allows user to focus on work without distraction.

    Dwyer brand (US imported) pressure gage indicates real-time negative pressure between two sides of down flow filter.  

    Single piece wall & work tray: Large radius for easy cleaning. Made in SUS304, rust free.

    10° sloped front for enhanced comfort and reduced operator fatigue.

    Two Electric sockets. Waterproof & overload protection.

    Adjustable feet to fit uneven floor, casters for easy movement.

    Drain valve for convenient cleaning.
