Safety and Protection

  • HEPA filters guarantee maximum filtration efficiency of 99.995% at the most penetrating particle size (MPPS)
  • Pressure sensor monitoring ensures safe airflow across the entire work surface
  • SmartFlow™ digital technology maintains constant airflow during normal filter loading or temporary airflow obstruction due to foreign objects
  • Digital Airflow Verification immediately alerts to any airflow obstruction

Performance and Operation

  • Interior eye-level display on rear wall for “at-a-glance” monitoring of safety parameters
  • Performance factor (PER) indicates: cabinet is safe, cabinet is safe but time for service, cabinet should not be used
  • Display parameters include downflow air velocity, cabinet malfunction, time of day, operating time of optional UV-C lights, total operating hours
  • Timer for delayed start
  • Stopwatch function
  • Handheld control for use inside cabinet eliminates glove changes before changing cabinet settings

Construction

  • Motorized front window with adjustable 25cm working aperture slopes 10°
  • DC motor technology uses energy efficiently with lower heat output
  • Aerosol-tight window sealing for additional protection when cabinet is in stand-by mode
  • Frameless front sash and side glass window yields unobstructed view of the total work area
  • Scratch-resistant stainless-steel work surface with indentations that trap spilled liquids

Certifications/Compliance

  • Independently tested and certified to EN 12469 standard for Class II biological safety cabinets by TUV Nord (230V models)
  • Compliant with NSF/ANSI™ 49 for Class II biological safety cabinets (120V models)
Ordering Information:

Adjustable stand options with electric or manual adjustment. Work surfaces available as single or segmented modules.
