Safety and Protection

  • HEPA filters guarantee maximum filtration efficiency of 99.995% at the most penetrating particle size (MPPS)
  • Segmented H14 HEPA filter system directly below work area protects inner air ducts, plenums and fans; provides a cumulative filtration efficiency of 99.99999975% to downflow and exhaust airflow
  • 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
  • Independent alarm system 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


  • Motorized front window with adjustable 20cm working aperture slopes 10°
