  • duct. A front sash with glove ports may be installed. The exhaust air is passed through HEPA
  • filter before released in to the atmosphere. The cabinet unit is maintained under negative
  • pressure.
  • Air Balancing : Total exhaust cabinet with incineration


Class II - Type B : Recommended for Product & Personnel protection

Class II : Type cabinets differs in the proportion of air exhausted and re-circulated within the
cabinet; velocity of airflow to the work zone creates an ultra-clean environment for product
protection.

Class II - Type B

  • exhausted out through air incinerator for environmental protection. Velocity of airflow to the
  • work zone creates an ultra-clean environment for product protection.
  • Maintains a minimum measured average inflow velocity of 75 fpm through the work area
  • access opening. The face velocity at the access opening varies between 80 fpm and 100
  • fpm. Have HEPA filtered down flow air from a common plenum.
  • Air Balancing : 30% re-circulation and 70% exhaust.


Class II - Type B2
