EXT CLASS 1 Biohood

Our EXT CLASS 1 Biohood provides the highest level of operator and environmental protection from harmful particulates available today. Quality materials, components and workmanship normally associated with high-end models can be found in all of our cost-effective EXT series hoods.


Key Features
  • Operator Protection
    The airflow is directed away from the operator, into the hood to be filtered. Each EXT size 
    has been successfully ASHRAE 110 tested with excellent results.
  • Particulate Filtration
    The CLASS 1 model filters the contaminated air through a HEPA filter, rated 99.99% efficient at 0.3 microns.
  • Independent Operation
    Internal fans direct the air without being ducted to the building system and vent the filtered air back into the room.
  • Corrosion Resistant
    Constructed from corrosion-resistant white polypropylene, these hoods are ideal for processes involving corrosive chemicals and are resilient to frequent sanitizing.
