They said they couldn't do it, so we built it.


Our EXT Chemical Extraction Hoods also know as a 'Ductless Fumehood" provides you with the highest level of operator and environmental protection from harmful chemicals 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.
  • Chemical Filtration: The ‘Ductless Fume Hood’ model filters the contaminated air through a chemical filter that is specific to the use of the hood.
  • Independent Operation: ​​​​​​​Internal fans direct the air without being ducted to the building system and recirculates 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.
