A ductless fume hood is a contained working space that uses powerful negative airflow to pull harmful fumes, vapors or particulate away from the operator’s respiratory zone and protects the operator and the environment from exposure.
How does a Ductless Fume Hood work?
Ambient Air is drawn into the hood and mixed with fumes, vapors or particulates emitted from the process.
The air within the hood is processed through a pre-filter where some particles are captured.
Air is filtered through the main filter (HEPA, ULPA, ASHRAE, Activated Carbon or Specialty Blended).
Filtered air is released back into the room eliminating the need for duct work.
