Ductless Fume Hoods

Ductless fume hoods pass contaminated air through filters before returning air to the room. Use for locations where outside ventilation cannot be achieved. A ductless fume hood can eliminate very high percentages of particulates and biological hazards to protect lab workers and the lab environment. When deciding if you need a ductless fume hood, take into consideration physical installation requirements and the materials or chemicals you are using.
