A ductless fume hood is a device which recirculates filtered air from a hood or enclosure directly back into the working environment. These hoods are unique in that the contaminated air is not vented to the outside through a system of ducts, unlike conventional fume hoods. The objective of the filtration system is to reduce the levels of solids, gaseous or vapor constituent to that below the...

Ductless fume hoods are ventilated cabinets often used in laboratories to control the release of harmful or toxic fumes. In addition, they help keep the work area safe, prevent airflow from being blocked by a closed door, and improve accessibility to the work area.Activated by opening the door, a portable ductless fume hood creates airflow over hazardous materials when the external door is...
