Esco Ascent Ductless Fume Hoods provide protection to both laboratory
personnel and the environment from toxic fumes and are quickly becoming a
viable alternative to conventional fume hoods. Unlike conventional fume
hoods, these hoods filter out chemical fumes and recycle air directly
back to the laboratory, providing energy savings, personnel and
environmental protection, convenience as you do not have to deal with
complicated ducting systems, and mobility, since ductless hoods are
independent systems which do not require connection to extraction
systems.
