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,
as
ductless
hoods
are
independent
systems
which
do
not
require
connection
to
extraction
systems.
Esco

independently
tested
by
INVENT
