Fume
Hood
The
PP
ductless
fume
hood
is
a
self-contained
laboratory
ventilation
cabinet
designed
for
safe
handling
of
chemical
vapors
and
hazardous
gases
without
external
ducting.
It
uses
a
built-in
fan
and
high-efficiency
chemical
filtration
system
to
capture
and
filter
contaminants,
protecting
operators
and
the
laboratory
environment.
Constructed
from
corrosion-resistant
PP
polypropylene
and
optional
stainless
steel,
the
fume
hood
is
suitable
for
GMP
laboratories,
cleanrooms,
teaching
labs,
and
analytical
laboratories.

Principle
1.
Dirty
room
air
is
drawn
into
the
front
of
the
fume
hood.
2.
Room
air
mixes
with
potentially
contaminated
air
from
chamber
and
is
pulled
upward
by
the
bulding
exhaust.
3.
Air
split
at
back
of
hood
increases
exhaust
and
reduces
turbulence.
4.
Contaminated
air
drawn
from
fume
hood
by
building
exhaust
fan
and
leaves
through
air
stacks
on
