INTRODUCTION
a)
Description
of
Product
The
oil
mist
eliminator
is
designed
to
separate
oil
droplets
and
contaminant
particles
in
the
exhaust
gases
emitted
by
oil~sealed
vaccum
pumps.
Since
the
2033
H and
2063
H pumps
are
used
to
pump
expensive
or
dangerous
substances,
the
hermetic
mist
eliminator
with
its
helium-tight
stainless
steel
housing
guarantees
excellent
tightness
(leakage
less
than
5 x 10-7
atm cc-sec™!),

OPERATING
PRINCIPLE
a)
Principle
When
operating
at
high
pressure,
forepumps
emit
an
oil
mist
entrained
by
the
gas
flow.
The
cartridge
in
the
eliminator
filters
the
gas,
trapping
the
oil
by
coalescence.
.
The
eliminator
captures
toxic
or
harmful
pumping
products
and
prevents
them
from
returning
to
the
pump
and
contaminating
it.
The
eliminator
can
also
be
used
for
applications
involving
expensive
lubricants.
