□
Ambient
temperature
Temperature of
substances to be
suctioned into the
collector
0°C - 40°C
□
Be sure to only use
the collector for
collecting oil mist.
The collector should
not be used to collect
dust.
The collector should not
be used to collect oil mist
that contains a large
amount of dust (1% or
more in weight ratio).
□
The collector should
not be used to
collect combustible
materials.
Explosive oil mist
containing combustible
dust should not be
suctioned into the
collector.
Carbon, magnesium,
aluminum, etc.
□
The collector should
not be used to
collect inflammable
substances.
Never allow oil with a
flash point below 80°C
to be suctioned into the
collector.
Gasoline,
paint
thinner, solvent mist,
etc.
□
Mist generated from
metalworking
operations
The collector should
not be used to
collect adherent
substances.
High-viscosity mist
should not be
suctioned into the
collector.
Mist of oil used to cook
meat, etc.
□
Mist that has an
appropriate pH value
The collector should
not be used to
collect alkaline oil
mist with a high pH
value.
Range of application:
pH 7.0 to 10.5
The collector should
not be used to collect
strongly acidic mist,
strongly alkaline mist,
or corrosive mist.
□
Electrical
conductivity of mist
to be collected
The collector should
not be used to
collect mist with high
conductivity.
The collector should be
used to collect mist with
electrical conductivity
below 300 mS/m.
□
Take in secondary air to
control the
concentration.
□
Substances
the collector
can suction
Concentration of
mist permitted to be
suctioned
Oil mist that has a
concentration over
the specified level
will cause oil mist to
leak from the
exhaust port.
The maximum
permitted suctioning
density is 200 mg/m
3
.
Use an optional
eliminator to control the
concentration.

connecting ductwork (Page 12)
Important
Be sure to observe the following to prevent malfunctions:
- The collector should not be used to collect water (vapor).
