Be sure to read and understand on the page 3 to 7 “For safety operation” carefully before use
Installing ducting
●
Requirements for connecting ductwork
Make sure that the following requirements for connecting ductwork are satisfied to ensure safe
operation and that the collector delivers maximum performance.
Requirements Items to be checked Notes Remarks (1) Remarks (2) Checked
☑
Duct
materials
Consideration of the
oil to be handled
The use of oil proof ducts
is recommended for oil
(water-insoluble) mist.
Less prone to
becoming hardened
by oil.
□
Avoid using a duct with
an unnecessarily small
diameter.
A duct with an
inappropriate diameter
causes insufficient
airflow rate.
Insufficient airflow rate
may cause collection
performance to
deteriorate.
□
Duct diameter Securing of a duct of
the appropriate
diameter
Recommended
diameter of duct
EM-15eII: 150 mm or
larger
EM-30eII: 200 mm or
larger
□
Securing of joints Secure the duct joints
using hose bands or any
other types of clamps.
Caulk any gaps in the
joints.
□
Do not allow the duct
to sag.
The duct should take
the shortest path.
Do not let mist accumulate
inside the pipe.
□
Minimized duct
resistance
The interflow part
should be smooth.
A supplementary
explanation is provided
on the next page.
□
Connecting
ductwork
Measures to prevent
backflow of oil mist.
Connection of exhaust
ports of multiple mist
collectors to an
interflow pipe
Exhaust backflow into
a mist collector that
has stopped operating
may occur.
□
Prevention of foreign
substances (chips)
being suctioned into
the collector
Install a battle plate on
a machine tool.
□
Battle plate
Control of
concentrations of mist
Install a battle plate on
a machine tool.
The splay of oil may
enter the collector.
Where oil mist exists
in high concentrations
□
Prevention of foreign
substances (chips)
being suctioned into
the collector
Position the ductwork
away from the mist
source.

location
Control of
concentrations of
mist
Position the ductwork
away from the mist
source.
The splay of oil may
enter the collector.

□
Securing of
appropriate airflow
rate
An error resulting from
insufficient airflow rate
is displayed.
Intake of secondary
air
Please contact our
sales representative.
□
Intake of
secondary air
Control of
concentrations of
mist
Oil mist exists in high
concentrations,
causing oil mist to leak
from the exhaust port.
Intake of secondary
air
Please contact our
sales representative.
