THE GREEN LINE SERIES - OIL MIST SEPARATORS WITH HIGH PURIFICATION, LOW MAINTENANCE
AND OUTSTANDING OPERATION ECONOMY
THE TECHNOLOGY

OPERATING PRINCIPLE

1

Liquid to gas separation technology was invented
over 100 years ago. Based on that technology, 3nine
has been developing oil mist separators since 2001.
In 2009, 3nine started developing a totally new
concept and technologies that would further change
the way oil mist would be eliminated in the shop.

The GREEN LINE series of units separate 100%
of all fluid particles down to 1 µm, 91% down to
0.9 µm and 82% down to 0.75 µm. In order to
capture the finer particles that are <1µm, 3nine
uses a HEPA filter (H13) to ultimately clean the air
to 99.97%. With most of the particles separated
in the disc stack, only 1% of the particles are
collected in the HEPA filter.

CIP: Automated cleaning
system that
keeps the
rotors clean

The GREEN LINE Series utilizes one
rotor and disc stack size for all the units.
One rotor develops 300m3/h. When
a higher flow rate is required we add
another rotor to the separator. This
facilitates scalability for different airflow
requirements. The rotors are spun by a
motor and drive belt.

1 COUNTER FLOW TECHNOLOGY
The GREEN LINE units are based on Counter Current
Technology. Each rotor has a fan at its top, which
along with the spinning disc stack, creates the
suction and pulls the processed air in from the
machine tools’ cabin. This combination creates the
pre-separation of the larger particles down to 10µm.
This makes it extremely efficient for all applications,
including difficult applications such as grinding or die
casting with emulsions.

Our goal was to bring oil mist elimination to a new
level, develop products that were well adapted for all
applications using either oil or coolant and to simplify
the monitoring of the products through visual and
digital communication. The new series, called the
abscheidung durch
GREEN LINE, is based on Multi-Rotor and Counter
Tellerseparation
Current Technologies. Multi-Rotor technology
facilitates scalability which allows for the many
aufgefangen im
airflow requirements and Counter Current Technology
HEPA-Filter
allows each unit to work with all machining
applications using either oil or coolant.

Fluid particles smaller than 10 µm, will enter the disc
stack to be further separated to 100% down to 1µm.
On the discs, the small particles coalesce and form
larger particles. The bigger the particle, the faster
they move towards the edge of the spinning disc
to be thrown off and onto the inner wall of the rotor
chamber to be returned to the machine tool for reuse.

3 FINAL STAGE HEPA FILTER H13
The particles smaller than 1µm, will be collected by
the final stage HEPA filter. With most of the particles
separated in the rotor, the HEPA filter has a life
expectancy of 12-18 months*. The final stage HEPA
filter is a grade H13 and produces 99.97% particle
free air.

CLEAN IN PLACE (CIP)
“YOUR MAINTENANCE PARTNER”
With our CIP (Clean in Place) particle buildup
on the rotor is avoided. The CIP system uses
clean cutting fluid from the machine tool to
automatically and continuously clean the
rotors. With the GREEN LINE Series the
rotor can go through a cleaning cycle automatically at every startup and shutdown of the unit.

* 12-18 months filter life is based on 1 shift per day, 5 days a week and normal operating conditions.

LED-COMMUNICATION
All GREEN LINE oil mist separators have a built in
system control box. The control box monitors and
reports on the HEPA-filter status and the status of
the airflow. The status of the machine is then
communicated through a LED RGB-strip on the front
and back of the machine.

SECURE WORKING
ENVIRONMENT
Oil mist exposure can cause severe health issues
for the operator. If not handled properly, the oil
mist will coat the surfaces in the shop, causing
risk of injuries by slippery surfaces, an increased
need of cleaning and damages on electrical
devices. With an oil mist separator from 3nine,
this will not be a problem. The air coming out of
a GREEN LINE oil mist separator is
so clean that it can be recycled
right back into the workshop
and guarantees an optimal
working environment for
the operator.
