1. Max. airflow is a ceiling value and generally not recommended as a
design value for operating the ME unit, as it might lead to short
lifespan of filters. The performance of the ME unit is next to airflow
influenced by other variables like amount and composition of metal
working fluid, process, temperature and pre-treatment. Ask your
local expert on the recommended airflow for your system design.

Operation
The extracted air contains oil mist that is released during
machine tool processes by impact with the machine tool or by
heat of a hot surface; in this case the liquid particles are
condensed from a vapour. Heat generated oil mist is often
referred to as smoke. The composition of oil mist depends on
the fluid and the process and can contain oil, water, metal fume
(evaporated and condensed metal), soot, metal particulate and
a variety of additives added to the metal working fluid.
The extracted oil mist enters the MistEliminator at the bottom
through the air inlet module. The inlet module distributes the air
and prevents large particles from entering the filter packages.
Subsequent filter stages:
General:
1
HydroFilter; impinger to separate oil droplets and coalesce
oil mist into droplets
2
Aluminium mesh pre filter to keep larger particles
ME-31 series:
3
Bag filter for main filtration
ME-32 series:
3
Bag filter for main filtration
4
HEPA filter for final filtration
ME-41 series:
3
OC-1 self-draining filter cassette that coalesces oil mist to
droplets and collects medium sized particles
4
OC-2 self-draining filter cassette that coalesces oil mist to
droplets and collects fine particles
ME-42 series:
3
OC-1 self-draining filter cassette that coalesces oil mist to
droplets and collects medium sized particles
4
OC-2 self-draining filter cassette that coalesces oil mist to
droplets and collects fine particles
5
HEPA filter for final filtration
The oil and other substances end up in the container
underneath.
If provided with a HEPA filter (ME-32 and ME-42 series), the
clean air can be recirculated in the workshop. Without HEPA
filter (ME-31 and ME-41 series) it is recommended not to
recirculate but to exhaust the filtered air to the atmosphere.
WARNING!
Check with local or state health & safety authorities on
recirculation regulations.
Differential pressure gauges on each filter module indicate when
the filters must be replaced.
2.2.1 OilPump (option)
The oil container with electric pump replaces the standard oil
container. It allows for automatic drain of oil to any other
O
collection device. It is operated by a level switch and can be
N
activated manually as well.
