Air filters
Working principles
Polluted air is drawn in by a high efficiency
centrifugal fan (A), mounted behind the filters.
In this way the fan cannot be damaged, since
it works with clean air without any pollutant
residual.
Air passes initially through a special deflector
(B), whose function is to distribute uniformly
the air onto filter’s surface, assuring a proper
use of the whole useful contact area of the
filter.
Then the air crosses a series of filters with
increasing efficiency (C) up to more than
95% with polluted particles measuring less
than a micron. Efficiency can reach 99,97%
with the use of a HEPA post-filter following
EN 1822 regulation.

VERSATILITY AND MODULARITY
The use of filters with increasing efficiency and
the possibility of implementing pre and post-
filtration systems make Icarus the ideal filter
for all modern mechanical machining, from
the simplest to the most demanding ones.
The three different sizes of Icarus facilitate the
choice for the most appropriate solution for the
customer’s needs, avoiding energy waste for
oversized systems, or insufficient performance
from undersized systems.
MANOMETER
Icarus is equipped with a precise tool to read the
internal filter obstruction state.
ENERGY EFFICIENCY
Using centrifugal fans with high
efficiency grants high performances
for flowrate and pressure, together
with reduced power consumption
and limited energy usage. Icarus
also has very low noise emission.
EASY AND QUICK MAINTENANCE
Access to filtering section is very easy and
quick, you don’t need to unscrew or dismantle
any part. Just open the two locks on the door
and access to the filters, which can be extracted
easily and changed in a few minutes.
GREEN
Losma has always paid many attentions to
eco-sustainability of its products and to the
eco-friendly life of its spare parts. That’s why
an eco-compatible patented BIO FILTER was
developed, made only of natural fibres it can be
used as pre-filter replacing the synthetic filters.
Darwin series is a range of centrifugal filters for
cleaning air containing oil mists, micro-mists
and smokes produced when using coolants
(emulsion or neat oil).
It can be used with a majority of machine tools
for all machining processes.
It is available in 4 sizes with three different,
interchangeable filtration technologies.
Throughputs available are from 600 to 3.000

Air filters
Working principles
Polluted air is drawn into the system (A) thanks
to the depression generated from the rotation
of the centrifuge (B), which gives the air a
swirling movement.
Air passes through the special expanded
polyurethane foam inserts positioned in the
centrifuge (only in mono and double version)
and then into a net. The combination of all
these elements facilitates the re-coalescing of
oil particles - including the finer ones.
Air crosses a further static filtration layer (C)
before being re-introduced into the working
environment (D). The re-condensed liquid
is eliminated through the drainage tube in
constant positive pressure (E).
Darwin series grants a filtration efficiency of
over 95%, also for pollutant particles below one
micron; this efficiency rate can be increased to
99,97% with the use of an absolute post-filter
(HEPA FILTER) according to EN 1822 norms.

Darwin series uses a double filtration combination:
dynamic (given from centrifuge rotation) and
static (with integrated post-filtration system) to
grant high performances.
TWO-STAGE FILTRATION
CONDENSATION AND DRAINAGE
Compared to the most common static air filtration
systems, Darwin series grants incomparable
capacity of re-condensation and drainage;
overpressure inside the filter is used to continuously
discharge coolant which may then be collected
and recycled.
VERSATILITY AND MODULARITY
Darwin series, unique in its category, offers 12
different combinations of filtration technologies
and corresponding aspiration power, facilitating the
choice of a suitable solution for all requirements,
so avoiding energy waste caused by over-sized
systems or, on the other hand, inefficiency caused
by under-sized systems.
32
Air filters
All Darwin systems can be mounted either
horizontally or vertically thanks to an exclusive
cradle, which allows the filter to rotate on its
axis and also allows installation in very small
spaces.
EASY INSTALLATION
QUICK AND EASY MAINTENANCE
Access to the filtering section is very easy and
immediate and does not require unscrewing or
disassembly of any parts. Simply open the cover
which is shut with pressure hooks to access the
filters. They can be extracted and changed very
easily and quickly.

Working principles
Contaminated coolant is piped into the
trough (A) and distributed on the filtration
fabric (B), retaining pollutant particles and
allowing the cleaned coolant to pass.
The fabric collects pollutant particles until
it is full and the coolant cannot cross it
anymore. The coolant rises its level touching
a float, which actions the proximity sensor
controlling the fabric movement and the

HIGH EFFICIENCY AND LOW CONSUMPTION
This system with inclined bed secures to Extra
and Extra High version a maximum level of
hydrostatic flow, which arises the medium
filtration level and at the same time reduces the
filtration tissue consumption.
VERSATILITY
Filtration systems of Extra series are supplied
with a rewinding system.
HYDRAULIC GUARD
(Only for Extra High) a double system of spill
door, positioned on the two sides of the frame
avoids any overflow phenomena caused by a
wrong working of the dragging system.
PROXIMITY
The use of proximity sensors for the control of
tissue movement, instead of the push-piece
spring, allows a precise movement avoiding any
tissue waste.

Working principles
Mud Discharge
Dredging system (C)
Drum + Filter fabric (A)
Discharge opening (B)
The Spring working principle is divided in three
main steps:
The metallic filter net covering the drum is
clean (A). The dirty coolant passes through
it depositing the pollutant particles and goes
through the discharge opening (B). From here
the clean coolant falls into the collection tank
positioned below, from where pumps will
transfer it back to the machine tool. During
this phase the drum does not rotate and the
dredging system is stationary. The polluting
particles deposited on the filter net forms the
actual filtering layer which can also reach a
thickness of 10-15 mm.
As the filter net gradually gets dirty, the liquid
level increases. The dirty coolant continues
to deposit pollutant particles onto the drum
surface, while the drum and dredging system
(C) are still. The filtration level improves due to
the thickness of the mud deposited on the filter
net.
Coolant cannot pass through the filter net any
longer - filter net clogging cycle is complete.
This phase is when the best filtration level is
reached. The longer the filter operates under
these conditions, the better the average
filtration will be. When the coolant reaches the
maximum internal level allowed, a self-cleaning
cycle is started automatically (see box page
4). At the end of this phase the coolant level
descends and the filtration cycle begins again.

Plus
It’s an automatic cleaning system of the metallic
net, used for coolant filtration. Inside the filtration
system there is a sensor, which makes the drum
rotate when the maximum level of clogging
of the net is reached. During the rotation the
dredge system scrapes away deposited muds
from the net, transporting them outside the
filter. Meanwhile, a countercurrent jets system
washes the metallic net, removing even the
tiniest residuals.
AUTOCLEAN SYSTEM
DREDGING SYSTEM
It is used for discharging filtered and decanted
swarf; the system is also available in magnetic
version for ferromagnetic residuals.
PERMANENT FILTERING MATERIALS
Spring system uses metallic filter net which is
cleaned thanks to a self-cleaning system. In
this way consumable material is not used, thus
reducing costs for maintenance and industrial
waste disposal.

it depositing the pollutant particles and goes
through the discharge opening (B). From here
the clean coolant falls into the collection tank
welded in one piece with the filter, from where
pumps will transfer it back to the machine
tool. During this phase the drum does not
rotate and the dredging system is stationary.
The polluting particles deposited on the filter
net forms the actual filtering layer which can
also reach a thickness of 10-15 mm.
As the filter net gradually gets dirty, the liquid
level increases. The dirty coolant continues
to deposit pollutant particles onto the drum
surface, while the drum and dredging system
(C) are still. The filtration level improves due
to the thickness of the mud deposited on the
filter net.
Coolant cannot pass through the filter net any
longer - filter net clogging cycle is complete.
This phase is when the best filtration level
is reached. The longer the filter operates
under these conditions, the better the
average filtration will be. When the coolant
reaches the maximum internal level allowed,
a self-cleaning cycle is started automatically
(see box page 8) and the drum rotates.
At the end of this phase the coolant level
descends and the filtration cycle begins again.

It’s an automatic cleaning system of the metallic
net, used for coolant filtration. Inside the filtration
system there is a sensor, which makes the drum
rotate when the maximum level of clogging of the
net is reached. During the rotation the dredge
system scrapes away deposited muds from the
net, transporting them outside the filter. Meanwhile,
a countercurrent jets system washes the metallic
net, removing even the finest residuals.
AUTOCLEAN SYSTEM
DREDGING SYSTEM
It is used for discharging filtered and decanted
swarf; the system is also available in magnetic
version for ferromagnetic residuals.
NO DEPOSIT IN TANK
Spring Compact processes the coolant quantity
required by every single machine tool in real
time, eliminating mud deposits inside the tank.
PERMANENT FILTERING MATERIALS
Spring Compact uses metallic filter net which
is cleaned thanks to a self-cleaning system. In
this way consumable material is not used, thus
reducing costs for maintenance and industrial
waste disposal.

Liquid filters
Optional
Used to reduce the volume
of mud intended for disposal
and for reducing the liquid
contained therein.
The obtainable compacting
level can change on the basis
of mud, liquid used and many
other factors such as cycle
timing. The reduction in volume
and of humidity is obtained
through pressing with static
load. The volume efficiency
reduction is from 40% to 20%
and for liquid residual from
30% to 10%.

Working principles
Contaminated coolant passes through the
group of rotating magnetic discs (A), where
magnetic particles are captured.
A scraping blade (B) removes the metallic
particles from the rotating group, conveying
them to the sludge chute (C) which collects
1

the waste into a tank.
Clean oil is collected into a tank (D) and
pumped back to the machine tool thanks
to a dedicated pump, or is collected for a
further process of fine filtration.

Skim
Skim is an eliminator of superficial oil, suitable to
be used on every kind of basin or tank, thanks to
its shape and building materials.
Skim is available in two versions: disc (Skim D) or
belt (Skim N).
This last version is suitable in situations of reduced
space and when the tank is not at full capacity.
Skim removes from the coolant surface the veil of
light products, which do not mix with water and
create a barrier and prevents air from entering into
contact with the emulsion allowing the formation
of anaerobic flora bacteria.
Thus the use of Skim preserves the quality of
coolants and eliminates unpleasant odors.
