2. Description
2.1. Function and field of application
•The air filter DARWIN D (double centrifuge) is suitable for all machine tools for metal production (other than
grinders and sharpeners). It specifically eliminates neat or soluble oil mist and vapours, also in the presence of small
amounts of solid particles.
•The air filter DARWIN M (monocentrifuge) is suitable for all machine tools for metal production (other than
grinders and sharpeners) It specifically eliminates neat or soluble oil mist, also in presence of small amounts of solid
particles.
•The air filter DARWIN T (turbine) is suitable for grinders and sharpeners. It eliminates soluble oil mist, also in
presence of relevant amounts of solid, metallic and abrasive particles.
Note
•The mist of soluble or neat oil (air + liquid pollutant with particle dimensions between 0.8 and 10
µ m*) are
generated by the action (purely mechanical) of rotating parts such as tools, pieces being machined, etc.
•The vapours from neat or soluble oil (air + liquid pollutant with particle dimensions between 0.5 and 0.8
µ m*)
are generated by the thermal actions (friction heat between piece and tools, electrical resistance heat as that
generated during hardening treatments) and by pressure (forced atomisation of coolants, high pressure forced
lubrication)
*
(The declared values are purely indicative)
Warning! Danger!
The air filters are not suitable for dry dust. They do not absorb this kind of pollutant which, after suction is re-
circulated in the air. In case of production generating dry dust, the air filter is not effective and must be
disconnected.

•Flexible suction hose TFM of adequate length + 2 hose clamps
•Flexible suction hose diam. 25 mm, TFD of adequate length + 1 hose clamp
•In case the machine is enclosed, PRT pipe connection plate, nuts and bolts.
•Find a suitable position for the installation of the air filter (on the machine tool or immediate close to it) and decide the
position of the air filter (vertical or horizontal) according to the available space or the shape of the machine cabin.
•Drill the necessary holes to position the air filter on the machine cabin, as illustrated in the drilling schemes (enclosure
“Drilling schemes”).
•If the PRT pipe connection plate is necessary, drill the 4 holes, diam. 5, on the machine cabin, as illustrated in enclosure
no.3 “Drilling schemes”.
Warning!
•In order to avoid dangerous filtering of solid dust and coolant liquids, it is advisable to keep the suction hose
away from areas with a considerable presence of solid dust and sprays of coolant liquids.
•To avoid pressure drop, it is advisable to use a suction pipe with a maximum length of 2 metres. Furthermore, to
prevent liquid stagnation inside the flexible pipes, avoid depressions when positioning it.
•Insert an eyebolt of one of the supplied safety tie-rods, on the threaded pins of the anti-vibration joints.
•Assemble the 4 anti-vibration joints on the previously drilled support surface, positioning the 2 joints - complete with
safety tie-rods - in a diagonal position, as indicated in drawing 3.
- If you have drilled clearance holes, fix the anti-vibration joints to the support surface by means of the washer and nuts
supplied.
- If you have drilled threaded holes, screw the anti-vibration joints directly on the support surface.
•If foreseen, fix the PRT pipe connection plate to the machine tool cabin
•Lift the air filter by means of the special eyebolt and position it on the anti-vibration joints.

Important!
The packaged equipment is always shipped with the screws loosened. This ensures that the Ø6mm screw,
which restricts the rotation, does not get damaged during transportation or when the product is being extracted
from the packaging.
Once the product has been extracted from the packaging, it is possible to choose the position, as shown in the
illustration.
Fig.A Fig.B Fig.C
The three illustrations show the possible positions taken on by the product: horizontal or vertical.
In fig. C, provided for the assembly of the Darwin with pre-filters and post-filters, the body of the aspirator must
be released from its support (cradle) and moved on holes prepared in the underlying transverse beam (except
for the Darwin 600, in which there is only one transverse beam).
In this position, the aspirator can only be used in a horizontal position.
4.3.1. Determination of the functioning position: Horizontal or Vertical
In order to rotate the equipment, having the N°2 Ø8 screws as a fulcrum, “screw 1” must be slightly loosened to
enable movement, after which “screw 2” must be unscrewed, making it exit from the seat made in the body of
the aspirator.
Once the required rotation has been carried out (either Vertical or Horizontal), re-screw “screw 2”, making it
return back to the appropriate seat and tighten completely “screw 1”.

4.4. Electrical connections
It is advisable to keep the air filter in operation during the entire work shift, in order to avoid frequent starting and
stopping. In this way the air filter ensures the best performance and is not subject to unnecessary and
detrimental thermal and mechanical stress.
Warning! Danger!
Before making the electrical connection of the air filter cut off the power supply (main switch). Exclusively qualified
electricians must carry out all operations.
A power supply automatic cut off must be used as the protection system from indirect contact (refer to the norm EN
60204-1 and 1998-04; For this reason the oilmist filter must be equipped with an equipotent protection circuit that
must include a protection switch to avoid problems in case of power supply failure as. Refer to the requirements
indicated in 413.1 of the publication IEC 60364-4-41
The DARWIN air filter in its STANDARD configuration is supplied with power cable and multi-polar plug and socket. The last
one simplifies the disassembling operations of the rear filter during regular maintenance operations.
As accessory a Stop/running switch is available on request.
It is advisable to protect the electric motor of the air filter by using a magneto thermal switch.
Note!
For Darwin 3000 with 60 Hz motor, the protection is:
a) a thermal switch for 3 ÷ 12 A with cycle time 20 seconds
b) a magnetic switch for 8 A running current.
•Check that the connection voltage indicated on the test sheet on the unit corresponds to that of the power supply
network.
•Read the motor plate information to select the correct connection materials (cable section, fuses, magneto thermal
switch, etc.)
•Make the electrical connection from the electric switchboard of the machine tool to the DARWIN power cables (see
drawing 6) inserting the multi-polar socket/plug. This will speed up and facilitate future maintenance operations.
•Assemble the chosen motor protection device inside the machine tool switch-board (magneto thermal switch for starting
the motors).
•Electrical connections must be carried out as illustrated in drawing 6 and, in any case, in compliance with applicable
norms in order to carry out a professional installation.
•Start up the air filter, following the applicable safety regulations.
•Check through the suction mouth that the direction of rotation of the air filter rotor corresponds to that indicated by the
arrow-label (the rotor must rotate in a clockwise direction).
•Should the direction of rotation be contrary to that indicated in the arrow, invert the connection between the two phases.
•Check that the motor-protector switch calibration complies with the power absorption characteristics of the motor
indicated on the motor plate.

6.3.3. Filter cleaning
Note
The used filters and the liquids used for washing are special waste. Take this waste to authorised collection and disposal
centres.
It is advisable to regularly replace the synthetic filters as indicated in the Programmed Maintenance Table (item 6.3.1). If the
filters structure is fully integral, it is possible to regenerate them (instead of replacing them) by putting them into a solution of
industrial detergent and water for about 12 hours. Before re-assembling the filters, dry them with a jet of compressed air or
leave them to dry naturally.
Danger!
The used filters and the seals are special waste. While waiting for disposal, they must be kept in hermetically
closed containers, which must be located far from the working areas.
6.3.4. Internal cleaning
Careful and regular cleaning of all the internal parts (shell, drainage pipe, drainage ring, etc.) ensures high performance and
long life of the air filter.
It is of fundamental importance to periodically check the inside of the centrifuge or the blades of the turbine to
eliminate eventual deposits of metal particles, sludge or other material which could cause loss of balance of the
centrifuge or of the turbine.
Warning
The functioning of the air filter with unbalanced turbine or centrifuge (even if for a short time) could seriously
damage the air filter components.
For the internal cleaning of the air filter and the rotors (either turbine or centrifuge) use a clean brush saturated in a mild
industrial detergent solution. Alternatively standard liquid soaps can be used.
Should the dirt be very resistant, it is advisable to remove the rotor (for rotor dismantling see 6.4) and use the following
alternative cleaning solutions:
-A jet of steam at a temperature of over 100°C.
-An industrial detergent solution in water, soaking the rotor for at least 12 hours.
Allow the centrifugal device to dry in the open air or dry with a jet of compressed air.
6.4. Special maintenance
Danger!
The special maintenance operations are to be undertaken by qualified technicians only. Skilled electricians should
carry out work on the electrical parts.
Before beginning the maintenance procedure:
•Position the general switch of the machine tool to "OFF" and lock it.
•Wait at least 3 minutes in order to allow the rotor to come to a complete stop.
•Disconnect the control device from the plug and socket of the air filter.
•Place on the machine tool the apposite sign "Maintenance in progress".
•Wear goggles and protective clothing (gloves, safety shoes, etc.).
6.4.1. General disassembly and reassembly
Warning! Danger!
During the re-assembly and before starting up the air filter again make sure that all the components are correctly
secured and mounted.
In particular, check:
•The correct tightening of the screws connecting the motor to the relative support.
•The correct tightening of the screw connecting the rotor to the motor shaft.
EN

35
•The correct assembly of filters and seals.
•The correct assembly of electrical connections.
•That there are no objects or tools inside the air filter.
•Check through the suction mouth that the direction of rotation of the air filter rotor corresponds to that
indicated by the arrow-label (the rotor must rotate in a clockwise direction).
•Reassemble and secure the front lid inserting the two safety pins into the hooks.
•Disconnect the air filter from the machine tool. To remove and lift it up use the apposite eyebolt. Place the air filter
on a workbench.
•Remove the two safety pins mounted on the hooks of the front lid.
•Release and remove the front lid.
•Release and remove the rear lid.
•Unscrew the blocking screws of the rotor.
•Using the special extractor remove the rotor from the motor shaft.
•Loosen the 4 screws, which fix the motor to the support and remove the motor.
•Unscrew the 4 nuts and the eyebolt and remove the 5 screws securing the support to the air filter shell.
•Extract the support from the shell.
To remount the air filter undertake the dismantling operations in reverse order using new safety pins, seals, washer and self-
blocking nuts.
It is also advisable to block the threads of the bolts connecting the motor support to the shell using thread-blocking
substance "Arexons sistem forte 52A70" or an equivalent product.
6.4.2. Motor maintenance
At regular intervals and, in any case, during normal maintenance of other components of the air filter, it is advisable to
regularly check that the motor shaft rotates freely and does not produce anomalous sounds.
Anomalous noises coming from the electric motor are usually an indication that the ball bearings are worn. In this case
replace them following the instructions provided below.
•
•On reassembly of the bearings and the sealing ring, avoid using inadequate tools which may damage these
components.
•On reassembling the motor install all components in their original and correct position.
•At the end of reassembly check that the shaft rotates freely and that the new bearings installed do not make any
noise.
Note
The dismantling operations indicated may vary according to the type of electric motor mounted on the air filter. The
instructions provided below is only a general indication of the recommended dismantling order of the electric motor
components.
•Dismantle the electric motor from the air filter, see paragraph 6.4.1
•Remove the tab from the electric motor shaft.
•Remove the fixture screws of the fan-cover and the cooling fan
•Loosen the 4 or 8 closure screws of the electric motor cover.
•If the motor has a rear or front bearing, unscrew the two blocking screws.
•With the aid of a plastic mallet, remove the front and rear covering. Pay particular attention to the positioning of the
pre-load washers mounted in the coverings.
•Remove the electric motor shaft.
•Dismantle the bearings using a special extractor.
•Dismantle the oil-protection bearings using a special extractor
For reassembly undertake the operations as indicated above in reverse order replacing all worn parts.

6.5. Structural checks
•Each year:
Check that the nuts of the anti-vibration joints are firmly tightened.
•Every 2 years:
Check the condition of the safety tie rods.
Check the good condition of the Darwin shell.
•Every 4 years:
Replace the anti-vibration joints.
7. Disposal
Danger!
Solely adequately trained and equipped personnel must carry out the machine disconnection and disposal
operations.
The used filters, the internal parts in rubber and all components with oil residuals are special waste to be disposed through
authorized organizations.
To allow for the reutilization of the raw materials it is also advisable to separate:
•The metal parts.
•The electric motor.
•The rubber parts.
•The synthetic material parts.
Note
LOSMA S.P.A. does not assume any responsibility for damage to persons or things resulting from reutilization of individual
parts of the machine for operations or in assembly condition others than the original ones for which the machine was
designed.
