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.

4.3. Installation
To mount the air filter, as well as the material supplied in the assembly kit, the following components are also necessary:
•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.
•Insert the other end of the 2 safety tie-rods on the threaded pin of the anti-vibration joints.
•Mount the washers and nuts on the 4 threaded pins of the anti-vibrating joints.
•Tighten firmly.

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”.
