Product overview
Oil Mist Collectors
Coolant Filters
Air range
• Centrifugal filters: a centrifuge
condenses mist turning
it into liquid. The Darwin family uses this technology.
• Static filters: air is purified through 4 filtration stages.
Newton and Icarus use this system.
• Electrostatic filters: oil particles are positively charged
and the the attraction and repulsion principle of the
electrostatic charge is exploited to eliminate them.
Icarus E and Newton E use this technology.
• Filters for dry dust: pneumatic, self-cleaning cartridge
system; eliminates dust accumulated on the filters and
collects it in an apposite container. Newton D uses this
system
• Modular filters: pre and post modular filters created
to resolve specific pollution problems. Guard and
Clipper belong to this line.
Why Filter?
No filtration
With filtration:
of
• Coolants may be reutilized in the
machine tool
• Higher housekeeping costs
for
cleaning
of
the
workplace
• Surroundings remain clean and costs
are reduced
• More
consumption
coolants = higher costs
• Risk of malfunction
electrical system
of
• Higher risk of accidents and
fire - eg. slippery floor, oil
stained tubing
• Workers’ health risks (es.
allergies, dermatitis, etc.)
• Reduction in risk of malfunction
caused by volatile substances
• Reduction in risk of accidents and fire
thanks to cleaner machines and
surroundings

Centrifugal filters
Darwin
• Type of system: centrifugal air filter for mists and vapours
from soluble or neat oil, ideal also in the presence of solid
dusts. Available also in stainless steel for oil mist and micromist with strong water vapor concentration or particularly
corrosive or salty oils.
• Processes: sharpeners, grinders, metal machining. The
stainless steel version is also suitable for industrial washing
machines and food industry processing.
• Throughput: from 600 to 3.300 m3/h
• Pre/post filters: Guard, Clipper, Clipper P, Microfilter and
Synthesis.
• How does it work?
Models
• Darwin Cyclone Turbine (T): These units are
designed to eliminate soluble oil mists, with
considerable quantity of solid dusts. Ideal for
processes with large quantities of solid dusts; the
deflector improves pre-filtration.
•Darwin Mono centrifuge (M): designed to
eliminate neat and soluble oil mists. Two filtration
stages (1 static and 1 dynamic) a very high degree
of efficiency is guaranteed.
• Darwin Double centrifuge (D): represent the
highest filtration level available on the market.
Designed to eliminate fine-mists and vapours
from neat and soluble oil. The double centrifugal
action and the 3 filtration stages (2 dynamic and 1
static).

Larger and Centralized Systems
Newton and Newton E
• Application: filtration group for purification of air in
work places; suitable for large machine tools or
centralized systems. Dry systems as well.
• Machining: lathing, machining centre, mechanical
machining with cutting oil, grinding, gear cutting
machine, milling machine and thread-cutting machine.
• Main features: available in static and electrostatic
version, with high pressure and low pressure
ventilators; modular structure, units can be connected
with each other to create large centralised systems.
• Accessories: post-filtration with absolute HEPA filter,
available with GREEN filter.

Application examples
Liquid range
• Fabric filters: TNT fabric filter is used to separate
liquid from particles. DTE, Decom and Extra belong
to this family.
• Gravity filters: pollutants deposit on the filtration
fabric, when a maximum level is reached the height
of the liquid starts a new filtration process. The
Master family uses this technology.
• Magnetic separator: Magnetic discs able to
eliminate magnetic particles: Demag, Magneto and
Rotomag.
•Self-cleaning filters: no use of consumable filter
media, when the filtration medium is obstructed
with pollutant, a self-cleaning process is started.
Spring and X26 belong to this family.

Why filter
No filtration
With filtration:
• Reduction in machining precision
and machining is undertaken with
polluted coolant.
• More efficient
defective parts.
• Reduction in tool and pump life.
• Less running expenses
machining life.
• Major consumption of coolant and
higher disposal costs.
• Savings in disposal costs and coolant
acquisition costs; filtered coolant is
recycled.
• Higher maintenance intervention
and longer machine stopping times.
• Less machine stopping time and longer
maintenance intervals.

How does it work
• Type of system: system using fabric filter, suitable for fine metal machining processes
producing both magnetic and non magnetic particulate using soluble oil or neat oil.
Filtration level is determined by the choice of filter fabric. Available also in stainless steel for
water or particularly corrosive or saline liquids. Modular magnetic filtration options.
• Processes: suitable for all machine tools for chip removal.
• Flow rates: from 12 to 100 gal/min emulsion and from 8 to 50 l/min neat oil.
• Accessories: Skim, chip conveyor and chiller.
22
Working process
The coolant falls into the distribution trough and from here goes on the filter cloth which is positioned on a belt. The solid pollutant
particles (dust and swarf) are retained by the cloth while the filtered oil is collected into the tank and pumped back to the machine
tool. When the part of the cloth lying on the belt is full of pollutant (and has lost its filtering capacity) an automatic system advances
the used cloth towards the sludge collection tray at the end of the tank. New cloth passes under the cloth-stretcher tube and goes on
the belt ready to filter the coolant.

Coolant Filtration Systems
Type of system: self-cleaning drum filter complete with a
fixed, metallic filtering membrane. The range is composed
by three systems: Spring, Spring V and Spring Compact.
• Processes: machining centers, deep drilling, transfer,
grinding, lathing, processes with high pressure special tools
and combined machines.
• Flow rate: from 12 to 500 gal/min for emulsion depending
on filtration level.
• Accessories: Skim, sludge compactor, chip conveyor and
chiller.
26
Models
• Spring: self-cleaning drum filter, for soluble or
neat oil coolants, with permanent filtering net.
Filtration level varies from 15 to 100 micron.
• Spring Compact: self-cleaning drum filter
designed according to customer requirements;
filtration level varies from 15 to 100 micron.
Dimension and flow rate may vary. Operates
without accumulation of clean coolant as
filtration takes place in real time in required
quantites and is sent directly to the machine
tool.
• Spring V: self-cleaning, vacuum drum filter,
suitable for processes with neat oil.
27
Working process
Spring / Spring Compact
Phase 1: the dirty liquid deposits polluted parts on the drum’s
surface. The clean liquid passes inside, falls through the opening
and into the tank below. The polluted material deposited on the
filter net forms a filtering layer with a thickness of even 10-15
mm.
Phase 2: the filter net gets dirty, the liquid level increases and
the dirty liquid continues to deposit the polluting parts on the
drum’s surface. The filtration degree improves due to the
thickness of the mud deposited on the filter net.
Phase 3: The filter net stops the liquid from passing through, the
maximum permitted level is reached as well as the best possible
filtration degree. The washing cycle begins with the intervention
of jets that wash the net counter- current. The drum rotates and
the dragging system starts, scraping the deposited mud. The
level lowers and phase 2 is repeated.

X26
• Type of system: high efficiency, self-cleanin cartridge filter
which does not require consumable filter media.
Processes: suitable for fine and ultra-fine filtration of low
viscosity processing liquids, specifically for processes requiring a
perfect control of the liquid’s state of contamination.
• Flow rate: completely customisable according to customer
requiements.
• Accessories: Chillers.
30
Working process
Dirty coolant under pressure is introduced into the
filter through the dirty chamber and from there into
the filter cartridges. Filtration process takes place from
the inside towards the outside, the filtered coolant
exits clean into the upper chamber and from there, by
means of residual pressure, is sent back to the working
process. The completely automatic cleaning does not
interrupt the filtration process. Solid filtered and
separated particles are removed by back-flush during
the cleaning cycle. Residual sludge is removed by
means of a discharge valve at the bottom of the filter.
