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.

8 Why Filter? With filtration: No filtration More consumption
of coolants = higher costs Higher housekeeping costs for cleaning
of the workplace Risk of malfunction of electrical system Higher
risk of accidents and fire - eg. slippery floor, oil stained tubing
Workers health risks (es. allergies, dermatitis, etc.) Coolants may
be reutilized in the machine tool Surroundings remain clean and
costs are reduced Reduction in risk of malfunction caused by
volatile substances Reduction in risk of accidents and fire thanks
to cleaner machines and surroundings Healthier and more motivating
environment for workers, less absences and more productivity

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).

19 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.
Slide 20
20 Why filter With filtration: More efficient machining and
less defective parts. Less running expenses and longer machining
life. Savings in disposal costs and coolant acquisition costs;
filtered coolant is recycled. Less machine stopping time and longer
maintenance intervals. No filtration Reduction in machining
precision and machining is undertaken with polluted coolant.
Reduction in tool and pump life. Major consumption of coolant and
higher disposal costs. Higher maintenance intervention and longer
machine stopping times.

Slide 22
22 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.
Slide 23
23 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.

26 Large or Centralized 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.
Slide 27
27 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.
Slide 28
28 Working process Spring / Spring Compact Phase 1: the dirty
liquid deposits polluted parts on the drums 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 drums
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.

30 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 liquids state of contamination. Flow rate:
completely customisable according to customer requiements.
Accessories: Chillers.
Slide 31
31 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.
