Product overview Coolant Filters Oil Mist Collectors
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 • 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.) With filtration: • 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 8

Air range 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 micro-mist 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).

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. • How does it work?
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. 19
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. 20

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. 23
Liquid range Self-cleaning filters X26 25
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. 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. 28
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. 31
