    Centrifugal Fan Unit for mists and fumes.

    The Darwin series is a line of centrifugal filters for the purification of air containing oily mists, micro-mists and fumes resulting from the use of coolants (emulsion or neat oil).

    It can be used on all types of machine tools and for all removal operations.

    It is available in 4 sizes with 3 different fully interchangeable filtration technologies. Available flow rates range from 600 to 3,000 m3/h, with various combinations of increasing filtration efficiency, up to an efficiency of 99.97%.

    Patented in the USA and Europe (Italy, France, Germany, Great Britain, Luxembourg, Switzerland, Sweden, Spain).

    Losma guarantees that each filter unit is individually tested through rigorous control procedures. A quality and functional test certificate is issued for each unit.

    • The polluted air is filtered thanks to the depression generated by the rotation of the centrifuge, which imparts a strong swirling movement to the air.
    • This passes through special npolyurethane foam sponges housed inside the centrifuge (only in the single and double versions) and then through a perforated mesh. The combination of all these elements facilitates the re-aggregation of even the finest oil mist particles.
    • Finally, the air passes through a further static filtration stage before being returned to the working environment.
    • The recondensed liquid is easily and efficiently discharged out of the filter unit by means of a drainage pipe with continuous overpressure. 
    • FILTRATION TECHNOLOGIES Darwin is available in 3 versions: turbine, single centrifuge and double centrifuge.
    • TURBINE - Suitable for all surface grinding operations (grinding, sharpening, honing, lapping and all similar finishing operations) even with small amounts of solid particles. 
    • SINGLE CENTRIFUGE - Suitable for all removal operations (emulsion as whole oil).
    • DOUBLE CENTRIFUGE - Suitable for all machining operations (emulsion as whole oil), especially for harsh working conditions such as, for example, the use of high pressure that generates micro-mists and vapours.
    • DUAL FILTRATION SYSTEM
      The Darwin series uses a dual combination of filtration: dynamic (given by the rotation of the centrifuge) and static (with the integrated post-filtration system) to guarantee high performance.
    • VERSATILITY AND MODULARITY
      The unique Darwin series offers 12 different possible combinations of filtration technology and relative suction power, making it easy to choose a solution that always fits your needs without wasting energy on oversized systems or, on the contrary, inefficient on inadequately sized systems.
    • STAINLESS STEEL VERSION
      All models in the Darwin series can be supplied in satin-finished stainless steel for use in those applications where normal painted sheet metal is not suitable.
    • CONDENSATION AND DRAINAGE
      Unlike common static filter systems, the Darwin series guarantees unparalleled recondensation and drainage capacity. In fact, it uses the overpressure generated inside the filter unit to continuously discharge the liquid, which can then be recovered and reused.
    • Guard pre-filter
      Pre-filter for chips and dust, equipped with metal and synthetic filter stages. Useful for maximising filtration efficiency at high outputs of oil mist mixed with metal chips and dust.
    • Clipper post-filter
      Available with filtration F9 at 95 % or H13 at 99.95 % in accordance with EN 1822. Especially suitable in the presence of micro-mists or fumes.
    • X-VIEW
      Filter clogging sensor
      The X-VIEW Sensor is able to detect the progressive clogging state of the Darwin filters, signalling three main operating phases:
      GREEN: Clean Filters;
      YELLOW: Pre clogging;
      RED: Clogging.
      Thanks to an integrated TIMER, the X-VIEW sensor allows to know when 15,000 working hours (i.e. 5 years/8 hours per day) have been achieved, which is the recommended threshold for changing the filter set. The X-VIEW sensor can be positioned on Darwin or in any other part of the machine tool where the operator is more comfortable reading the data.
    • X-View also displays:
      possible upstream obstructions: whether by chip or liquid build-up. X-View is capable of detecting instantaneous or progressive clogging in the inlet pipe or suction grid of the machine tool cabin;
      zero flow alarm. For example, when Darwin is switched off or when the motor is not running or a pipe is disconnected;
      the timer indicates the achievement of 15,000 working hours - the threshold recommended for checking the filters.
