DARWIN series is a range of centrifugal filters for cleaning air containing oil mists, micro-mists and smokes produced when using coolants (emulsion or neat oil). It can be used with a majority of machine tools for all machining processes. It is available in 4 sizes with three different filtration interchangeable technologies. Throughputs available are from 600 to 3.000 m3/h, with different combination for increasing filtration efficiency, up to 99,97%.

It's avalaible in the follow setup:


Suitable for all machining processes (emulsion or neat oil).


Suitable for all machining processes (emulsion or neat oil) in particular for those demanding conditions such as the use of high pressure coolant, generating micro-mists and vapor’s.


Suitable for the machining of superficial removal (sharpeners, grinders, honing, lapping and all similar finishing processes) also with the presence of heavy particulates.

Working principles

  • Polluted air is drawn into the system thanks to the depression generated from the rotation of the centrifuge, which gives the air a swirling movement.
  • Air passes through the special expanded polyurethane foam inserts positioned in the centrifuge (only in mono and double version) and then into a net. The combination of all these elements facilitates the re-coalescing of oil particles – including the finer ones.
  • Air crosses a further static filtration layer before being re-introduced into the working environment. The re-condensed liquid is eliminated through the drainage tube in  constant positive pressure.
  • Darwin series grants a filtration efficiency of over 95%, also for pollutant particles below one micron; this efficiency rate can be increased to 99,97% with the use of an absolute post-filter (HEPA FILTER) according to EN 1822 norms.
