DARWIN D3000D oil mist collector
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, interchangeable filtration technologies.
Throughputs available are from 600 to 3.000 m3/h, with different combination for increasing filtration efficiency, up to 99,97%.
Working principles
1. Polluted air is drawn into the system (A) thanks to the depression generated from the rotation
of the centrifuge (B), which gives the air a swirling movement.
2. 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.
3. Air crosses a further static filtration layer (C) before being re-introduced into the working environment (D). The re-condensed liquid is eliminated through the drainage tube in constant positive pressure (E).
4. 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.
Turbine
Suitable for surface machining (sharpeners, grinders, honing,
lapping and similar finishing processes) also in the presence of heavy particulates.
Mono centrifuge
Suitable for all machining processes (emulsion or neat oil).
Double centrifuge
Suitable for all machining processes (emulsion or neat oil) in particular for heavy machining conditions such as use of high pressure which generates micro-mists and vapours.
TWO-STAGE FILTRATION
Darwin series uses a double filtration combination: dynamic (given from centrifuge rotation) and static (with integrated post-filtration system) to grant high performances.
CONDENSATION AND DRAINAGE
Compared to the most common static air filtration systems, Darwin series grants incomparable capacity of re-condensation and drainage; overpressure inside the filter is used to continuously discharge coolant which may then be collected and recycled.
EASY INSTALLATION
All Darwin systems can be mounted either horizontally or vertically thanks to an exclusive cradle, which allows the filter to rotate on its axis and also allows installation in very small spaces.
QUICK AND EASY MAINTENANCE
Access to the filtering section is very easy and immediate and does not require unscrewing or disassembly of any parts. Simply open the cover which is shut with pressure hooks to access the filters. They can be extracted and changed very easily and quickly.
