Particla Separators
 

Could someone please give me some information on 'Particle Separators, Exactly how they work and where to contact the manufactures?
Many thanks

You'll have to be a bit more specific - rotary or fixed wing ? Aircraft type and system ?

What I am researching is the replacement of the usual paper air cleaner used for motor vehicle engines with a particle separator type that is used on rotary wing engines. JR206/Eurocopter designs come to mind. The present helicopter does not have a particle separator so I have no physical bits to play with.

The particle seaparators I'm familliar with on Bk117 and the Bell 212/412 have no filter element at all. The Bk has tiny little vortex generators in a panel, and has an extractor fan to suck out any sand or tiny particles that could get through the panel. The Bell style is just a straight duct with a door on it and when the separator is working, the door is open and any particle just keeps going through the duct by momentum, and the air is allowed to suck in from the bottom of the duct. The compressor inlet on both machines also have a wire screen fitted to collect any debris that may make it through.

You mean like the one's fitted in those bright yellow, grey and transparent vacumn cleaners.

Is this the sort of thing you want?

The Engine air filter you speak of is made by the Pall corporation. Their web site is: http://www.pall.com/aerospace/

The 206 Particle Separator uses engine bleed air to expell the heavy particles as they enter the swirl tubes.

If you plan on using this type of filter on a non turbine engine application then you will need a source of high pressure air in order to make the filter operational.
