HERBET Abel Dec 31, 2014:

Merci Suzanne

Suzanne Barbeau (asker) Dec 31, 2014:

Yes, I had a look to the link http://www.vibratingscreenmesh.com/product/self-cleaning-scr... which shows in deep details what the colleague Tony M. explained in words and the colleague Herbet Abel translated as "procédé sans colmatage". This is in fact what I decided to use in my translation (already sent to the client now).

HERBET Abel Dec 29, 2014:

Ce sont en général des filtres avec cylindre rotatifs, plus considérés comme des séparateurs que comme des filtres au sens plein du terme usuel.

Suzanne Barbeau (asker) Dec 29, 2014:

I thank your intelligence

Tony M Dec 29, 2014:

No specialist, but... ...I would imagine it means that there are no 'blind' areas of the filter where the holes become clogged (like a sieve in your kitchen!) — because there is this huge force of 500 G meaning everything goes through (or not), but in any event doesn't get stuck and cause 'blind spots'.

Suzanne Barbeau (asker) Dec 29, 2014:

yes, and it would mean ?

Tony M Dec 29, 2014:

I expect you realized... that the sense would be clearer had it been written as 'blind-free process' — i.e. 'a process free from blinds'.
