however...
would you prefer a particle separator that meets or exceeds the performance of the current barrier filters, yet does not require periodic maintenance & cleaning? this way you can operate continuously with little or no risk (doesn't load up), including in snow & ice conditions. The current 206/407 separator is a dated design, rooted from the '70's. The latest generation separators, which are extremely efficient, can be seen in Eurocopter & Agusta platforms.
