There was a magnified pic of the high side filter posted on the other forum recently but the thread was deleted due to turning into war zone. A pity that good photo went out with the garbage.
It's why many of us here are no longer over there. I have also dropped out of several Facebook groups due to a high proportion of aggressive ****holes. Luckily there is still this forum and there are still a few C10/C14 groups on FB where people behave like civilised human beings, or where they get policed heavily so that the ****holes never get a chance to start anything.
I assume that this "high-pressure" filter is a wire mesh rather than a fabric filter like the main one, and it can just be blown clean with a blast of air the other way?
I've looked for pics online and cannot find any decent ones for it.
