I mentioned in another thread my impression that I was losing suck in my Axminster 2200 extractor. I have a fine filter from RB Industrial fitted in place of the standard bag and my usual practice is to whack it a few times each time I change bags...just to loosen up and let fall any fine dust from it into the bag. I even went as far as to use my SDS hammer drill beating against a piece of wood against the side of the filter.
Last weekend I bit the bullet and donning a respirator removed the filter and took it outside. Looking inside I saw it totally covered in fine dust which would explain the loss of suck. I cleaned out about a bucket full of fine dust and now the extractor is breathing easier.
But it does raise a few questions:
1) Maybe there is something about those cyclones after all!
2) Presumably there is a 'life' of these filters?
3) I've read somewhere that for the filters to 'work' then they need a fine coating of dust inside..but wonder if this is a 'woodworking' myth?
4) The Axminster fine filter has a paddle which in hindsight seems like a good idea.
5) I wish I'd 'calibrated' the suck when I first bought it as a reference point.
Any thoughts?
As background, I rarely use MDF or man-made boards - use primarily oak.
