Hard to find a bigger sheep wool fan here, from sox to shirts, winter to summer, thats the material l love to wear. Never cold, never hot. I took great care when l was about 12 years old, learning the art of makeing woven sox and clothes for the day my grandgrandmother will not be able to suply me with them. But, l must say, l question wools performance in woodgas filtration.
Yes, as a “hay filter” hay substitute, but not as a “paper” or “cloth” filter style filtration.
A hayfilter plays on the card of vast surface area. Presumeing the soot particles/droplets will sooner or later hit a wet grass blade, glueing to it. And if it doesent hit it?
Since all the effects of wool Steve had destcibed above, yes, wool is a perfect material for a hayfilter media. Drains water the same way it drains sweat.
I have alway been more in to “ziher” (sure) things. Not alowing any particles to pass. But its a hell of a jurney to make it happen, efficiantly and DIY.
My venturi scrubber DID catch all the soot. But like the “bubbling effect” Steve mentioned above on the foam filter, well, its eaven worse in a scrubber.
A scrubber with a final cyclone(s) to drive out the sooty droplets? Maybee… but for now, l think l will stick to fabric/towel filters.
Edit: one more positive thing about a wool “hay” filter media. Once used and saturated with soot, one culd compost it. Wool makes great rich compost.
