Thread: Principles of Dust Extraction / Management for a new shed

If John thinks he is biased because he has a ClearVue cyclone i must be mega biased as I liked them so much I became the Aussie distributor.

I bow to BobL's knowledge on all things technical. One day when I get the time I want to make a video of an Australian installation. However do not fear there is plenty of help out there if you need it.

When we talk about exhausting the cyclone outside if we are talking about a clearvue the volume of dust remaining is so small it is almost impossible to see. One issue you must allow for is that if you move large volumes of air you will create noise. In most cases you need to provide some type of soundproofing and muffling arrangement.

I am hoping that in the near future I will be able to supply a muffler as a standard accessory. They are not much used in the States since most woodworkers there want to save on heat loss so they use filters which have a natural muffling effect.

Keep asking questions. I think most forumites love answering questions and sometimes a new viewpoint on an issue causes us to rethink and come up with something useful.

The volume of dust that exhausts from a cyclone is indeed small, but more specifically it's the particle sizes (or volumes) that are exhausted that are so small that makes them impossible to be seen with the human eye. If that same small volume consisted of large particles it might be visible to some people. If a lot of fine dust is being generated (eg sanding) more invisible dust will also be exhausted and if the air outside in the exhausted area is still for an extended period some settling and clumping of the invisible dust may occur and render the dust visible.

It would be interesting to know the actual dust particle distribution of the exhausted air from a Cleavue.

Short of using a nuclear isotope I cannot think of a good way of doing that. Any Ideas BobL?

Does anyone in WA have one that you know of that I could visit?
or
Maybe next time I head east I could take my measuring gear with me - nothing coming up in the near future though.

Bob,

When you head east ... Brisbane is a great spot to visit ... and your room will be ready at my place.

Thanks - you never know when that might happen

Bob, Our mens shed is in the process of installing a Clearvue Max that you could measure. You did a dust test on our old 2hp dusty 12 months ago.

Great - let me know when it is installed. From memory your mens shed has underfloor 4" ducting? If so you won't see that much of an improvement over the 2HP DC.

We are updating all ducting & machinery ports to 6". Also adding extra ducting for equipment that currently isn't ducted.

Sounds great!

Bob,

We have the Clearvue up and running, still need to connect 6" ducting to machines, but you can now test dust levels in the system exhaust.

See this thread BMS Clearvue installation

Contact me by PM to arrange day.

Regards.
