Thread: Downdraft table

That's a really great job, Leigh and I too plead guilty to divisions for over a dozen different grits and then using just a couple! . Having worked in the battery industry for a few years I am a great fan of downdraft tables or benches. Overhead extraction systems might be easier to install but the downside (pun intended) is that dust, fumes or whatever gets drawn up straight past your face and that's not good (especially if it's lead dust from battery plates ).

I am still not convinced as nice as that looks, fine dust floats as soon as it is released and to capture it takes a LOT of air and I don't know of a hobby DE that could do that.

Hobby DE - jeez, tough crowd!

Ok - technically not dust free.

The sun shines through the window in the morning and highlights dust pretty well. When I dust off a sanded job with a brush, a cloud of dust is created and I can see it being sucked down into the bench top. I actually didn’t expect it to work as well as it does.

I also use it together with a vacuum when machine sanding.

So agreed, not perfect, but much, much better than nothing and I highly recommend it.

Nice work.
First time I’ve heard a Clearvue referred to as a hobby DE

I introduced CV to Oz and it is as hobby DC and was never intended to be anything else. A better description might be a DE for a hobbyist and CV have only recently introduced a cyclone more suited to industrial use which is not available in Australia as they won't allow it to be exported. That the original cyclone design gets used in a few industrial situations speaks loads for its capabilities.

Yes Chris, I think most are aware of your affiliation with Clearvue.
The problem is it’s been hammered on this site, when there are any questions re DEs, as the be all and end all of DEs. They have even been recommended, and fitted, in Mens Sheds which would be considered a step above hobby use one would think.
So based on their recommendation and reputation they certainly would be considered several steps above the usual hobby 2hp and 3 hp units wouldn’t you think?
So based on your appraisal of them I will now consider them as just a hobby unit along with the usual suspects.

CV are in a niche of their own, above the usual generic DE and below what a true industrial one is. I have tried to get Clearvue to consider making a 17" impeller version for Australia aimed at Men's Sheds in particular but that went nowhere. A 17" impeller would make it suitable for light industrial as well but they don't get the unique requirements we have. This is going a bit off topic but I am surprised at the number of MS's that do not have ducted systems at all which is most of them. Now back to DD tables, sorry for the off topic.
