Sweet! I did not know this.. I even had to look up what a blast furnace was hahaha. I knew this was used in some kind of industrial process but not sure what exactly. Thanks for the positive vibes.

Thank you!

Yea evaporation can be a problem depending on shop environment. I simply have my garage so it is generally cold and gets equalized with outside air since i open and close the door a lot. May not work for people that have more hotter climates or enclosed shops

That is brilliant! Thanks for the tips I'll try them next time.

Actually what you suggest is a better design and what I would do the next time as current design has a small screen in the tube connecting cyclone to motor. There are two lame reasons why I did it this way, one was because it slightly simplifies wet scrubber as i dont need a sealed container with inlet and outlet ports. (I didn't have any lids on the plastic bins to add a port where motor could suck air out of wet scrubber) Second reason would be the marginal sound dampening wet scrubber provides. Provided the wet scrubber was shortened a hair to be able to fit into the water bin and it had a lid, it is really easy to change the order of the stages using pvc pipe, you could even have wet scrubber be first stage if you want to suck up mostly liquids for a wet spill.My next design i wan...

There should be a link just under step 1, link is https://cdn.instructables.com/ORIG/FOP/ZJ99/JC0U65LA/FOPZJ99JC0U65LA.skp

Ahh like a voltage follower circuit? Thanks I will try that out. Didn't quite understand when you mention two steps mode, do you mean two speeds?

That would be great! Thanks for the positive energy :)

Hi, For this I actually bought a case of 20 empty CD cases for experimentation. They were about a dollar a piece. Before that I collected some from friends.

hahaha thanks! ... and an electric motor too :) Actually people do build centrifugal fans out of them but they are in the form of "Tesla turbine" which are boundary effect blowers -not enough pressure for a vaccum as they are low pressure / high efficiency.

Thanks for comment :) I've been hoarding these containers for far too long - I had to do something with them. I'll post another instructables when I get the bugs worked out of the next version.

Thank you! I aim to please :) The next iteration will be even cooler! :)

No problemo let me know if you have any questions. I've onto the next iteration that has secondary water filtration but it isn't ready for prime time yet. Best,Jimmy
