Extraction

So for those of you cleaning/trimming, what do you do for evacuation/dust cleanup/control?

Festool extractor with dust deputy attachment

So like,http://www.festoolproducts.com/Festool-583492-CT-26-HEPA-Dust-Extractor-p/583492.htm?gclid=CLat7tGyu70CFUNo7AodqBUAMQ and,http://www.woodcraft.com/Product/2021015/26325/Oneida-Molded-Dust-Deputy-Kit-With-Two-5-Gallon-Plastic-Buckets.aspx?keyword=brandOneida_and_adwords_labelsTwoStage_and_Cyclones&refcode=10INGOPB&device=c&network=g&matchtype=&gclid=CKTI_6uyu70CFY3m7AodCGUA9w ?

5HP cyclone with 12" ducting, running to 6" drops, reduced to 4" inlets. Can have a couple people trimming/sanding at a time, as we have a few drops.

Looks like this:

Also have a cheap $400 air cleaner to that does a surprisingly good job, better than I thought it would.

Probably will be upgrading to a 10hp cyclone soon. Its like 4000 CFM and would be a nice improvement.

^I’ve been looking at a JET one like the above.

I’m trying to be proactive as opposed to reactive.

If that is the case, get the biggest ducting you can afford. I started with 4" and it wasn’t that great. 6" was better. 12" is a beast, all with the same collector.

Just keep in mind, a collector like that gets hot as balls, and kicks back hot air into the room you’re working in (as well as a little bit of very fine dust). At our old shop, we had it in a sanding room and had to run the AC non-stop to make it comfortable in the sanding room. At our new shop, we have a dedicated room for our vacuum pump, compressor, and collector. Gets pretty warm in there, but stays cool where we do the actual work.

This is the dust deputy I run. Very nice because it mates with the Festool extractor. This setup is definitely for 1 person, but great for large parts as it’s mobile.

As far as large grinding bay extractors we ran the Oneida. As for ducting it’s a little more complicated than picking the biggest ducting you can. It’s very important to match the duct size with the extractor. Too large of ducting will mean that your liner airflow rates are too low and it won’t move the dust, especially important for vertical runs. Too small and you will have too much static pressure and bog the extractor motor down. Also be wary of putting an extractor in the grinding bay as the carbon dust can play hell with the motor and controller.

Of course. I just meant don’t blow all your money on the collector and skimp out on cheap, small ducting as you’ll loose efficiency. No point in running 4" ducting all the way through when you’ve got a decent setup and an 8" inlet. Having blast gates and wyes in all the right places helps too.

Buying the proper ducting made a world of difference for us.

Also the you can get just the dust deputy cyclone part for $50 and make your own collection box, just a matter of how much time you have to fart around. I have friends who took this route and made something much nicer than what you can buy.

Aint’ cheap, but I’ve always loved downdraft tables. Nice place to work on things, and all the dust just gets sucked down. Many sizes and brands, and many that you can make your yourself.

Another good point, easy to make yourself with plywood and plastic grating. It does require a pretty powerful extractor.

I’m using an articulating ten foot reach vac arm by Easy Flo, vacuum via a 5hp Grizzly wall mounted unit with double filtration plus a silk outer sock.

I was interested in looking at that arm, but the only thing I find is the central home system stuff under that brand, is my Google Fu broken?

Airflowsystems.com

Is the silk outer sock something you made yourself or purchased? I think we have a similar collector.

I tried to link my picture, but photo bucket and this sites file manager weren’t playing nice for some reason. The one I have is all aluminum and stainless.

The silk outer bag was from a previous system that I still had. I believe they still make them.

Hey all, do not forget about enviromental issues. Think about the dust and waste created, and then possibly filling your shop, OR outside full of carbon dust. That can be VERY toxic!!!

^Thusly I asked about extraction, if I wanted to know about backwoods methods, I’d have asked how to build a carbon filter out of HVAC filters, kitty litter, duct tape and box fans. I don’t think anyone here is leaving environmental concerns to the last thought, it’s our lives on the front line.
