Hello all!

My name is Matt, and I am new here. I have been playing with wood for many years, though in the past it was mainly a side part of another hobby (like an end table to house a subwoofer in a manner that was acceptable to the wife).

I have recently decided I want to dedicate some time to the hobby itself, so I have started the process of converting a small area into a dedicated wood shop (about 12×16), and purchasing some tools as they come up for sale locally.

One of the items I was able to obtain is a Grizzly G0703 dust collector

My plan is to locate this outside of the shop area, run piping through the wall, and have a few drops for tools. I am planning on a pretty simple 6” duct system with similar sized drops (from what I can figure out on Bill Pentz’s site) to handle reasonable “chip collection”.

Right now the tool “inventory” is looking like:

Table saw
Midi lathe
17” bandsaw
drill press
Some sanding items (disc/belt combo, maybe others)
Probably a lunchbox type planer
and hand tools to handle other things

I have learned in my reading that the DC I have will not be sufficient for the fine dust, so I am thinking about a hanging air cleaner/filter to assist there (the smaller ones should be able to filter the air more than 10x per hour), or possibly finding a room sized HEPA filter as an alternative.

Am I headed in the right decision, or setting myself up for disappointment/failure with my dust collection/air filtration plans?

Yes your on the right track. The dust collector you have is great but the addition of an air cleaner would complete the job.

I agree. I have done exactly what you are planning. 6” duct for dust collector and ceiling hung filter/fan.

Thanks for the confirmation. I am a little surprised that there is so much discussion on dust collection, many in the 2-5k price range with ducting, rather than using effective collectors plus secondary filtration. Any idea why it isnt more popular?

I run 3 DC units outside there’s no reason to control the fine dust outside if you have the whole unit outside the idea of collecting finer dust is if the DC unit is in your workspace.

Jim, I am not sure I understand your statement, can you help me out a bit?

My dust collector will be outside my workspace, and I am figuring the ~.2 micron filter will be fine in the storage area.

The secondary air filter is to control fine dust in the working area, knowing that the DC wont be grabbing it.

Yes, exactly. either one of the hanging filter systems, or maybe a room HEPA filter, something along those lines for in the shop area.

For lack of a better description, a 16×24 building cut in half, one side is storage/lawn care stuff, and the DC will be over in that side, with the other half of the building being the workshop area.

Have your say...
