Topic tags/keywords: question

I’m setting up a very small shop. Bandsaw, router table and maybe a thickness planer. Everything else hand tools.

Each machine will be used one a time. And there is no option to roll them outside and use them in the open air.

I want to keep it as clean as humanly possible and of course want to look after my lungs.

I’m more than a little confused by dust collection technology. I understand that you need two things. One, a power plant – the thing that does the sucking, either a shop vac or a dust collector. Two, a sperator which sits between the tool and the power plant and collects the big chunks before they get to the power plant. Furthermore, I understand that the power plant should have a HEPA filter.

Is that all correct?

Given that I am serious about lung protection, do I have to buy a cyclone – is that the only way to enable the HEPA filter to do its job, namely, very fine particulate collection? Or is there a smaller less expensive option that will work for such a small shop?

You can get a regular dust collector and get a pleated
filter for it, putting a plastic bag or trash can on the
bottom. There are also felted bags that filter down
to smaller particle sizes.

Can you show me what you mean by “a regular dust collector”?

In a small shop the dust will be even worse, same dust, smaller space. The planer will make the most, the others generate a lot of dust too. If you live in a warm climate you could blow it out a window. If you heat your shop that probably won’t be an option. The best option is collect dust at it’s source with some sort of collector or a shop vac and then install an ambient air cleaner to get the fine dust that the collector misses.

Doesn’t collecting dust at the source with a shop vac just blow the very fine particulates higher in the air? Can I collect them at the source rather than hoping to collect them later.

For the record: blowing out the window is not an option, there is no outdoor option of any sort in my scenario.

This sort of thing:

I guess they are “single bag” though they have two. Something in
the 700 CFM range will run on 110v power and be adequate for
your needs.

Penn State has effective dust collectors in a lot of configurations
for hobby shops.

As always, second hand machinery is a way to get more bang for your buck.

How many CFM should I be looking for? It will be used with a bandsaw or a router table that has two dust ports – one on the fence and one below the table.

Mine is just the cheap 16gallon one, not sure of the cfm. I use a hepa filter in the shop vac. I use it with my router (dust collection on the bottom). And my planer and table saw. I hook if to what I need to use.

I love my Dust Deputy. It has greatly improved the air quality in my shop. I has extended the life of the shop vac filter. I have a large Craftsman shop vac and the filter are expensive. I would go through 2 a year. Now I have the DD I have gone over 2 years and the shop vac filter is still good. Just my 2ยข worth.

You don’t necessarily need a cyclone, but you should have a good dust collection and air cleaning system. I would say more so in a small/tiny shop than in a large shop.

I have a couple of big Craftman shop vacs with Dust Deputies hooked to them. Google Dust Deputy and have look.
