I have a shop out in the country its a large shop 32×48 with lots of room outside the shop, I would like a dust collector that simply blows the dust out into a box then I can take a tractor with loader and dump it. Would like to have just a suction type system that would simply pull the dust and blow it outside no bags or anything, Is there some kind of system that does this thats not real expensive and simple to set up? maybe a dust collector modified. all suggestions are more than welcome

Sure, all you need is the fan and ductwork.

One small problem is the fan you need would be way more expensive than buying a dust collector.

For example, a 2 hp motor on a centrifugal fan that can generate about 7” static pressure will cost about $800.
A 2hp Harbor Freight dust collector, as mentioned on this site all the time, is available with a coupon from any woodworking magazine for about $160.

I suspect that blowing it into a “box” might be a problem. You need a way for the air to vent….but once you overcome that there’s no reason your idea wouldn’t work. It might be a lot easier to buy a sizable single stage DC and just use the blower off it, letting it discharge into whatever collection device you cobble together. The criteria of “not too expensive” may be a little tough to meet, depending on what that means.

Good advice from the previous gents. Also, keep in mind you should have your dust collector motor, fan, electrical box ideally under a cover to keep the rain from rusting it all away. I agree w/Fred that you can’t just put it in a box w/o venting it. I say, you get yourself a dust collector-used- off Craigslist or go the HF route, and use the bags it comes with. Otherwise, you will literally have dust all over the place (which isn’t really an issue I take it) but will make it difficult to gather with a loader.

By the way, we are all assuming you create fine dust as well as coarse. What size dust particles are you creating?

thanks guys I really just want to put the motor inside maybe mounted and just hook a line to my jointer and planer and then blow it outside into a large open box say 5×5x5 and then I can take the loader and pic it up and dump it. does that make any sense I know Im crazy but anyway I live on a farm with nobody around so I can basically do anything, can i just take a harbor freight motor and take the bags off and just use that as a blower would that work? why Im asking is does the blower or motor have to have a little resisitance when pushing the dust out or is it ok for it to just blow freely outside?

You will need to measure the current draw of the unit. It’s possible, though maybe unlikely, you will overload it without some restriction on the discharge. Depends on the unit, the ductwork, and a few other things. BTW, doesn’t sound crazy to me. If I could deal with the heat loss, I would vent outside.

yes the box will be open with a cover on top then I just scoop it out or pick it up with the loader, answer to question I will be using it for jointer type dust but i might use it on the tablesaw later if it works I would like to keep my shop uncluttered if I can help it, or not so cluttered as it is, I mean my shop isn’t fabulous or nothing it’s just a Morton pole barn Im goin to try and lower the ceilings some day they are 14 feet really to big think I might partition it off later

I say go for it. Sounds like it will work fine. Fred, Those small HF fans should work fine because he will still have static pressure from the feeder lines themselves.
Also, with those heavier chips, this all sound like it will work fine.

In the olden days I had a shop out in the serious boonies and for the general airborne dust I mounted an old 16” squirrel-cage blower out of a junk furnace into an opening in the back wall and let it blow out into the woods. It worked great, moved tons of air very quietly, but it was only usable in nice weather, and that might become an issue for your idea of blowing the dust outside. Whatever air you blow out of your shop needs to be replaced from somewhere, and in cold weather one needs to be conscious of where incoming air source will be! A standard DC does not remove air from your shop, so might be a better year ‘round alternative. My current DC system fills two 30-gallon containers every month or two, and I just take them outside and dump them to use later as soil amendment.

I put a separator in front of the blower to keep offcuts from getting in the blades, I hate it when that happens, it makes a loud bang every time!

If you do blow the dust into a box just put a couple of furnace filters on the top of it to vent the air. They will retain most of the dust and virtually all the chips in the box.

Keep in mind that this will crucify your climate control efforts. Any air that gets blow out of the shop will be replaced by outside air that gets sucked into the shop.
