Hey guys, I live in a wooded area and thought about removing the top bag of my dust collector and maybe using a cone to go down to an 8 or 6 inch pipe that I could run out the back side of my shop out in the woods. Any ideas good or bad? Looking for any and all input. Thanks in advance, BTW I have the 2hp Harbor Frieght unit

Are you talking about making a shop made cyclone?

not really, instead of using the top bag for the fine dust, just blowing them right out the back of the shop out into the woods. That or may just take the outlet of the fan and pipe it straight out the back, but would like to maybe catch the larger chips first.

Why not let the chips fall where they may?

Been thinking of turning my 1HP Grizzly into a cyclone. Then I could use a plastic 55 gal drom for the collector. Been pondering this for sometime now.

Why not just lose the inlet ring all together? Just run a pre separator like my Thien cyclone separator, then your impeller housing, and instead of piping to an inlet ring and bag, just take the house out the side wall of the shop? I am in an HOA controlled community so that wouldn’t work for me, but if you can get away with it, why not?

Do you want the chips and sawdust out there?. It may end up looking like an old rusting car, if you know what I mean. Check out dbHost’s stuff about a preseparator in his projects, then you might blow the rest out…........

Thats what I do. I have mine piped up into the attic, then outside. There is not much dust to speak of that collects at the end of the pipe. The breeze takes care of a lot of it and the lawn mower scatters whats left.

i live in the country and took my bag off the day i bought my dc..it will increase the amount of suction for your system and you wont have to empty the bag anymore…i put a yconnection on the outside with a 12”extentsion…so it blew it away from the shop….you dont want to attract termites close to your shop…if you garden , you can shovel it up after awhile..it will have composted and will be good for potting soil or the garden..but you have to allow it to break down for some time..or it would be to acidic…but i would if i were you…that is remove the bag…...

The most important thing to consider when venting outside is the negative air pressure the DC can create. If you have a chimney that vents your furnace and/or hot water heater or a wood stove, the DC can pull air back down your chimney. That could be bad. If you have a window or door you can open while venting the dust outside you should be okay.

Other than that, I’d try to pipe it as far from the house as you could, you don’t want the fine particulate blowing back in open windows in nice weather either.

If you do decide to vent outside with no bag, you should see an increase in the volume of air that the DC can move.

The Thein Cyclone separator lid is the way to go in my opinion. Like dbhost said, if you make one, you could eliminate the inlet ring and collection bag and run the outlet of the impeller housing directly outside, all while improving the efficiency of the entire system. AND, you’ll never have to buy bags again!

Good luck!

I had thought about doing it that way, and probly will. As far as bugs and things the wood come right up to my shop any way and I was thinking of piping it atleast 20 foot out into the woods. Thanks for all the input

You don’t have to worry about pumping all of your heat outdoors, like here in MN.
