New dust collector purchase

[dennis davidson]

I am planning on purchasing a cyclone dust collector for my small shop and looking at the Grizzly G0440. I also plan on venting the collector outside. It seems a waste to have to purchase a new unit which includes a filter and then not using the filter. Does anyone sell a cyclone collector without having to purchase the filter and assy.? The Clearvue unit is just overpowered for my needs. I called Grizzly tech support and they said they only sell the complete unit, seems like they are missing a market as I am not the only one who wants to vent outdoors. What have those that do vent outside have done in this situation?

Check with Oneida.

[Robert Payne]

Check with ClearVue Cyclones.

Try Penn State. They sell smaller DCs than the Clearvue you say is overpowered, and they're a smaller outfit than Grizzly so they might be interested in selling you a filterless DC.

If you're exhausting it outside, why not get a material handling impeller and forgo the cyclone/separator? If your worried about debris flying everywhere outside, build an enclosed "catch box" with a couple washable filters to allow airflow.

I took the bags off of this unit: http://www.grizzly.com/products/2-HP...ollector/W1666 Exhaust it outside and it pulls hard enough without the bags to support 2 4" ports open at the same time. I can run my planer at 25' away and my RAS @ 12' simultaneously without a problem (both 4" hoods).

I agree that if I could vent outside the last thing I would do is put an airflow-killing cyclone in the path. Since I have to breath my return air and want my filter to stay clean as long as possible, I use a cyclone.

I'm planning on doing this, and venting outside:

Maybe I'll luck out and find a cheap 2HP DC on CL with bad bags?

You could throw a stick in my area and hit 2 of them. Keep an eye on machinerymax as they have 2-3hp units come up all the time in the California area. $50-100 for shipping and you're good to go.

how severe is the problem of heavier dust and chips exhausted outside creating a problem for my neighbors and my shop.
can I get away with using this unit or should I put a Thein baffle on it? What is your experience with the exhaust air on yours.

[Justin Ludwig]

My DC is located 8-9' from the corner of my shop. It's 3' from a wall unit AC. Outside in direct line is a hill side and shrubs. Without a catch box, you can pretty much guarantee a radius of 15' for chips, minimum. There's no telling how far small dust particles go. Since you have neighbors, you'll most definitely need to build a box around the exhaust. Design something that can be insulated (for noise) and easily cleaned. 2x4 with 7/16" OSB and R11 would probably work fine and be built on the cheap.

To give you an idea of the noise factor: My shop is 40x80x16, which is connected to a 60x120x20. If my DC is running and I walk to the far end and outside (+200ft away) I can hear my DC running. Sounds like a dryer running that far away.
