I asked about DC before but I want to narrow down some questions. I am wiring my garage for 220 (will have a 100A subpanel). right now I have a sawstop table saw, powermatic jointer and a delta planer that will have a 4 inch dust port.

Qustions, do I need a 220V DC? I was looking at This Harbor Freight Model, on sale.

Also I was looking at Rockler.

Do I need some sort of canister cyclone to go with this?


PS, my budget is under 800 bucks.

im far from an expert on dust collection but id say those are both too go with a 2hp 220v cyclone collector,or you’ll just be wanting to upgrade in a year or two.

I’m anything but a fan of the HF DC, but it’s in a different class than that Rockler thing (well, maybe not…but it’s a damn sight better). I’d suggest you go with the biggest DC you can afford.

I would go for a 3 hp cyclone.

I for one suggest you go for bigger than those two… Dual bag or cyclone type if you can afford it… I also recommend a Super Dust Deputy front end for any non-cyclone unit.

Dust collection is something you don’t want to skimp on and consider expansion… you may be getting a nabdsaw, drum sander if you really get serious. You could also use a scoop to collect at a lather… this is rather futile but better than nothing.

I think you should allow space in your panel for a two pole breaker for the DC. That way, you’ll be able to easily adjust to match whatever DC you decide upon.

If you go with a 120V unit be aware that some people have had issues with a few models getting them to operate on a 20A circuit. You might want to install 10G wire to be prepared for this.

With your $800 budget there are much better choices out there than either the HF or Rockler. See some of the Grizzly offerings, e.g., G0548 or, for a bit above budget, G0860 or W1823.

I started off my shop DC with a 2hp cyclone, and found it lacking and went to a 3hp cyclone. Much better, but the biggest improvement was when I built a 8” dryer type vent and started blowing outside. Twice the suction as using the filter. Most of the year I use the outside dump, and only down side is running the barrel over. Coldest days I run with the filter, to not lose heat, but only a few days. Only time I notice any dust coming out of the vent is when using my wide belt sander. And most of the sanding dust is in the barrel. That and when the barrel is full.

Have your say...
