Topic tags/keywords: dust collection

I am pondering a new dust collector and I generally like to buy something I know I wont have to replace. I have an OLD OLD OLD jet rollaround which has not been as painful to use as I would have thought, so I’m open to a portable unit. I don’t have a lot of pressure on pricing, but I really can’t count on 220v.

My question is this… is a “portable”able to be used with a hose of any real length at all? My hose is only 4’ long, but if I upgrade I’m hoping to get something that will work at about 10’. Am I crazy? Will that work? What type of distances are people pulling dust and feeling good about it?

it depends.

“portable” comes in many flavors.

I have the older Jet 1100DC – it has wheels, but it has never moved from it’s corner. I have it connected to both my TS, Jointer, Planer, Bandsaw, and extra port for workbench. has 3 Y Splits, and longest run is ~20ft – works great.

Thiel, I agree with Sharon’s comment. I have a “portable” Powermatic that I rarely move. I have two 20’ lines hooked to it. I keep one on my table saw and the other I move between my other tools. To get the best performance out of each line I have blast gates hooked up in-line and close down the one that is not being used.

I use my portable the same way as Scott and PurpLev, I have two ~20ft—runs of PVC with blast gates and short flex hose at the different machines, works good for me.

So… with these 20’ runs, how many CFM are you pulling with your machines?

Here’s my confusion:
—Jet 1100 gives about 1000cfm for about $400
—PM 1300 gives about about 1000cfm for about $700
—Grizzly G0443 gives about 1000cfm for about $900
—Oneida V-1500 gives about 1000cfm for about $1100

I know I’m oversimiplifying, but there seems to be a huge disparity in function/price…. or is it that if I settle on a CFM rating then I’m just debating features and options (e.g. loudness, bag size, remote included/not, etc)?

You guys seem to be saying that around 1000 cfm is sufficient for a one-machine-at-a-time shop which is around 20’ long. Yes?

The problem is that you can’t just look at the cfm rating, because the real question is the cfm under what conditions? Some manufacturers rating is when the DC has no ductwork and no outlet filters, in other words just a straight path. Put on filters and 10’ of flex hose and that flow drops to 350 cfm.

Most people don’t have the equipment to measure their true cfm, so most won’t be able to tell you.

A more relevant thing to look at is the fan curve, which shows the cfm as a bigger load is placed on the inlet side. While you can’t really trust them for absolute numbers, you can learn something about them from the shape of the curve. As the load (static pressure) rises, the cfm drops. Some DCs have a very steep curve, i.e. as they’re loaded their efficiency drops off rapidly. Others are much flatter, they might only lose 40% of their capacity as the SP rises from 0 to 10 inches. But again, you have to wonder exactly how the testing was set up and most companies will not share that data.

I was really torn between an Oneida cyclone and Grizzly’s G0441. The deciding factor for me was fan curves published on Oneida’s own site showing the Grizzly outperforming their cyclone at higher SPs. My shop will have some fairly long duct runs and the curves (IIRC) showed the Oneida effectively moving nothing at 10” SP while the Grizzly was still moving several hundred CFM.

On a side note, keep in mind that the ductwork for a cyclone can get quite expensive. I paid $1350 for my G0441 and I’ve spent almost that much on ductwork and other ancillary stuff like a sound closet (that sucker is LOUD).

The dust collector I’m using is a 2hp General International with canister that I paid $700.00 cdn for. And hooked up as I posted before it works very good, as for how much air it is moving at the machine I can’t say for sure, but it makes my one man shop allot nicer place to work. I think a 2hp machine or larger will all be 220v. I think that a dust collector of this size will keep up to most one man shops easily.

My JET works perfectly..Yes it has wheels , but it remains in the corner of my shop and I just run a hose or hoses to what ever machine I’m using at the time.I also have one of those cyclone lids that fit onto a metal trash can just before my DC.It’s so nice to empty a can versus having to remove a bag from the DC. My Jointer and Table saw are on the same hose with a Y in it and I just close the blast gate to whichever one I’m not using. I also have a smaller 1HP unit that I roll around to different machines with an 8-10 foot hose on it.The small machine was wired for 220 or 110 , so I switched it over to 220V and it seems to run much smoother and more easily for some reason. I’m probably going to change the wiring on my big JET as well , because I had my shop wired for both 110 and 220 with all new receptacles and its own subpanel by a professional electrician.I sleep easier that way . LOL
