Have discussed dc’s before but had a question I wasn’t really thinking about before. Thinking about the 3hp grizzly that’s on sale for $695. I’m gonna hook whatever dust collector I get up to my 8” jointer, cabinet saw, miter saw, larger planer when I get one and maybe spindle sander. I’ll only be using one machine at a time, would I be alright with a 1.5/2hp unit using blast gates on everything or should I splurge for the 3hp? I’ll have it situated in the garage to be near my jointer and close to my ts. My miter saw would be the farthest across the garage, might not end up using it on that because I’ve heard it doesn’t do well with the smaller dust collector slots like on miter saws. I keep pushing off buying one for some dumb reason and need to just bit the bullet and get it done.

I will give you my absolutely non-expert opinion: according to Bill Pentz, the 2 hp will easily pick up all the visible dust, but you need a 3 hp minimum to get the microscopic dust that is what will really do you harm.

I have a 2 hp, btw.

Could get the 3hp without canisters for around $200 cheaper, or get a 2hp with canister for the price of the 3hp without canisters. Either way, one bad thing is that I’m going to have to run a sub panel in my garage, out of room on my panel and my saw and jointer run on 240v as well.

If I read the question correctly (always a problem for me) it sounds like you were going to use blast gates with the smaller unit, and not with the larger one? If so, you will need blast gates regardless of which unit (of those 2) you select. Personally, I would suggest you get the larger one if you want to get as much of the fine dust as possible, if you’re looking to get most of the chips and some of the fine dust, the smaller one will do well. Check the bags, you would want at least 1 micron filtration, any larger will just recirculate what fine dust you do capture.

I have both the Jet 1100 ( 1.5hp ) and the Jet 1900 ( 3hp ). Get the 3hp especially if you are running 6” duct. The 1100 is ok using it to connect to one machine at a time (not using ductwork), but time you have losses for duct it is not as effective. The is a very noticible difference in air flow between the two. I had initially bought the 1100 new and then got the 1900 used for 1/2 the price of the 1100.

Joe, you probably already know all this but the cost of the DC is about 1/2 the cost of the total collection system. The tubing and fittings will be more significant than many people anticipate.

You can also improve the efficiency of your system by running 6” rigid tubing to as close to the machine as possible, then a blast gate, then 5” flexible tubing to the machine’s 4” dust port. Locate the DC as close to the biggest producers (TS, jointer, planer) as possible. Keep the runs as short and straight as possible. Use two 45 degree elbows instead of a 90 degree elbow. HTH

I have been very happy with my 110 volt Grizzly with the filter cannister. I have a 4” hose that I take to each machine. I built a simple chip separator from Shop Notes that works very well with my DC. I have 10 feet of PVC pipe from the separator connected to 8 feet of flex hose.

Id def have blast gates for any unit, just didn’t know if having a 2hp with those would suffice. My garage is a mess and dusty as heck bc I don’t have a dc and that’s just not smart health wise, especially since I’m 28, would like to live a long life and do this. Having a 110 unit would be nice bc I wouldn’t need a sub panel, but Id rather run the panel and have adequate suction for everything.

I would also consider the noise level of each before deciding.

Given the description, go back to what Charles said said. Capturing the fine dust takes a little more, so you want as much air flow as possible. That not only means the larger DC, but you have to have duct work to support. Buying a large DC and choking it down pretty much negates any advantage it might have. That goes for the tool ports as well, most tools have small or even puny ports, opening them up by whatever means necessary is just as important. The high air flow at the tool will get the finest particles. Just remember, even a world class DC set up won’t get everything, try catching the dust from a router or maybe a miter saw is a real exercise in frustration. The other thing to pick up on is Art’s point about the cost, that is the ducting will be (probably) as much as the DC, and finding 6” PVC is not easy. Good luck with your effort.

Didn’t think about how expensive duct work would be. Really had my eye on grizzly’s 15” spiral head planer, not sure that will happen once I get a dust collector and all that. Sucks neither show up on my craigslist very often.

You might have a bit better luck with searchtempest.com. It searches all CL in the desired radius plus ebay, Amazon and maybe others.

Never used that site before, just saw a grizzly 15” planer and dc but of course it’s sold, will have to keep an eye out.

Have your say...
