It sucked a 6" duct oval before the duct failed. This is an amazing product. A good buy for anyone. Tonnes of power, lots of suction. It has a huge amount of suction power. I made the mistake of not opening a blast gate at a work station before turning it on.
Indoors (basement or ground level) or Outdoors (meaning garage or barn, ect).Now I'll tell you why you should think of these issues. Third, what kind of shop do you have. And, yes, I normally ware a mask. (Maybe I'll get a 30 micron or larger top bag later). Second, how many 220v circuits do you have. Good suction and runs smooth. For those of you who are looking at a first dust collector I might recommend this one based on a couple of conditions that you should think about, that I did not.First, how much suction do you need, and how many machines will you be running. I gave it the 5 star because I can't blame the machine for something I didn't think of when I bought it.
And being able to plug it into a 110v outlet would have been nice letting me put it in a lot more locations if I ever need to do so. But maybe you will if it's not just you. This was the first dust collector that I bought. I'm going to compare this to the grizzly g1028z and why I might have bought that instead of this in hindsight. I wanted also wanted the smaller micron bag, which I hear makes the suction less, because my shop is in my basement and I wanted the better filtration.
If you have a personal shop, I don't know how you will be using a table saw and a planer at the same time. I'm pretty sure the 1300cfm would have been enough since I only use one machine at a time. When I bought this I thought bigger and stronger is better right. I bought it new from Grizzly a couple months ago.
In fact a bag that didn't go down so small probably would give me more suction. What I did was put a larger thick bottom plastic bag around the top bag with an exhaust port expelling the sucked air out of the shop altogether. As far as the performance goes, no complaints I guess. Well, now that I got it, it still does not filter enough (I also have a couple.3 micron filters too) to keep my allergies from going crazy for a few days after being in my shop from a couple hours of work. So since it's expelling all the air, the filtration of the bag is not really that important any more.
They're also almost the same price. Now that I've got the new circuit wired, it's not a problem and I'm glad to have the extra suction. Hope this was helpful. So the convince of the 110v over the 220v was the only thing that I had buyers remorse over because I'm sure 1300cfm would have been enough for me. I've read about some people talking about multiple machines to run off of it at the same time.
So I had to put up a pretty elaborate ventilation system using the dust collector and a number of exhaust fans to constantly replace the air in the basement. The 1028z pulls 1300cfm while my 1029z pulls 1550cfm. Because you'll need more then one if you get this. Well, maybe it is.
However, when using the contractor's table saw there is still about 25% of the dust left on the floor which is expected. At this point I am only using one 10' hose and change it from one machine to another. I use it in a small garage with a contractors table saw, Grizzly 14" band saw, De Walt 13" planner, and I built a drill press table for drum sanding purposes with a 4" dust collection outlet.
Since I purchased this machine there is no longer dust on the car after a week of work in my shop. Also, make sure you shake the dust bag on the machine periodically to maintain optimum air flow.In the interest of health safety since the dust bag on this machine filters down to 2.5 micron particles, I would recommend that I recently purchase a Powermatic PM 1200 Air Filtration system that hangs from my garage ceiling and filters down to 1 micron particles. If you are going to run a duct system to multiple stationary machines, use a blast gate at each machine and open one gate at a time to keep the cfm at its highest.
I've had this machine for one year now and it has served me quite well and I would highly recommend this product for a small shop or garage application. I also use a table dust hood when sanding with a belt sander and it does a fantastic job keeping dust out of the air and off my project. You might consider a final air filtration system similar the PM 1200 to complete your dust removal system.
Dust collection is excellent on all these items. This is due to the fact that the saw is not a closed system but a cabinet saw is in the works in the near future.
I own this machine - bought directly from Grizzly - this is a great dust collector - does what is promised - If I had one complaint, it would be the on/off switch is hard to access - beyond that, I don't understand what everyone is complaining about, mine works great, and I think will work even better when I connect a main 6" common return with branches off to 4".
Welded metal impeller (Will cause sparks if any metal hits it- dangerous). If you must buy a low cost unit, look at the JET (that has an alloy impeller and better construction).
Not a whole lot of suction, even with a single, short 4" hose. I doubt that the 2.5 micro figure on the bag is anywhere close to accurate.
I've used this thing daily for about 6 months now. Cheap, imported 220 Volt motor (FYI- USA is either 240 Volt single phase OR 208 Volt 3 Phase, period).
I am buying a proper USA made 3 HP Oneida unit next, as cheaper in this case is false economy. Thin, flimsy sheet metal construction (the area around the impeller is bent around every screw).
Leaks dust like crazy.
