Topic tags/keywords: grizzly cyclone dust collector question

Does anyone have any experience with the Grizzly G0703 1 1/2 hp dust cyclone, or the Grizzly G0443 1 1/2 hp dust cyclone? Do they work well? Any problems?

I don’t have either I have an Oneida but from a design standpoint the G0443 looks to be the better of the two. From what I’ve read and learned and if memory serves me right the longer narrower less angled cone on the G0443 is supposed to be better along with the square sloped inlet is also supposed to be better at improving the separation. A lot of this comes from Bill Pentz’s site.

I do not have a Grizzly cyclone. I have the G0548 2hp with the canister. I have not had any issues with the unit so far. I have used it for about a year and must say it will suck the chrome off a trailer ball. I did look at the cyclones when I was “shopping” but opted for the portable unit as I am limited on space in a 2 car garage shop. My only complaint was with the location of the switch and the short wiring that came on the unit, and its not wired with a plug. I did put a remote control on the unit and it done everything I have asked of it. I have it hooked to 2 machines and use dust gates to control flow. I am considering making it permanent in a corner and running rigid piping to my larger machines. I have heard good things about the Grizzly cyclones but for me it wasnt in the budget and I didnt have the room.

I have been looking at the same two and I have a puzzler. They both have 1-1/2HP “F Class” motors, the G0703 has a larger impeller (13-1/2 vs 12-1/2) and yet the G0443 has significantly higher flow at higher pressure. How can this be? All I can figure is that the half-area-filter (48 vs 96 sq.ft.) on the G0703 is essentially plugging up the blower. Anyone understand these machines better?

Your assumption is correct. They are using the lower filter area to increase static pressure which significantly restricts the air flow. This is probably being done on purpose to minimize the amount of air which the impeller moves. Moving too much air will burn up the motor. One way to move less air is to decrease the filter area. Another is to decrease the impeller diameter.

Blankman, Bill pentzs website is really informative, but I find that it is extremly Biast.
