Topic tags/keywords: dust collector harbor freight cyclone

Hi fellow Lumberjockers,

I was all set to pull the trigger on this…

My question is this…
Does it matter which side the inlet is on.
I have been reading that it should match the direction of the impeller and that it does not matter if your going to duct it to the cyclone, but it does matter if you mount the blower/motor on top.
Does anyone have experience with this,
I have been on Bill Pentz website and my brain turns to mush. I have seen too many pictures to the inlet on either side to make an educated decision.
Which side should the inlet on the cyclone be if I use the 2HP HB blower/motor, top mounted.

Thank you all, in advance

If you mount the fan on the cyclone like the picture is must rotate the same direction as the vortex in the cyclone. By the way, that fan in the photo is a screaming demon. Better put it outside if that is what you use.
The 2 hp HF DC fan will be starved for air with this setup.

Go here and read through the topics. hje Thein separator can be added to your dc ring for peanuts and work beautifully. Also, go here to get info on a caretidge filter for $110 that will be 99.9% effective down to 0.5 microns, will boost the dc’s efficiency, and save you money. I did this 2 or 3 years ago and have been happy.

Thanks, almost went with the impulse buy. Glad I didn’t. Crank49; I think you’ll be correct in placing the 2 hp motor on that cyclone will stave my system. and Fussy, I couldn’t see any pics, any other suggestions?

There are about 2,000 posts on that site, many with pictures. Rather than wade throught the whole thing, start with the earliest posts and see how it developed. Lots of the guys at first posted pics, videos and great discussions. The more recent posts just follow old work. Go to the beginning and you will find all the info you need. It is worth digging for. In three years, I have gotten less than 4 cups of dust from my fillter. The rest went into the bag. If you have questions after you’ve looked it over, just ask. I’ll be happy to help.
