Harbor Freight dust collector impeller wobble

Defective. I would return.

I’m not a major fan of the HF dust collector but first, you could at least just take it back and exchange it for another one. Usually that’s pretty easy to do there. Then you can try some mods but really, after you start doing that, the bang for the buck starts to decrease.

Rather than mess with upgrading impellers, I would just get the 2hp Grizzly. Ater you figure the cost of the impeller and the time you put in, it’s cheaper to just get the bigger blower. Also, if you get the bigger impeller, it would really be helpful to change the intake on the housing to 6”, which is something else you’ll have to put some time into. Then, 6” hose, etc…

I know this from experience. I’ve done the mix and matching and trying to make cheap things work like the more expensive ones and learned the hard way that I’ve spent a lot more money in the end than if I had just bought the bigger units to begin with.

If you bought it new take it back…
I’ve had mine maybe 6 or 7 years and it has always worked well and as quietly as my Penn State DC.
I’m pretty selective about what I buy from HF. Some stuff is fine and some isn’t. Knowing which is and which isn’t is a learned skill.
