Topic tags/keywords: dust collection dust collector impeller question

I’ve heard people say that things can get sucked up into the impeller and they break. How many of you guys has that ever happened to? What brand of DC system do you have? What caused the damage? Of course, if it has never happened, I’d like to know what brand you have or why it’s never been a problem.

It would depend on what material the impeller is made of. If it is made of plastic or a cast metal, like zamak, it is possible for an object to damage them. Most impellers are made of steel with fins welded or riveted to the plate. Even if it’s made of steel, a cheap DC might use very flimsy sheet metal. If you are concerned about damaging an impeller, you can use a two stage system which allows large chips to be collected in a waste barrel before entering the fan portion of the DC. Only light dust will go through the fan.

I won’t say those stories are urban myths, because such things do happen….but it’s a lot less often than you may think. When I was running my single stage DC (a PSI DC 250, not discontinued) several times I had pretty good size chunks get to the fan and hit it. Nothing was ever damaged, though I did have to go clean up and change my whitie-tighties a few times. The impellers on SS units are normally a pretty tough/thick steel, and I think you are more likely to maybe bend a vane lightly, or possibly shear the key (not very likely, IMO). I suppose in a worst case happenstance, a piece could jam the impeller and stall the motor but it would have to be a number of circumstances all coming together at the same time. It’s not something to loose sleep over (again, IMO).

Vermin, (my HF dust collector), grabbed hold of a 2X3” piece of a cutting board glue up I did once.

Now, my DC is the cheap 1HP unit that HF offers. I did add another layer over the existing vanes that provided a bit less clearance. I used 5/32 aluminum alloy, but next time I think I would use a full 3/16”.

The 2X3 piece did no damage, but made one helluva racket getting swallowed.

Scared the peewaddin’ out of me, and I was incontinent for a few seconds.

I should mention I changed out the original motor for a 2.5HP Lamb motor that makes the unit about half as loud and 2.5 X as strong.
