I think $400 is what it’s going to cost you to get a good, new 3HP motor. You might consider upgrading the impeller to a 12” design, as well. I know the HF enclosure can fit a 12”.

You don’t use all of the equipment at one time. Why not keep it 110v ?

Dan, I’ve been wanting to accomplish the same thing. I upgraded my whole dc system and want a 3hp 220v motor only (don’t need the bags bases on my set up). This is the most reasonably priced motor I’ve seen even though it comes with all the other stuff I don’t need. Its on my shopping list and when its in the budget I’ll get it.

If you get one before I do please let us know what you think of it.

Harbor freight sells some electric motors for pretty cheap…
I beleive any 3450rpm motor will work on a dust collector. I could be mistaken.

BTW, I have the Penn State dust collector with that exact blower. It works very well…
A couple years ago I think I got the whole dust collector for $350 shipped. I guess prices go up.

Thanks WoodworkingVet, PPK, mathguy1981, and WoodenDreams. I guess what I really meant to saw was that I am looking to purchase the entire blower, not just the motor but now that you mention it, that’s not a bad idea either. Good to have options. The Harbor Freight is capable of a $100 upgraded Rikon impeller that is 12”. For WoodenDreams, I would like to upgrade to 220V because I want more vacuum power but you end up being capped at 1.5HP or 2.0 HP on a 110V system because the amperage is just too high at 3HP. A 3HP dust collector is always going to be running at 220V or else it’s false advertisement or it is custom wiring from the circuit breaker to the unit. You’d need about 24-30+ amps for the 3HP dust collector. Considering I am wanting more vacuum, I’m going to have to step up to 220V which is no longer a problem for me. That Oneida does look like it has potential. I wonder if there are any reviews on YouTube for it. I’m always skeptical of purchasing non-reviewed things, especially for more than $20 much less almost $500.

Are you just wanting a 3HP motor by itself? Or the entire motor/blower combo? If you are wanting a blower/motor combo I doubt that you are going to find much as any company that manufactures dust collectors would have their sales numbers for complete units drop substantially. The only company that I am aware of that sells these is Penn State. If there were a 5HP motor blower available anywhere for a decent price, I would likely already have bought one as I have been looking for a decent used 5HP or greater dust collector. Keep us posted on what you end up doing.

Guys if yo ulook at the link he posted, its obvious he’s looking for a blower/motor, not just a motor.


First thing, is why do you think you need a 3HP blower? From your description of the set up, you might not need a unit that big. It all depends on the type of machine your collecting and the duct distance. Planers, jointers are very easy to collect shavings from. Saws produce dust and require a lot more CFM’s at the machine.

If you are not planning to install duct work, the Harbor Freight 2HP blower would probably do the job.

FWIW I’m collecting with a 1 1/2HP Jet 1100/Super Dust Deputy cyclone and 6” ducting. By all that I know, it shouldn’t be working very well, but in fact, it does an adequate job. I’m also ducting outside and that makes a huge difference.

The only reason I stuck with that blower, is I couldn’t find a 3HP anywhere (PennState used to carry one) and I didn’t think a 2HP would give that much more performance. I was in the same boat a couple years ago. I couldn’t find a 3HP blower anywhere except Cincinnati fan and it was way out of my budget. I think I heard Oneida will sell a blower only.

I thought I would resurrect this thread on the off chance that anyone had solved this problem—how to get a 3HP blower/motor combo without all the accoutrements? I’m in the same situation, have the Harbor Freight dust collector, mounted it on the wall and vented outside, but now looking to upgrade to 3HP as I’ve outgrown my dust collector by putting in too many 6” branches. My backup plan is to buy the Grizzly unit as it is quite reasonably priced but it seems a shame to buy all those carts and bags and adapters that I don’t need.

Cincinnati Fan sort of sells motor/blower only units in their portable dust collection series:

Last I looked the CF 3Hp 300s unit sold retail for just over $1000, without a drum. Even the Wood Master unit is ~$800.
Which means it is cheaper to buy the Grizzly/ShopFox/ETC 3HP bag units for ~$600 and throw away the extra parts.

Also – Have never priced the Murphy Rodger MR/MRT series 7 fan units , but often find them used on machinery sites for a couple hundred?
