Topic tags/keywords: dust collector blower motors dust collectors dust motors 3 hp 220 v

I’ve got the Harbor Freight Dust Collector like 50% of the rest of you and I just had my garage’s electrical system completely overhauled. I was operating entirely off of 2 outlets only, each on a separate 20A circuit. I have a Dewalt table saw, Cutech 8” jointer, Cutech planer, Delta drill press, Delta miter saw, California Air Tools 4.6 gallon air compressor, and numerous hand tools. It was a challenge. I’ve now got a 100A panel wired to the garage with (5) GFCI 110V circuits and (2) 220V circuits. Now it’s awesome!

There are a few modifications I’d like to start with and for some reason, I SWORE that the Harbor Freight dust collector could be wired to 220V but after looking up how to do so, that doesn’t appear to be the case. I’ve got a 55-gallon fiber drum as a separator and have 4” hoses run to two locations where my portable tools can easily connect to them. I’m interested in swapping out the bag filter for a cartridge and going with a 20-gallon fiber drum that I can empty more frequently and easily. I will add a cyclone or Thien baffle to it as well but the hardest modification that I am trying to find is, instead of having to purchase an entire new SYSTEM, I’m interested in just buying a ~3 HP 220V single phase motor that I can then mount to the wall and attach to my current setup. Obviously, I don’t want to spend an arm and a leg but it seems like everything that is available comes with the bags and filters. If I were to get a 3HP motor, I may consider leaving the 55 gallon drum in place and going with a very large canister filter but the only thing I’ve found available for sale online is from Penn State Industries which is just a 2HP 1350 CFM motor for $400. Here’s the link.

This is EXACTLY what I am looking for except that the item itself isn’t powerful enough to run the eventual piping that I will install. I think the dust collector is the first device that I want to power using the 220V capabilities that I now have. I’m trying to keep the cost under $600 IF the motor is sufficiently strong. I like the power that you can get from the 3 HP line of dust collectors and think that it will suit my shop well; especially after I pipe it throughout. If you’ve been down this road before and had no luck, I’d like to know what you settled on and how it works for you. Obviously, if it isn’t feasible to just purchase a 3HP blower motor, and you’ve selected a Shop Fox 3HP or Grizzly 3HP system, for example, I’d like to hear how well it performs. I’m happy with the Harbor Freight system as it is set up but I’d like to expand my shop and the vacuum capabilities so that I can set up “stations” for my tools instead of requiring all of them to remain mobile. I’m leery of the reported CFM that are advertised on these blower motors/systems because they’re usually determined/measured by the manufacturer and if your income was made by making and selling cakes, would you tell anyone that it is bad despite your honest opinion? Maybe they are accurate but I’ve got to hear some personal testimony and recommendations before I’m going to bite at the advertised bait.

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.
