Hi guys, it seems like the Harbor Freight 2 HP dust collector is the single most talked about piece of equipment on these forums by far. Questions about this thing just come up over and over again. So sorry if this review just seems like beating a dead horse, but I figure the continued and continuous interest merits a new review. And so without further ado:
Numbers
Per the manual
HP: 2
amps and volts: 20 and 120
CFM: 1550
weight: 103 lbs.
filtration: 5 micron bag
Price
Harbor Freight: $150
Note that the “normal” price of this thing is stated at $250. However, since Wood Magazine has had a $150 coupon almost continuously for a couple years now, I feel honest in calling the price at $150.
Price Comparison
Delta 1 HP: $269
Delta 1 ½ HP: $420
Jet 1 HP: $360
Jet 1 ½ HP: $499
Rikon 1 HP: $280
Rikon 2 HP: $400
Grizzly 1 HP: $182
Grizzly 2 HP: $300
All these models are roughly comparable. All are bags and not canisters. I'm sure prices are variable depending on sales, season, coupons, etc.
Packaging
This baby was packaged up pretty tight. Lots of padding and tight styrofoam. I think it could have fallen out of the back of a delivery truck or two and not taken any damage. I picked mine up from the store, and there was no damage or concern.
Assembly
Assembly was easy... once I realized the instruction manual was useless. Seriously, I spent 20 minutes looking for non-existent parts! I think the manual was actually for an older model with a different base. When they upgraded the model, I don't think they upgraded the manual. It was actually pretty simple to assemble it by just looking at the picture on the front of the box.
There were no missing pieces in my box, thank goodness.
Fit and Finish
I honestly don't have a lot of experience with other dust collectors to act as a basis for comparison. My dad has a 1 HP delta, and the overall quality of of the Delta does seem a bit more solid. But the Harbor Freight really doesn't seem too cheap by any means. In fact, it looks absolutely IDENTICAL to the 2 HP Rikon that's on display at a local Woodcraft store. It also looks quite similar to pictures I've seen of comparable Grizzly and Jet models. Overall, it handles pretty well and doesn't seem like it'll be falling apart any time soon.
People say that one problem with Harbor Freight is that their quality control sucks. It's not uncommon to get a lemon. Luckily (?) if if you get a bad one, they tend to break down quickly, and within the 30 day warranty period. You also have the option of an extended service/warranty plan. Many people seem to be OK paying for this since the product price is pretty cheap. I chose not to, and I think I got away with it since I've had mine for about 4 months with no problems. Your mileage may vary.
Performance
As stated above, the performance rating of this baby is stated at 1550 CFM. I have no way of measuring the accuracy of that statement. The most chip spewing machine I have is easily my planer, a Dewalt 734. The HF dust collector keeps up with it easily, with only a few random chips ending up on the floor or the planer tables. When it's on, the cyclone action in the collection bag is pretty impressive to watch.
The impeller has a 5 inch port, with a Y adapter. Both sides of the Y are 4 inch ports. I have one port hooked up to my machine and, oddly enough, it seems to perform better when the other 4 inch port is uncovered.
The 5 micron bag does allow very fine dust through. The toolbox I have sitting next to the dust collector gets covered in a very thin layer.
Accessories
I have a tiny shop, and I have no intention of spending the time or money putting together a full system of pipes and dust ports for each of my machines. Consequently, this quick release port system from Rockler was a great buy. I bought it on sale, but I think it's worth the full price just for the convenience. http://www.rockler.com/product.cfm?page=30200
My plans for the future include an aftermarket 1 micron canister filter from Wynn, and possibly a home made Thein separator. This guy on Lumberjocks seems to have a pretty good set-up. Maybe I'll just copy him. http://lumberjocks.com/projects/29578
Overview
At the end of the day, is this thing worth it? Heck yeah! I don't think there's anything that's comparable for the price. As I stated, I don't have a lot of personal experience with dust collectors, but I have no idea what a more expensive single stage dust collector could do that this one can't. This product comes with a high recommendation from me, and it's a pretty big improvement over my old shop vac based system.
Well, thanks for reading and I hope this was helpful to someone. This website's been great to learn from, and it's nice to be able to give something (hopefully) useful back. Feel free to ask questions.
Have fun,
Matt
