do you want to plug in a DC and then focus on a woodworking project? Or do you want to focus on a DC project?

if the former… this is my recommendation

I believe it’s on sale right now for just a little more than the bag unit you referenced…. and it comes with a spun bound PE filter canister.

I have the HF 2hp dust collector. It is exactly the same unit that is sold by Rikon except the ikon model costs 3 times as much. The motor and impeller are great and have been working great. Works even better if you use some type of separator.

If you go with the Grizzly you STILL “have some generic Chinese motor and impeller”. You do have a mail order company that will most of the time stand behind their product and their attention to quality control is usually pretty good.

But, then again, I’ve never heard a complaint about HF customer service. If you have a problem in the warranty period they will swap for a new one.

When it comes to fine dust, 2 1/2 microns is no better than 5 microns. They both let the most dangerous fine particles through so you pretty much have to go to a cartridge with either machine to get better.

I don’t want this to sound like I’m bashing the HF unit, because it’s a great deal under some conditions and the perfect unit for some folks. But comparing it to the Grizzly is not a direct comparison. Unless they changed it, the HF is more like a 1.5HP motor (HF magic makes it 2 HP) and has, I think, a 10” impeller. The Griz is listed with a 12.75” impeller and it is probably a true 2 HP motor, listed at 240V only. Between the 2, I’d get the Griz in a heartbeat. It will still cost more, since you will have to do something about those bags (1 micron or better is my starting point). But you might be able to sell those bags (others with 30 micron are often looking to upgrade) and at least get some of the cost back. Or go with the HF without the cartridge.

Your approach with the Grizzly is not much better than chip collection in terms of health. Before you compare pricing equip each to protect your health then look at the numbers. The HF is highly regarded for the price I would compare the impeller size between it and the Grizzly though.

I have an HF unit and a separator. In 4 years, I’ve had no problems and it has plenty of power. I use it on one machine at a time and move the hose from machine to machine.
The micron size of the collector bags is of no concern to me. I vent it outside. Nearest neighbor is over 1/4 mi. away. But, very little dust gets past my separator, anyway.

I’m sure both are capable of the task, but they’re not really the same. The impeller size is quite a bit different, which ultimately equates to air flow, which can also equate to potential down the road. I also doubt the motors are evenly matched.

This pic shows a 12.75” impeller compared to a 10.75” impeller.

Fred Hargis: I realize it’s hard to compare the two DCs. I would have compared the Grizzly 1.5 HP DC but it is only $25 cheaper than the 2HP version. I figured for just a little more, I could have a true 2HP DC – both models from Grizzly come with a 2.5 micron filter bag.

After reading everyone’s posts, I was leaning toward the Harbor Freight DC until I saw the pic knotscott posted. What a difference! I need to give this some careful thought.

I don’t have a large shop: I use my large 1-car garage. Everything is very compact. I will probably just move one hose from machine to machine when I work. I don’t think I need to think about “down the road” as much. What I have now is most likely the limit of what I will need.

If I get the HF DC, and add the Wynn filter and a chip separator then I’m pretty much set. I guess If something breaks down the line, I could replace with a comparable or better motor or impeller for less than a new DC.

I’ll probably go out on Thursday to get the DC. I’ll post when I get it up and running. Thank you everyone for your help. And if anyone hasn’t posted yet, feel free to chime in. It’s not too late to change my mind!

I don’t know anything about the HF one, but I have a griz dust collector and it is fantastic. Haven’t had to add any filters to it and it works quite well. I use it on my CNC router which means it will run for hours at a time and it does this on a regular basis and has for months. No issues at all. I’m very happy with my purchase.

Dave – There’s no way I could have ever anticipated what my future DC needs would be as my shopped evolved. The separators work quite well, but they diminish the CFM a bit so be sure you’ve got good real world CFM. Air flow is everything in dust collection. I’d buy the best unit you can afford….if you ever add something like the Wynne filter, larger diameter ducting, and/or a cyclone to something like the Griz you’d have a very nice DC system with impressive air flow.

I don’t get why you’re looking at the Griz with a bag…. When the model with the canister filter can be had for just a few bucks more.

Lot’s of guy are having good luck with the HF… But the motor really isn’t pulling 2HP…. Certainly not with only 15 amps at 115 v.

I am having good results with my HF DC, but if I had the $$ for a real cyclone I wouldn’t bother with the HF unit… Airflow with that Grizz would be better, but that 2.5 micron filter is just going to pump the dangerous dust back into the air.

I have the 110 volt version of the Grizz with the canister filter. I added a shop made chip separator and have been very happy with the set up.

UPDATE: I have my 2HP Grizz Canister DC setup and have been using it for about a month now. I love it. Thanks for all the advice. It has plenty of “suck” and will probably serve me well for many years to come. My only reservation about buying this DC was the new aluminum impeller. To my surprise, it is a pretty heavy casting. It looks like it will be sturdier than a riveted steel impeller, though I don’t intend to torture test this feature. Time will tell if it holds up.

I have plans to build a chip separator in the future. Though, the way I follow through with my plans, it will probably be years until you see it actually built.

On a related note, your comments prompted me to explore other options which gave me the knowledge and resources to guide my father to upgrade his old Grizz DC with the 5 mic bag filter. He has purchased the Wynn filter. We are going to set it up and test it this weekend.

Thanks for the update….it’s always nice to know the outcome. Very cool about tidbit about getting Dad to upgrade to the cannister.

congrats on the grizz. looks to be a very good unit. i would humbly suggest the modification i made to my very similar delta 50-850 detailed in this thread:

http://lumberjocks.com/topics/40189

the positive impact it made on sending dust down into the collection bag and not up into the filter is incredible. even if you are planning on a separator, phil thien suggests that even in those applications with a pre-separator, the addition of a baffle to the drum ring of your style of collector is still advisable.

and while i’m humbly suggesting dust collection related subjects, check out these guys for automated dust collector activation:

http://www.ivacswitch.com/index.action

having the DC activate and deactivate in concert with the dust generating power tool really simplifies shop operations. i have 2 of the ivac switches in a daisy chain configuration and can recommend both the product and company as being first rate.

I haven’t filled the bag since I installed it, so the verdict is still out.

ssnvet….... looks to be a nicely executed version of the PT separator drum baffle. as your DC operates, does the collected material swirl to the bottom of the collection bag (as in my video of my DC) or does it lazily fall into the collector bag with no real evidence of a swirling motion?

I would get the Grizzly dust collector, get a canister filter too. Good luck!
