I know the 2Hp is on sale right now for $139.00 and there is a 20% off coupon in Wood mag. Don’t know whether they will take it also on the DC. Everyone raves about the 2HP HF DC but does anyone have any experience with their 3HP one? Is it worth the extra bucks?

No experience with the 3HP but I’ve been very satisfied with my 2HP. I’ve had it the neighborhood of 9 or 10 years and it has yet to give me a lick of trouble. Just guessing here but I would assume that the bigger one is made in the same factory as the 2HP so the main difference would be only the motor. BTW, if that $139 price is advertised on what they call a “Super Coupon” then you can’t pile on the 20% off coupon.

Love the 2 hp. When I bought mine, they would not take the 20% off the sale price. I do think it is “employee specific” however as some will and some won’t. At $139 it is a bargain; at ~$112 it is incredible!
Do get a better filter, however… recommend the Wynne.

More HP is always better until you get up in the range of a 5HP motor (and a 15” impeller). However, it’s more important to upgrade the filter than increase the HP. If you have enough $$ to get a .5 micron filter AND the bigger unit, go for it, but if you can only do one, get the filter.

ellen35 I’ve seen how people have changed the filter and enlarged the intake to 6” on the 2HP. Can you do a separator with a 6” intake and output?

I have the 2 HP and put a canister filter on the top. Good value out of the box. With canister – much better power and suction.

I think you can do it with any size intake. I have used a separator with 2 inch intake and output. You actually get two intake ports – both 4 inches. I don’t see why you can’t use 1 as a 6 inch. I find that I don’t really need the separator as the collection bag is very strong.

I disagree, ‘my” stores ( 2) always accept the 20% coupon , on anything and even two coupons for two items.

My 2hp has never been over taxed. Do get a separator, though.
Mine is vented outside. So, can’t comment about bag options. It does seem to have more suck than before I vented it outside.

Do not want to hyjack the topic here, but Gene, you mentioned you vent your HF DC outside. How much of a performance upgrade was that?

I am also thinking of doing this, however I live in MN so winters here are a bit chilly and I would need to supply some serious make up air. I have been so wrapped up in a few projects I have not had the time to test it out. Now that we have snow, the days of having the overhead door open are gone.

To the OP, the 2HP one works great out of the box. I have not modified mine at all yet. I do plan on getting the filter as others have mentioned if I do not go the outside venting route. If I go the filter route I will be raising the motor to allow a direct inline flow to the filter.

One point to consider with the 3 hp unit is the noise level. Their website says 99 db. I have a noise level app on my phone that says my 2 hp unit is 85. Not sure how accurate it is, but if it is, the 3 hp unit is going to be very loud.

I have yet to see one of the 3HP units up close and in person, however I did stumble across a Youtube video of it yesterday… It seemed pretty solid. However honestly, I am very pleased with my HF 2HP DC. The $139.00 sale is on a super coupon, and they won’t let you use the 20% off coupon along with the super coupon, or if they do, they are doing something they aren’t supposed to…

I like my HF 2hp DC a lot. It comes with the fan inlet diameter of 5” and with a “wye” fitting that splits into two 4” ports. I have one of the 4” ports connected to my table saw and the other is reduced to a 2-1/2” hose that runs to my band saw. Alternately, I connect the collector to my jointer and planer using the same size ducts. This collector handles either of these setups with two ports being open at the same time just fine. The cross sectional area of a 3” and 4” duct would be exactly equal to the 5” fan inlet so that combination would be balanced and use all the capacity of the fan.

I am working on a cyclone type separator to install in front of the fan because I don’t want all the chunks, screws, and shavings going through the fan impeller like they do now. I will probably only have this on the 4” line (table saw or jointer). If I wanted to run everything through the separator it would have to be a 5” duct between the separator and the fan inlet.

I take a different approach from others here in that I feel a shop air filter that I can run all the time is money better spent than upgrading the collector bag to a Wynne filter cartridge. I don’t want to listen to the collector running all the time because it is noisy. If you go with the 3 hp machine it will be even more noisy. The shop air filters are much less noisy because they don’t have to develope the high static pressure to pull air through a tiny pipe at 4000 FPM. They use the same kind of fan as a central furnace or central air system uses and just have multiple stages of filters to get the air cleaner than even the cartridge type filters.

By the way, my HF would not let me combine the 20% off coupon with any other sale or coupon. It’s printed right on the coupon that they will not, so I was surprised to read that some people are able to do this.

crank49, there are others who have the same setup as you. I’m mystified why anyone would throw harmful particles (.5 to 5 micron) into the air and breath them until the air filter picked them up. I’m sure you don’t have an air particle counter to look, but FOR SURE, you are breathing unhealthy air until several minutes after you shut off the power tool, and the air filter can suck up what is left in the shop air. You are breathing less of it than if you had no air filter, but it clearly is best to not let the small stuff get out of the DC and into the shop. The filter costs less than $100.

I am convinced I need an air filter. However, I think the DC should have a cartridge filter. YMMV of course.

There is still some debate as to the .5 versus 1 micron threshold. I think Bill Pentz somewhat recently slipped over to the .5 micron side of the issue. I tend to agree. While I did NOT mention it in this thread, I have beaten this same drum over, and over, and over again… I wrote up a review of the HF 2HP DC called Great bang for the buck, but DON'T leave it stock! where I discuss the need for at least 1 micron filtration.

There is some confusion on the ratings as well. The Wynn 35A spun bond, is listed on the Wynn web site as being 99.995% efficient at 1.0 micron and above, yet it is rated at MERV 11, the paper blend is rated at 99.99 % efficient at 0.5 micron, and MERV10. It’s a matter of decimal places… In my conversation with Dick Wynn, he recommended I go with the Spun Bond, which is also the recommendation that I saw on Bill Pentz’ web site, and a HUGE part of the reason I went with it…

Please, please, please do NOT use this DC with the factory bag. It will literally simply pick the dust up, and spew it further out into your shop air making things worse… Upgrade the bag to a good cartridge filter (totally bypass ANY 2 micron or higher filter, at a minimum go with a 1 micron rated filter), and also install and use an ambient air cleaner to catch the stuff your dust hoods and dust collector will miss. (Even the guys with big 5 HP cyclones can’t capture everything…)

I agree with all of this.
