HF 2HP DC conversion to a canister at Wynn

[bolson]

I posted this on Woodnet and thought I'd give a heads up to my fellow BT3ers

http://www.forums.woodnet.net/ubbthr...lapsed&sb=5&o=

Basically for $63 you can get a super high performance canister filter for the HF DC that REALLY filters to 0.5 um. This is a heck of a deal to hae a canister set up for less that $250 (vs. about $500 for almost all other brands)

I have no affiliation with the company, just glad to get a good deal on a high performance DC

Cheers

this is not a harbor freight filter. It's a seperate filter from a company that specializes in filters for industrial uses.

There have been soooo many long discussions of the DC.
I bought the Grizzly canister filter replacement kit (Jet and PSI also makes one)
that I think is superior to the Wynn filter solution (altho more expensive).
Other people think the Grizzly .3 micron bags are the right solution.

Just a few of the Related discussions at BT3central:
The first one discusses the alternatives to the Wynn filter

Do search for combinations of HF, 2HP and DC on both archived and recent discussion threads.

Loring, other than the easy cleaning feature, what are your reasons for feeling that the Grizzly canister is superior to the Wynn canister? Also, what is involved to install the Grizzly canister on a HF DC? Thanks, Dave.

Hey, that's my dust collector and my shop!! I didn't think Rick was ready to release that webpage to the public yet as I still have to send him an updated picture....

Sorry for the messy shop in the pics!

They are great people to work with, and the filtration is truly awesome. We are going to measure efficiency and flow soon, and will update once it is done...

The arguments against the $63 Wynn canister filter and in favor of the Grizzly canister for $165:

The Wynn has much more pleats and surface area in a smaller diameter canister/cartridge. Depending upon which one you get (and there are several that have been recommended) you might get 10 to 20 times the filter area of 2 bags. The Wynn was designed more for dust particles than a mix of coarse chips and fine particles. Definately you want the no inner-screen version, and a presep will help eliminate the coarse. But if you have the 2HP 1200+ CFM units then the presep would have to be huge to slow the air enough to drop the chips. If you have a small presep (less than a 55-gal drum) and the chips are falling out then you are probably not maximizing the system air flow! Anyway the Wynn canister can plug up fast, I understand, with chips and can be hard to clean out.

The Grizz canister (and the similar Jet and PSI models) were designed specifically for a woodworking mix of fines and coarse - its has a bigger overall diameter (matches the center ring flange perfectly) and wider-spaced pleats, less area but overall still 6 times that of a bag. The wider pleats can be cleaned with a flapper arangement that all three units have built in. You may still want a presep to protect your impellor from nuts, bolts, screws, knots etc, but its not required to remove bigger fluffy chips and such.

Anyway thats the conclusions I reached to decide to buy the Grizz canister.

Those of you with 1 HP DCs, Jet now has a 14-inch canister/canister retrofit kit to fit the 1 HP units with 14" rings (and will fit the Grizz, PSI and Jet units of similar ratings).

As for mounting, its a piece of cake altho there are no instructions included with the griz kit as its intended as a replacement. You'll also need some plastic bags. I mentioned all the sources for these in a post once upon a time, too.

Loring, thanks for the quick reply. I've been playing back and forth mind games for a number of months now on how best to upgrade my DC. Due to space limitations, I don't have any presep system at all. Now you have me thinking if a canister filter is even a smart move because of the possibility of it being torn or even ruined by a flying wood chip. Time for a little more research I guess.

[bolson]

If you don't have a neutral vane I am positive you'll have to add this with any canister. If you don't you won't slow the air enough to drop the chips out and updraft large stuff into a cannister. If you look at any DC system designed with a canister (or that can be upgraded) they all have neutral vanes in the cyclone part to separate the stuff out by slowing the air. Basically you just need to get the cyclonic acion going in the downward direction to do this.

The whole idea is that the canister ONLY filters out fine particles. Traditional bag systems aren't designed to do this so they will clog up a canister.

This is a big problem for those that make their own cyclones, if they don't slow the air enough they end up clogging the filter because that is where the big stuff ends up

Once I get my put together I will post back with my experience as well.

I have almost the same setup, except mine is the 9L300BL mounted the other way up within the conical region of the green ring since it wouldn't fit under my low ceiling otherwise. A cylinder of window screen inside keeps anything but the smallest particles from contact with the filter. Tapping with a stick the outside metal grille while the DC is off causes most of the very small dust to fall into the bag, easing my concerns about the narrow folds of the cardridge: they are not a problem for me. Larger dust and chips should almost never contact even the protective screen, since the cyclone action of the lower bag prevents that unless it's overfull. I think the biggest system improvements are likely to result from smoother air flow: the inside of the green ring should not have bolts protruding, and the flex hose between blower and DC should be replaced by something smoother.

If the Grizzly is washable with water, much more durable, or shaped to be more convenient in your shop, those would be important considerations. Otherwise, if I were to spend more on a cartridge, I'd probably try the Wynn Env 28A140HOOL that I think is washable.

For $119 ($129 and $10 off coupons) for the HF DC, and $63 for the Wynn Env cartridge, this is quite a DC for under $200.

[Tom Miller]

My $0.02:

To get the best use out of a Wynn filter, you need to design your system so that nothing but fine dust gets into the canister. If you can't be sure of that, you may be money ahead by getting the 3x more expensive Grizzly canister. Or, if you have CFMs to burn, get a 2-3x less expensive Grizzly 0.3 micron bag. It all depends on your system.

Tom

I accidentally dropped a couple of 1/2" L x 1/2" Dia dowel cutoffs into the saw the other day with the DC off.
When I started the DC they immediately clanged off the impellor but dropped into the bag - as you would expect. The cyclonic action should push them to the outside of the ring (being denser) and they will drop down the outside. The lighter stuff goes to the middle and shoots up in the central air column. Those cutoffs did not hit the canister.

I have a neutral vane installed as Bolson said might be a good idea.

[bolson]

Loring,

Would you happen to have a picture of your neutral vane? I am deciding how to design this part of my system and would appreciate a peek at your solution.

Thanks for the help!

I have the Wynn filter. Not mounted as nicely as the one in the link but it works. This is my experince and responce to some of the concerns;
1)Clogging the filter: I have lost small pieces of wood and plastic into the DC multiple times. They always end up in the bag and the filter is clean upon inspection. Don't forget...that's what a DC is suppose to do...large particles down...small particles up. If you're DC is not doing that...then something is not right.

2) Airflow and filtration: I have measured the DC motor's amp and suction of my DC with the filter. My DC draws 2 more amps with filter (13 amps) compare to bags (10 ams). Static pressure goes up by about 1.5 (what's the unit? I have a mind block now) with the filter (8) and with bag (~6.5).
I don't know how to measure the loss of small particle...but mathematically, the surface area of the Wynn filter is larger than Jet's canister, and significantly more that the bag.

My conclusion: if you don't care how much money to spend...then get the Jet canister...it looks nicer. Wynn filter is a good alternative for the price. DON'T waste your money on bags.

[silverfox]

I have the Hf 2hp DC with the Jet canister and a metal garbage can presep. Works just fine & dandy. I understand now that the Grizzly is cheaper. I do agree with Mehran though...my Jet looks a lot nicer than the Wynn.
