Topic tags/keywords: dust collector harbor freight thien baffle dust deputy

Yesterday I went down to Harbor Freight to check out the dust collector that they were running for $139. Based on the other good reviews I’ve seen on here I decided to give it a shot. I’ve got it home, assembled, and I’ve ‘dry run’ it a bit and it seems like it is going to be good.

That being said- I know that the filter bag is inadequate and I’m trying to figure out what’s next.

It appears everyone says the Wynn cartridge is the way to go- and I’m good with that but I’m confused about whether I’ll then need a ‘mod’ for it to fit. I’ve seen it written that no mod is needed- but when I go to the web site they have the write up on doing a mod. So- will I need to do some modifications to make it work or not?

Also- I take it from the forums that it’s good to add a 2 stage cyclone / separator. Would that be a dust deputy? It seems like that would just be too small for this application. It doesn’t look like the black trash can lid cyclones are quite as good? I’ve seen the write ups on the Thien baffles as well but I’m not sure I want to take that on at this point. I’d appreciate any input that others may be able to share?

I have three of the Hf units but run mine outside so the filters are not necessary.

If their website specifically says you’ll need a mod for a HF DC, they probably know what they’re talking about don’t you think? – lol

You probably don’t need a cyclone although they’re supposed to be better. Get your system running and see if you really want/need the cyclone. DC systems are often a work-in-progress. I’m still tweaking mine after seven years. – lol

Sewkerf- OK I admit- I was being a little bit lazy asking for other peoples experience but IMO the Wynn website looses a little bit of credibility since it has the appearance of an ‘artifact’ of the early 90s. (But hey- they are woodworking folks, not web geeks, right?) :)

Never the less you made me feel guilty- so after going back and looking again- the write up is for the 9E300BL – which seems to be different than the one that is actually recommended for the HF DC ( I guess that is what is throwing me- why the 9E300BL conversion if the 35A series work just fine?

Plug-and-play on mine.

No mods required.

My HF 2HP DC is only about 6mos old. Ditto my Wynn 35 cartridge.

Good setup. Very happy with it!

dmorgan -
I’m not familiar with those specific components (I have the Jet 1100cfm DC with a Dust Dog cartridge filter), but the unit pictured in the link looks like my DC with a different paint job.

Measure the diameter of your DC and take a look at a Dust Dog filter. If the diameters are the same, a Dust Dog might pop right on and you’re in business.

If you really want to use the Wynn filter, the link clearly shows the process for making a mod. You just may need to do a little “fit and fiddle” work to make it work for your parts.

You’re well on the way to over-thinking the project. I just put good bags on mine and quit. Very pleased with the results.
There have been some problems with the on-off switch.

I’ve had the HF 97869 2HP DC and Wynn filter about a year now, no modification to the DC to get the Wynn to fit, Just take the hoop and bags off, drop the canister in place, set the turnbuckles in place, tighten, then install the lower bag. Easy as pie…Some other 1.5 – 2HP dust collectors need mods like donuts to fit, but the HF DC is a direct bolt on affair. Wynn designed it that way.

I would recommend after the filter, you add either a Neutral Vane, or better yet, a Thien separator, THAT is some shop building, but not much. Mine was done with a 55 gallon drum, some all thread, PVC fittings, nuts, washers, and tempered hardboard, not exactly a Clear Vue, but excellent separation…

Thanks all for your feedback. I’m going to order the Wynn cartridge as soon as I can get them on the phone. :)

Then I’ll figure out the Thien baffle / pre-separator piece.

Have your say...
