HELP!!! My head is about to explode from all the info and choices regarding dust control.
I am looking at the Grizzly G0703HEP, and an air filtration unit.Any thoughts and recommendations would be helpful, especially if anyone has this system.I have a 24×24 garage/shop.
Thanks.

You’ll get as many suggestion as there are people with different systems. Delta, Grizzly, Jet, Laguna, Rikon, Oneida, Harborfreight and the list goes on. Pick your poison.

Have you considered the Jet? This vendor has free shipping. http://www.cpojettools.com/jet-717515-115v-1-5-hp-1ph-cyclone-dust-collector/jetn717515,default,pd.html?start=1&cgid=jet-dust-collectors

I have a HF with a Wynn Environmental filter. Works great. I also built a separator with a Thien baffle. Total outlay was <$300.

That Jet looks nice. The big reason I like the Grizzly is for the HEPA filter, if one could be added to Jet that might be in my future.

Today I think it will cost you at least $400 to do the same.

I’m not convinced that the added hepa filter is really needed. I imagine that hepa filter is expensive to replace. Have you checked on the filer replacement cost?

Edit: Holly cow it’s $200 just for the hepa filer.

The grizzly cyclones are very high priced on an hp basis compared to the other cyclone options like oneida, penn state, clearvue.
775cfm is very good for that hp rating but in the overall scheme of dust collection, it’s pretty low.

I think the main question you have to ask yourself is, what do you really want? Do you want to collect the finest particles, or just the chips so you don’t have to sweep your floor as much? If you just want to keep your floors clean, then anything from the Harbor Freight on up will work.

If you’re looking at fine filtration, you’ll need 3hp with 6” ducting all the way to your machine, minimum.

Not a big shop operation, won’t have any duct work just manually hook up to tool when using it

Yes the HEPA is $$ but I would think it would last a good long time. I just want to collect as much of the fine dust as possible.

If you haven’t already, be sure to visit Bill Pentz’s web site concerning dust collection.

http://billpentz.com/woodworking/cyclone/

Bill Pentz has a lot of sobering information about health effects of dust. He became an expert as a result of addressing his own health issues related to dust.

While I have yet to take the plunge (still using a shop vac for DC), it seems a pretty common sequence people go through is shop vac, HF DC, some intermediate DC, finally bite the bullet and get a 3HP to 5 HP system. Then regret not just doing it right the first time.

I’ve studied this a bit, and my only reason for not going big on this, is I don’t yet know how much woodworking I will ultimately be doing.

I’ve mostly been using a table saw and the shop vac does okay getting the bulk of the dust, especially when I can use the overarm DC extension and the blade guard. I use a Jet room filter. Air stays clear, but noticeable dust settles around the shop.

I use a respirator as much as I can. Always regret making even a few cuts without it. Just yesterday, I made maybe six 4” crosscuts through 3/4” material, I figured I didn’t need to bother putting on the respirator. Noticed a bit of a cough last evening.

My take, DC and health effects of dust should be taken seriously and therefore err on the side of too much, not too little. I’m not sure there really is such a thing as too much DC, other than more $$$ than you would like to spend.

Do you work with the garage door open or closed? I think you can get away with the none HEPA version if open most of the time, and pick up a 3M respirator.

Watch yourself getting nudged into 2 HP, 3 HP, and 5 HP systems by the end as you read more about dust collection.

I do seem to read a common consensus that people eventually upgrade to some sort of duct work bc they get tired of rolling around the DC.

Few portable units to look at:
Shop Fox W1823 $820
Grizzly G0703 or G0703P $850 (P version is on sale for $755 + $80 shipping, and another $100 to upgrade to 220v)
Oneida Molded Mini Gorilla $980 (+$155 shipping)
Dust Gorilla Portable $1,545-$1,745 (+$300-400 shipping)

Also single stages with dust deputy for 2 stage.

Curious what you pick, I’ve been unable to make a choice for a year now, stick to a respirator, shop vac, and broom.

Oosik, I use OGD system(open garage door) all the time but would like to do a little more out there in the colder months. I guess I just have more pondering to do.

You think you’ve got issues now, wait until you start to buy fittings. There is no agreement on ID or OD listings in product description, and 4” PVC has a different wall thickness than the black plastic fittings. Luckily fittings aren’t all that expensive – so over buy – you’ll need them eventually.

Slip-fit fittings aren’t. My system didn’t work right until I slit the ends into 1/4’s and used hose clamps to get an airtight fit.

Buy metal blast gates. Buy a .5 micron bag.

If you have a planer you need 1000cfm or better, a 2-1/2” line won’t work, you’ll need a 4”

There’s no way you can get 1000cfm through a 4” hose. You’re going to average 400 tops.
