Dust Collector Retrofit Grizzly

GaryK posted a blog about trying to get his dust collector modified with a canister filter.

I was thinking about doing the same, and after his post I checked into the requirements.

This is my existing setup.

It is a Grizzly dust collector with a 2 HP motor. The metal ring in the middle measured 19” across.

I called Grizzly and they have an item called an additional cannister. Not sure if that means you can stack one on top of another or what. But I asked and they said that it would fit my dust collector.

I ordered it. Everything was back ordered with the exception of the plastic bag. Go Figure.

This week this is what I got.

The plastic bag in one shipment. A clamp for the bag in another shipment and the Dust cannister in a third shipment.

The canister cost $150.00 shipping was about 50.00 because of the oversize.

So I took everything apart.

There were no directions because this is an additional canister and I guess that you could look at your old one to see how it fit. So I guessed.

This is what I got in the packages.

The inside of the canister. Note the foam around the inside of the ring.

The canister box also contained two strips of foam rubber.

You can see that the ring has a deeper impression where the band clamp would fit. So I put the smaller piece of form there.

I them put the larger piece over the top of the smaller one and covered more of the ring.

I then set the canister down on top of the modified (with foam) ring. The canister also has a piece of foam already installed in the ring. It fits tight to the metal ring.

The plastic bag was a little oversize (Little!!) So Odie suggested in GaryK’s blog that I visit Big Blue and buy contractor bags. I did that this morning. This bag here is the Grizzly bag.

So I turned it on. The suction increased a lot. So I cleaned up a little from the previous saw cutting.

People also ask if the Cyclone works well. I bought this one on ebay and I screwed it to the metal lid on a trash can.

The picture of the can is what i picked up in 5 minutes around the shop. The shinny spot in the middle is where I rubbed my finger to see how deep it was. It was about 1/2” deep.

This is what was in the bag. Maybe 1/2 a teaspoon.

I’m happy so far and I hope that the dust in the air is cut out.

Nice setup! I did the same with the canister but used the small piece of foam under the clamp for the bag. Actually went on Grizzly’s website and found installation directions. At least they didn’t sell you the extra support that is not needed. DAMHIK!! Can you tell me whether the cyclone is available at an ebay store or did you buy it from an individual?

I noticed increased suction by adding a retro-fit 1 micron filter to my dust collector too. You will notice much cleaner air in the shop. It does not have that initial “puff” of dust when you turn it on.

I think the proof of performance comes at night when I go to bed. I used to cough up brown goo from my lungs after using my sanding machine. I did that a few times and realized I needed to have better filtration on the DC. The old set up was killing me.

The current item on ebay is here

I looked for “dust cyclone” in search. This is the same guy that I bought it from. $189.00 and he is in New York State.

That’s really going to help Karson.
I would suggest you build an ambient air filter too so you can to grab the fines out of the air.
I run mine continously 4 hours a day and it seems to collect a tome of powder.

I have learned that I need to turn the handle on the canister at least once a day to keep it clear.

You can tell it needs it when the plastic bag is very rigid when you press on the side with a finger.

Good deal Karson!

Thanks for the comments I’m looking for great results.

Bob I have a Jet ambient air filter, mounted on the wall.

I have the G0548 dust collector by Grizzly which is essencially what you have now. Just a note of caution for operation with the canister filter. When the dust collector runs the contents of the bottom bag swirls around in the bag. When the bag gets about 1/3 full of collected dust, the swrilling collected dust starts to migrate up into the filter canister. When the canister filter becomes plugged due to the heavy saw dust it blows off the mounting ring and dust goes everywhere. Empty the bag when at 25% full and shop vacuum the canister filter out. The dust wiper arm is not very effective as it cleans about 50 percent of the canister filter. I would like to see a better dust separator design.

The link for the cyclone no longer works, but I found this link:

It looks like the same cyclone which looks jut like this one:

How does one know if a cyclone is ” a good cyclone ” or not?

I’d guess the amount of dust that ends up in the bag..

Most of mine is because I don’t enpty the can as aften as I should and the bag becomes the overflow.

When I turn the paddle on the dust filter I watch the bag to see how much dust is shaken loose and it seems very small so the filter is not getting a lot of dust going up to it.

How does this cyclone compare to a Thien baffle?
