Topic tags/keywords: dust collection shop vac adapters

So it’s time for me to do something about dust collection. I’m slowly putting together a plan for my shop which includes a dedicated DC, but in the meantime I will be using a shop vac with a Thien Separator. I’ve seen a lot of people using duct tape and what not to get the hoses to fit properly, but I feel there’s got to be a better way. The shop vac I have comes with a 1 1/4” hose, but has the fitting for the 2 1/2” hose. So I plan to use 2 1/2” hose from Grizzly for the project. My questions arise when I am looking into adapters. I’m sure they are simple, but I don’t want to order parts and have them not fit like I expect.

The hose I want to use: D4212
Question 1: Is this hose 2 1/2” ID? or is it 2 1/2” OD?

The adpater to connect it to the shop vac: W2046
Question 2: Will this properly adapt my shop vac to the hose? It looks like it, but I want to verify before I order.

This should all me to connect to my Table Saw’s 4” dust collection port: W1044
Question 3: would this provide me with a quick disconnect option, or do I have to hose clamp this together? I want to be able to put the dust collector away when I’m done with it, so hose clamps are not ideal for the connection at the tool. If not, is there a way to make it easy to connect/disconnect?

Good questions. I would e-mail Grizzly tech support and ask them. [email protected]

If you don’t already have one, I would put that money toward a respirator with replaceable P100 filter cartridges instead.

Even a big shop vac with a 6’ hose is only barely passable on a table saw, and trying to use a small shop vac with a 2-1/2”x10’ hose is probably an exercise in futility, especially if you plan on using a separator. If you want a bigger hose for your Shop Vac anyway (just to reduce clogs), go to any local store that sells Shop Vacs and buy the hose. Instead of spending money on the adapters, stack and cut up some plastic cups like the ones from the gas station, or make your own adapters from wood.

I’ll email Grizzly today. I figured a lot of people here had probably done this and would have some pretty good advice.

I already have a respirator. I’m just doing this to keep things cleaner until I can build a real shop with actual dust collection. The 2 1/2” hose and adapters from Grizzly comes to about half the cost of the shop-vac hose at Lowes, plus it’s an extra 4 feet long. So this is a really affordable way to keep the shop cleaner and also extend the capabilities of my shop vac.

In my experience, hose and pipe specs are usually ID.

I totally agree with Rob re: you don’t have enough machine there for a TS.
What kind of TS do you have? It might work for a compact or bench model.

would suggest looking into a wall mount dc’s. Grizzly and Rockler have one and they are rated at 650CFM.

For what you’re going to spend give it a try you’ve not much to lose.

I have a Grizzly Hybrid TS. Right now, it just fills up with dust which I have to shovel out every time I am done working. I’ve tried using the shop vac with the included 1 1/4” hose and it clogs those hose and filter almost instantly. So one way or another, I need to build a separator to make my shop vac more useful for cleanup. It’s going to be a $20-30 investment, so it’s far cheaper than a dust collector, even from Harbor Freight. And even if it can’t keep up with the TS, it’s still an improvement over what I’ve got. Like you say, I’ve not much to lose. Believe me, true dust collection is in my near future, but I need to have a shop set up first. Right now I tend to roll my tools out into the driveway where I have room to work. I’m in the process of designing a shop that will take up a portion of my garage, and that will undoubtedly include dust collection.

True dust collection is great, but I still rely on my shopvac/dust deputy setup for general cleanup and small, portable tool like a ROS. The DC handles most of the dust coming straight from the tools, but try your shopvac/cyclone setup with your TS. Be prepared for it not to work as well as you want it to, but at least you’ll have the smaller system for small cleanups once you get a true DC.

Thanks MrFid. That’s exactly how I’m looking at it.
