I have a downdraft table that I had built myself and it does a great job but the only drawback is the dust port on the ROS itself. Sometimes, depending on where I’m sanding, dust can escape, especially if there’s a breeze going through the shop. I was thinking of getting the Rigid Buckethead and just mounting it directly to the side of the table so the dust from the sander gets directed directly into the table.

Another option would be to just set a small, complete unit with no filter inside the filter box of the downdraft table.

Are there any other shop vac heads that can be easily mounted to the side of the table and just blow into it?
I assume I wouldn’t need something with the most suction capacity for something like this but I’m open to other ideas.

Personally I have a fein II vac that I use for sanding and other cleanup. It is quiet, powerful, has a auto “on” switched outlet, does not spew dust out the exhaust and it is hepa approved. They are expensive, but I thought it was well worth the cost even after several years of hard use.

I currently do not have down draft table, but plan to make one yet as the dust pickup using the vac alone is incomplete. My thoughts are to hook up my 4” DC line to the downdraft table and have a 2” branch off of it to hook directly into the ROS. This way I should not need to use the vac anymore for sanding smaller sized projects.

My downdraft is a self contained unit driven by an hvac blower. I would put the hose direct to the cabinet but the way the blower works, it doesn’t provide much in terms of suction so nothing would be pulled through the hose.
That’s why I’m thinking the only way to do it would be to use a shop vac head that’s directed into the cabinet so the filters inside can deal with it.

The only thing I don’t like about it, is the noise. The downdraft table is very quiet. You barely hear the hum from the blowers.

Depending on what kind of ROS you have … I think it would be pretty easy to make something from either plastic or perhaps thin aluminum sheeting to direct the ROS exhaust DOWN so it shoots the dust right into your down draft. Or maybe a piece of tubing that fits the exhaust?

Here’s a quick (very crude) idea showing what I’m thinking of

For under $100 the Craftsman XPS 12 Gallon is the most powerful on the market. I have one and I love it. It is even more powerful than the XPS 16 gallon.

I have used shop vacs for dust collection for a downdraft table and for a scroll saw and found that extended running of a shop vac will kill it. I killed two used and one new one using it this way. Shop vacs are made to run for shorter periods of time I guess.

They really don’t pull enough air (IMHO) for a downdraft table anyway. A DC would be better suited for the job.

I’m wondering if I just run the hose from the ROS to the cabinet if I’ll be fine.
Don’t the sanders generally have some kind of airflow to move the dust through the hose even without a vac?

The cabinet itself will have minimal suction through the hose.

Thanks, I’m thinking something like that is going to work best. Sometimes the simplest things are the best.
