i would like to purchase a jet 16-32 drum sander,but only have one dedicated 20 amp outlet which i use for my 1 1/2 hp dust collector…i would like to know if anyone has used their 16-32 with a shop vac or have they plugged their sander into 20 amp outlet with lights also on the circuit…i know what the correct answer is two 20 amp outlets but my panel box is full and i do not want to add a sub panel just for this sander…any advice would be greatly appreciated

I think you are pushing your luck to try to keep up with the dust coming out of that thing with a shop vac. If you do try it, be sure to add some sort of pre-separation like a Dust Deputy, otherwise your shop vac filter will be plugged within a couple minutes.

As far as running this on the circuit with lights, I wouldn’t go there either. The 16-32 is rated at 14 amps, and for each 100W of lighting you will add about .9 amps to the circuit. I believe that the guideline for loading a circuit is to stay at 80% of the maximum load, or 16amps in your case. So, if you have 200 watts of lighting or less, you are within spec.

I would add the subpanel. Its a quick and inexpensive project, and chances are if you need another slot now, you will need one another one in the future.

You could add another circuit by useing a piggy back breaker in the existing box especially if you have ITE ,GE. Crouse Hinds breaker box.

Shop vac will work fine. The noise is annoying though and
drum sanding is a tedious process.

I had a 22/44 and I used a vacuum for the dust. You can’t take
off much material in a pass at all so the amount of dust is
not that much, though build-up will become a problem quickly
without some sort of suction.

loren..you used a shop vac with a 22-44,so it is possible but not a good choice?? what do u mean by “some sort of suction”... a dust deputy like pmayer suggests?..i already have 10-20 sander so i know how to just take very small passes at atime….thanks for ur input

I use my 16-32 with a shopvac (Fein) and Dust Deputy all the time. Works great. The vac and sander are plugged into different circuits of course.

Well, it’s mostly just annoying and fatiguing to listen to.

I used a cheap little one-gallon stinger vacuum on the sander. The
short hose probably helped it work well for this.

The Dust Deputy or similar (you can build a Thein separator yourself) is essential to protect your shopvac’s filter from getting clogged and keep the suction high. Hopefully you have a good filter (at least 1 micron, HEPA would be even better) in your shopvac – otherwise you’re going to be getting the ultra-fines spit right back at you, separator or not.

You will also need a few dust collection fittings to connect your shopvac to the 16-32. The new 16-32s have a 4” dust port. I just duct taped a 4-2.5” reducer to the port…not the most elegant solution but it works. I’ve never tried collecting with smaller than 2.5” shopvac hose, so not sure if there would be a performance drop in that case.

I have jet 16-32 sander. I also have 2 20 amp services in my garage. I still run my HF dust collector and drum sander on the same line. It hasn’t ever tripped the circuit, I start the dust collector first than turn on the drum sander. The lights in the garage run on a seperate 15amp service. SO the dust collector and drum sander are the only things running on that 20amp service. You wrote that you don’t want to add a new panel, but what happens when you buy a new tool and need the room, I would fine a way to get a new panel, good luck

I have the Performax, and I use my Fien shop vac with it. The vac does OK, not great but the wall breaker on my 20 a circut does trip occasionally, not often. I trip the breaker on the sander way more often

Even though shop vac might capture the bulk of the dust, I would hesitate to use this as a permanent solution as it is likely leaving a lot of the fine powdery dust behind. Typically you will see the CFM requirements for a 12+” drum sander listed in the 500-600 range. Granted, there is a lot of debate on what the right number is, but I doubt that the right number is below 300 or even 400. For a reference point my garden variety 5HP shop vac with 2.5” hose pulls a whopping 78 CFM and a bit less than that when run through a dust deputy (I haven’t actually measured this, but there must be some negligible drop).

With respect to the 16-32 It helps that this machine is only a 1.5 HP unit, so you will not overwhelm the shop vac like a 5 HP unit would. I have an 18” drum sander with a 5HP motor and I need every bit of the 850 CFM that I draw to keep the air clear. My shop vac wouldn’t stand a chance.

So, it no doubt will save you some sweeping, and help with surface quality, but I suspect that you will have a hard time keeping fine dust out of your lungs with it, especially if you are sanding a piece that spans the entire width of the machine. I would wear a good dust mask for sure.

I have a performax 16-32 and I could not imagine trying to use it with a shop vac. I have a big shop vac and it has tons of suction power but it just doesn’t seem like it would have sufficient CFMs to capture all the dust. Another thing to keep in mind is that if you are taking very light passes then the sander is probably not consuming the full rated current load. As motor resistance increases so does current draw, and from my experience the motor does not have much load if you are taking light passes. This may explain why you could run it and a DC on the same circuit.

I have used my 16-32 w my ridgid shop vac. It worksbut clogs very quick. I have 1hp jet dc that worked slightly better.
