Does anyone know if it’s possible to retro fit my Delta AP400 with a larger motor than the original 1 h.p.? I bought this unit off Craigslist. The problem is that the suction is low, so low that it hardly vacuums the dust from my table saw. Thanks! Joe

From doing similar research not too long ago I’m not sure that the AP400 air speed is fast enough to suck DUST and is more appropriate for SHAVINGS and CHIPS. that said – make sure that your TS is sealed properly for air, and that it doesnt have too many openings which will make the DC lost it’s suction capabilities from where you want it to work best – the table top. Also make sure you use a Zero-Clearance Insert for your TS – this will highly improve dust from collecting on the Table top, and make it easier for the DC to get that dust from under the table.

how is the AP400 with collecting chips and larger pieces? (just curious if it’s something to do with the actual unit, or if it’s the lose of suction only with the dust on the TS)

for more info you might wanna check out Bill Pentz website that has a good amount of information.

Bill, Thanks for your help. I believe the main problem will be the TS having too many leaks around the bottom. I’ll work on that and see what happens. Skeez, thanks for your advice.

Joe, I have the AP 400 as well and noticed the suction is mediocre in my opinion. Mine is a simple install with about a 15’ run with 5 blast gate. Like Skeez said, I only open one at a time.

I don’t get a very good draw at my lathe, which is the first tool inline and only about 5’ from the unit. Suction is almost non-existent on my Ridgid spindle sander and I’m sure that’s not helped by the 2 1/2” port on the sander.

I turn a lot of acrylics and they tend to make ribbons as opposed to chips when turning. I noticed suction was worse than normal and after checking every hose and gate I went to the impeller – it held a huge birds nest of acrylic ribbon as well as a couple strips of sandpaper that got away from me at the lathe.

I know this doesn’t answer your question but hopefully gives more insight into other experience with the AP400.

Tim, thanks for your insight. I’ll probably look into buiying a more powerful unit, until then this one will have to work. I bought this off craigslist for $80 and the guy threw in a bunch of metal blast gates and extra lengths of tubing. Those parts will come in handy if I upgrade later. He also gave me an excellent book called “Controlling Dust in the Workshop” by Rick Peters. After reading it, I’ve become more concerned with trying to capture the smaller micron dust particles. I believe the bags with this unit only go down to 30-microns. But hey, live and learn, right?

Tim, I had a thought about your acrylic ribbon clogging the impeller. You could build a pre-separator to collect it before it gets to the impeller. In the book I mentioned there are simple fixes, like using a trash can and PVC pipe. The heavier ribbons would drop into the can prior to the impeller. It would probably save you time, too, because your bag wouldn’t fill up as fast and the trash can is easier to empty.
