Scott, no I use a microwave.
I have a small 15hp screw compressor and dryer. It sits on a 80 gallon tank, and the system is about another 30 gallons of a capacity. The downdraft table has a storage tank for the pulse cleaning, but I'm not sure how big that is.
Point is, it takes almost 5hp of compressor to produce the 15cfm at 90 psi that sander requires. Pneumatics while useful, are a horrible waste of energy in terms of efficiency. Factor in compressor maintenance, filter costs, electricity, it's a big expenditure to do not much.
No, not all of my sanders are hooked to a single vacuum, one has no vacuum as it is operated on the downdraft table. One sits in a box for jobsite use and as a spare should the need arise. It gets used occasionally with the install vacuum in the shop. The other three are hooked to their own oneida dust cobra vacs, and sensor switches, the vac also services the chop saws on those benches. See picture.
The coax hose they sell is a kick in the tool pouch, but it's nice to have only one thing getting tangled. Don't wrap the cord where it comes out of the sander around the hose tightly, it will eventually fail and your options are: fix the stupid thing, or spend an obnoxious amount of money on another. There might be cords of the correct length available too. That I do not know. Then it'd be a cheap easy repair. Take it apart, and shake a new cord in the hole.
They're solid units. I still use a dynabrade from time to time for certain things, but not much. Let us know how you like or hate it.
