Duh, head slap, Oh $h1t, YER RITE Harold, I hadn't thought of that. I've read the warnings about flammable materials through it, but I hadn't realized that rubbing alcohol is flammable. I mean, I knew it, but some how or other I hadn't connected the dots. It seems so benign. I mean, think about it, it could cause a flash fire wherever the fumes are. Wow, thanks bunches & bunches for the warning. I owe ya a case of beer or somptin.
It could be using outside air to cool it, but I don't think so. It's too bad Sears has discontinued it, because it can't be viewed on line. But it is a combination wet/dry, quiet, blower, and pump-out model, which is funny looking, kinda like a red & black R2D2 from Star Wars. The Exhaust air exits from several different areas, which at least partially contributes to its quietness. (And it definitely is quieter that most shop vacs) It also has a 2-1/2" hole in the rear w/ a screw on cap that can be removed for use as a blower. It was the quiet & the pump-out features that caused me to buy it. The "Shop Vac" brand vac listed below describe its features fairly well:
Boy, I'll say some good came out of this, John
