A while back after loosing a TT motor to probable static build during Lp dust removal, I switched to cans of compressed air. While not perfect they work far better than any other method I've tried. Treatment before and after playing has kept my Lp's much cleaner and I don't worry about static increasing dust attraction or taking out my motor or PSU.
So, to take it a step farther I'd like to either fill my own "spare tank" using my shop compressor or rent/refill a big cylinder of compressed air. I realize the need to filter out any oil/water vapor if I use a refillable "shop tank" or would go with "medical" grade compressed air (which contains no water/oil vapors) from a nearby supplier. I haven't priced a "supplier" cylinder as yet but I'm sure a larger cylinder would have a cheaper cost. If I use a refillable small tank using my compressor I could keep it in close to my TT area. I would also need a regulator valve so I could find a good PSI setting for a "just right" air pressure delivery.
Has anyone tried this before or gone this route? What am I leaving out or not considering?
