Well, for those who believe dry air is necessary for a MEDIA blaster, I have a few shocks for you. Then again, I can only lay hands on receipts for about 40 ton of media I've propelled at various surfaces.
The air tools in my shop and service truck never complained about a little moisture either. Air tool oil pretty much solves that problem.
If and when you're ready to accept the reality that water cannot be efficiently removed from a compressed air stream completely, and that even refridgerated and descicant filters can only remove so much moisture from compressed air you might be ready to procede. Till then, keep believing salesmen and AlGore I repealed the laws of Physices Web Sites, and pissin money down the drain.
Hell, i ought to be selling Franzinator plans for $19.95 emailed to your computer, and Air Polisher plans for $29.95.
