Compressor storage tank

Check out Home Depot or AutoZone, or any other big auto parts store. I have seen compressed air storage tanks for about fifty bucks, that are safety rated. They are made for refilling a flat tire (or some similar situation) where a compressor can't be taken. If the price seems a bit much, just remember the safety thing. Be sure not to exceed the pressure rating of the tank. You would need to put the regulator and guage on the tank itself, with the compressor running straight to the tank. ONE THING I WOULDN"T DO! DON'T try using a tank that was previously used to contain something else! I have heard of people trying to use old Freon bottles for this, but they are NOT designed to be refilled by a consumer. When they are returned to the source for refilling they go through a special testing procedure to make sure they are safe. Spend the money and have some peace of mind. Nonetheless, they are out there. Hope this helps. Stinger

I made a storage tank from a recently emptied Coleman propane bottle. It was originally rated at about 75 PSI. I purchased the appropriate brass fittings and pressure hose conntectors at Home Depot, connected everything,and plan only to keep about 30PSI max in the tank. I've used it successfully without mishap for nearly a year. I have since made a bracket with aluminum strapping and wooden dowels to attach it directly to the compressor for a more compact unit. I'll try to post a pic in the near future. Stinger is correct in regard to setup protols. I've done exactly what he has stated regarding my setup. On the other hand, there are compressor/holding tank units commercially available that, while they aren't dirt cheap, they are affordable and reliable. Your choice :) - Ed

Thanks for the input

I have a little blue CH storage tank for airing tires, etc.
I attached a quick-collar to it and a regulator/moisture trap.

I can air the tank to about 120 PSI from the big compressor in my garage and I can get about one paint cup and a clean-up out of it before I have to re-fill. Works great because on larger jobs, I just take the quick release on the regulator/MT down to my compressor and paint in my garage. Good set-up and free re-fills!!
