compressed air?

[JW999]

Hi guys, I recently purchased a used RT valve for my 68 automag. I was wondering what the best way to hook up compressed air to my marker would be? If i get a preset tank should i get a high pressure or a low pressure one? Do I need to run a regulator, if so any suggestions on what type? also what is the suggested input pressure to the valve?
Thanks

If you get a pre-set, you'll want high pressure. You don't need a reg, the valve already has one built in. If you put a reg on, you will starve the valve of air. Not positive, but I think input is somewhere around 700+?

Most presets are around 850 (the high pressure ones)

That's the one you want. The mag wants a MINIMUM of 600psi into it. No other regulators or anything needed.
