Regular air compressors also dispense moist air.
You could buy one that can fill 4000 psi for example but the air would be contaminated with dust, moisture and sometimes oil.
That's why proper air cylinder fill stations cost so much is because it dispenses dry air.
Edit: I do scuba dive(sport) so I own multiple tanks and I use my one scuba tank to fill my out of hydro'd tank at home (people are gonna flip on me for that one)
I bought the said adapter mentioned above for $16(with shipping) on ebay. Very good deal I suggest you do that when you wanna shoot at home.
Scuba tanks are also $10 to fill at my scuba store.
