Question

Hey, I have a few of my own markers and want to start doing cleaning and tune ups ect but I cant figure out a home setup for filling the tanks i currently only have 60 gal dewalt that will only pressurize to 140psi. How do I get them to 1500 or 3k? Any help would be appreciated. Especially if you have links to stuff I can buy to make it happen and start researching options.
