My cascade setup is working out so much better than I thought it would. The tank on the left is a 74 cu ft tank , and on the right is a 98 cu ft. Joining them together is an Air Tanks Plus T-Man junction. I normally use the smaller tank for the initial fill , then top off with the 98 ct ft tank. I fill my 2 AGT guns to 300 bar and this has cut back on the need to top off the air tanks. I'm fortunate that I have a ready supply of air and have found that this makes compressor top offs less frequent. If you have the opportunity to get a setup like this , don't hesitate. It is a real time saver. The smaller tank gets refilled about three times before the big ' un. That's my story and I'm sticking with it.
