Great setup. I finished running mine in 3/4 black pipe about 9 months ago. It is great to finally have enough air in the shop. My next step is a line back to the shed were I have a vise stuck in the ground for the really dirty work.
Something you may want to consider instead of a frazanator is a simple after cooler plumbed in before the tank. I just picked one up from Zoro for ~$135 (w/ 30% off). Good for 400psi and 25cfm I think. I'm going to mount it opposite the flywheel on my Quincy 325 so it gets airflow without adding a second fan. I know a few people here have used transmission coolers with electric fans.
I cant find it at Zoro do you have an item number?
