After compleating the compressor and dryer connections it was time to pressurize the system.
We first blew out the lines with 50 psi to clear out any small aluminum chips left in the system. Installed the QD's and drip legs at the drops and introduced 50 psi to pressurize and leak check. So far so good....Then went to 70 psi and boom!,I had a coupling failure (so I thought). Turns out I had not tighten this coupling tight enough. Bled the system down and reinstalled and tightened it up. I decided to check all the fittings as this system took me about a month to install due to the nature of my main career. I found a few fittings to snug up.
I waited about five minutes between increasing more pressure and eventually got to 120 psi and closed the main ball valve at compressor.
This system is large at 350' and supplies a new construction 40'X80". The system is a loop system consisting of 1" FastPipe Aluminum with teflon compression fittings (rated at 190psi). At the farthest point of the compressor will be a CNC 60" x 110" plasma table requiring ample air during long continuous cuts. I could not afford pressure drops as this would complicate cutting matters. I found a large Pressure gauge to use as a "systems monitor" and mounted it to the wall for quick reference while cutting. As of this morning it still is at 120 psi.
I wanted to share and answer any question for those who might consider using this product. I know many folks have used the Rapidair semi rigid but found limited infomation on the Fastpipe system.
