Well after being held up in customs for a couple of weeks my booster arrived compete and well packaged. Any time I emailed Altaros I received a prompt reply and they were quick to supply the info needed to clear customs sometimes more than once. I installed mine so that I could compress from a nitrogen source and after doing some plumbing to do that it is now up and running. I did make a aftercooler for my compressor to removed the water and after about a hour of running not a drop of water came out of the booster. Overall I am very happy with it the only issue is the set point needle will move during operation but a piece of tape will cure that.
