Gas booster HPA air pump fill station. This is new and only used twice. It is 6000 psi. Gauge is oil filled. If you are interested please call 540-305-1109. If you would like to make sure it works you would be welcome to bring your equipment and test it. There is one on eBay for $600 but its only 5000psi. I am asking $600 or best offer. Please no ridiculous offers. Please respond for more pictures. I am located in Front Royal Via approx 1hour from Sterling Via.
