Not sure what brand these are but they were bought new last November. They have minor dings and scratches, 120psi max, 152 decibels. They are very loud. Come with the 7 gallon air tank. Had it set up to be easily removable take in and out of the bed of my truck but can be set up different. Doesn't come with a compressor, never used one with it, just filled it up before I left the house. Asking $300 or best offer, text for more pictures. prefer text or email
