Hi i'm relatively new to air compressors and need one to power one of my semi-automatic machines. I recently bought a small 100psi oil-free air compressor from Atlas Copco and am trying to figure out what type of male beyonet will fit the female coupling on the compressor. Atlas Copco THEMSELVES do not know and have given me several wrong answers to the point where im very close to returning the machine because of their incompetence and lack of basic knowledge. It is not a UK or EU standard bayonet so i have no idea what it could be. Thanks for all the help in advance.
