I apologize if this is the wrong spot to put this, but i was hoping to get some info on a compressor i recently purchased. I wanted to see what it's worth so i can decide whether to keep it and use it or sell it. It's an Atlas Copco 5hp three phase, 230/460V, 120gal. I didn't find much through googling except new Atlas Copco models, and of course that's not much to go by for third-party sales. I snapped a couple pics of it including the tag. Thanks!
