I believe it is Sullivan 185 compressor. It Runs good doesn’t leak, I have changed all the fluids and new filters. I’ve used it for personal soda blasting But have smaller unit that easier to move around this compressor is ready to go u can test it out before you buy it. I’m located in McKinney Texas. If you’re interested I can send you videos of it running or do you have any more questions or concerns or need more pictures I’ll do my best to get answers. Thanks. Asking 3600.
