The compressor came with a auto drain. Heres the deal . I found this compresasor on craigslist just north of me. It was brand new. The man had bought it for his shop but passed away before he could install it. His son wanted it gone. It had the auto drain and magnectic starter box and a gallon of oil with it. all for $1100. So far so good. it runs quiet and pumps up fast.
