That appears to be the Tuxing compressor. There is a bunch of information on AGN under the compressor section. Look up the review and in depth upgrades done by many members. Centercut did an outstanding series on that machine. Several companies have rebranded them with their own name. I believe Hatsan is one. They are a Chinese product and have generally good marks. go here on AGN Air Tanks, Pumps, & Compressors
@coldair It came from an EBAY seller. It is the low end model. He had it for $450. freight paid. I made an offer and they took it!! I had a lot of trouble with it at first, but it has been working sense. 4 hours on it. Like the ad Rico has linked above only mine don't even have the adjustable pressure gauge LOL.
