Unbranded ring compressor, presumably 3 phase, at least 1 HP, and Fuji. From the stockroom of a closing industrial facility. The reason I say this is 3 phase, at least 1 HP, and Fuji is that I got a similar one from the same stockroom that was slightly smaller and was a 1HP, 3 phase Fuji that has a similar look. I'll try to test it soon and at least give some common voltages that it works at, but in the meantime, it looks to be in good working order.
