These are really small little Air compressors made by Cornelius or Stewart Warner. This example with the shock mount try attached weighs 8 pounds 8 ounces only. P/N 2830400-3 My research shows that this was used on B-52 stratofortress bombers and had something to do with a waveguide assembly. I’m not 100 percent positive on the PSI output or the CFM of this particular air compressor. These are in untested condition as I don’t have a 27 volt power source. These run off a DC motor that is 27 – 28 volts Pretty neat little air compressor!
