Air/water separator for Nash liquid ring air compressor. This is the size used for Nash models 1251/1253/1256, 50 HP through 100 HP. Overall dimensions 23" long, 20" high, 10" wide. Inlet is 2" NPT, drain outlet is 1 1/2" NPT.
Unit is sound, internal stainless steel float seat assembly is in good shape. The unit drains out and seals well when water is not present.
I sandblasted inside and out to remove most of the lime deposits. Little corrosion, separator should be good for many years of service.
