The BZ99S was born from the commercial world. Unlike many home machines that are scaled down from commercial designs, the BZ99S was a commercial machine squeezed into a slightly smaller chassis. Inside, you won’t find plastic tubing or vibratory pumps (except in very late models). You will find a copper boiler, brass fittings, and an industrial-grade rotary pump (in most early versions) that purrs rather than rattles.
