Yanmar SC-N Series
The SC-N Series covers eleven displacement sizes, from the compact SC5N at 4.8 kW up to the SC75N at 78 kW. Models SC5N through SC12.5N run at 1200 rpm; SC25N through SC75N run at 900 rpm. All units are freshwater-cooled two-stage compressors rated to a maximum working pressure of 2.94 MPa (30 kgf/cm²), with the SC25N alone using a single-cylinder stepped-piston layout instead of the twin-cylinder arrangement used across the rest of the series.
