S Series Feature:
Effective Cooling fans design to highly reduce the compression temperature.
Durable cast iron crankshaft and pump - excellent wear-resistance.
User-friendly - easy operation and maintenance.
Various options for different application.

Two different type:
(1) ”P”type (pressure switch system )
The automatic pressure switch will stop and start the compressor according to air demand. It is normally recommended for intermittent operation and smaller compressor units.
(2) ”U”type (automatic unloader system)
The automatic unloading system allows for the control of loaded and unloaded compressor states through a range of pre-set pressure values. This system is recommended where the duty cycle exceeds 50%, and for all larger compressors units.
