The S series comes in 3 variations:
 
S30: 3hp ISO30 220V 18,000rpm Steel Bearings
S30C: 3hp ISO30 220V 24,000rpm Ceramic Bearings
S30F: 3hp ISO30 220V 12,000rpm Steel Bearings (4-pole motor, for higher torque at lower rpm*)
 
*For applcations requiring higher low end torque, it is recommended to pair the S series with the Hitachi WJ200 VFD.  This sensorless vector VFD provides much more robust low end rpm performance.
