Direct drive for plant air
The KRSD is Kaishan's single-stage, direct-drive rotary screw line for production plants, from 15 to 200 HP. With no belts between motor and airend, there is no belt loss or belt maintenance, and the SKK airend with its asymmetric 5/6 rotor profile delivers up to 902 CFM at 125 PSI.
Choose fixed speed for steady, full-load demand, or variable speed to match output to the air you actually use. The 15 and 20 HP sizes are also offered tank mounted as the KRSDT. Start-up by a factory-trained technician is included.
