Kaeser's 30 hp rotary screw compressors require three-phase electrical service. Three-phase motors draw significantly less amperage per horsepower than single-phase alternatives, run cooler, and operate more efficiently under continuous industrial loads. Before installation, confirm your facility's available voltage (typically 208V, 230V, or 460V three-phase), available amperage at the panel, and conductor sizing with a licensed electrician. Kaeser's technical team can provide electrical specifications for each model to assist with your installation planning.
