Standard equipment includes a new generation air-end, direct gear drive, and IE3 premium efficiency motor. Innovative technology is incorporated as an industrial compressor for the greatest level of reliability and straightforward controllability. Motor output: 15 – 90kW Discharge air flow: 2.18 – 17.8m3/min
Outstanding Discharge Air Flow
Thanks to the New Generation Air-end, the New KOBELION SG achieves best-in-class discharge airflow and a maximum 17% increase over the previous model.
Direct Gear Drive (AG/SG)
Designed to maximise efficiency at rated load. In order to avoid coupling or a v-belt, precisely machined helical gears are directly placed on the motor shaft.
Single-piece drive trains reduce mechanical losses and rotating-part vibration. V-belt replacement and adjustment are also no longer required. Every model has a motor with IE3 Premium efficiency.
Energy saving logic
The “Energy Saving Logic” of KOBELCO can narrow the load/unload control pressure band and prevent excessive pressure increases.
Up to 50°C ambience
A sufficient temperature buffer was built into the design, allowing for continuous operation up to 45°C and operating up to 50°C.
