Features
Features
Best in Class discharge air flow
New KOBELION SG achieves best-in-class discharge air flow, and max 13% increase from existing model, thanks to New Generation Air-end.
Direct Gear Drive
Designed to achieve best efficiency in rated load. Precise machined helical gears are directly mounted on motor shaft and eliminate coupling or v-belt. Single piece drive train minimize vibration of rotating part and mechanical losses. Also adjusting and replacing of v-belt is no longer necessary. All the model is with IE3 premium efficiency motor*.
* Except for 200V/60Hz, 400V/60Hz
Energy saving logic
KOBELCO’s "Energy saving logic" can reduce pressure band of load/un-load control to eliminate excess pressure hike.

Main Motor: 2-pole, TEFC induction motor, Class F, Star-delta drive
Electrical spec: Three-phases, 200/200・220V (380・400・415/400・440V)
[ ] for initial charge
* Suction conditions: Atmospheric pressure/2 to 45℃
* Discharge condition: below 45℃ (ambient temperature: 30℃)
* Discharge air volume is converted to suction conditions.
* Discharge pressure are measured after coolers.
* Air produced by compressors should not be used in respiratory equipment furnishing air for direct inhalation.
* Nominal working pressure is as per below;
0.75MPa variant: 0.7MPa
0.85MPa variant: 0.8MPa
1.05MPa variant: 1.0MPa
* Noise values are based on the height of 1.0m and at the distance of 1.5m in front from the compressor package in anechoic chamber and under full-load operation.
* Since the cooling for the compressor air, lubricant, and the inside of the compressor unit depends on the surrounding air condition,
the surrounding air must be properly ventilated to prevent the ambient temperature from rising above 45℃.
* Specifications and descriptions are subject to change without notice.
* Weight values are based on 220/220V model for air cooled type, 380/415V model for water cooled type.
* For water cooled model: If the head of water supply and drain exceeds 10m, erosion may happen inside a heat exchanger. In that case, please adjust a hydraulic pressure with a water supply valve.
