*
Values within brackets [ ] are for H specification models (discharge pressure 0.83 MPa)
*
Discharge air volumes have been converted to compressor intake conditions.
*
Please be sure to use "KOBELCO" genuine oil" or the lubricating oil recommended by KOBELCO.
*
Noise values are measured at a height of 1.0 m and at a distance of 1.5 m in all directions from the compressor package in anechoic chamber and under full-loading operation.
Values within brackets [ ] are measured at a distance of 1.5 m from the front of the machine of and at a height of 1.0 m of it under full-loading operation.
*
Air produced by these compressors should not be used in respiratory equipment furnishing air for direct inhalation.
*
Since compressors depend on ambient air for cooling, the installation location must be properly ventilated to prevent ambient temperatures from rising above 40ºC.
*
Specifications and descriptions are subject to change without notice.
*
For other voltage specifications, please consult with nearest dealers.
*
Service factor(SF) of Main Motor is 1.1.
*
Be aware that a difference in water head level at cooling water inlet and outlet of 15 m or more may cause cooling water to flow too rapidly and cause the tube nest of the heat exchanger to erode. When the difference in water head level excceds 15 m, adjust the water feed valve to reduce the difference to 15 m or less(10 m or less for AG610W-5/6[H]).
