Features
Features
Inverter Wide-Range Control
Allows lower pressure settings, delivering high energy savings and increased air capacity.
Low-Pressure Operation
Easily switch to low-pressure operation with a single touch on the monitor for more efficient energy use.
Operation up to 45°C Ambient Temperature
Stable operation even in high-temperature environments up to 45°C.
Dryer Pre-Operation
Standard dryer pre-operation prevents moisture from reaching the production line.
Drain Removal Operation
Maintains optimal discharge air temperature to ensure precise drain removal.
Dryer Drain Discharge Control
Optimizes drain discharge timing to minimize unnecessary air loss.
Stepwise Discharge Air Temperature Control
Automatically controls operating pressure when discharge air temperature exceeds the alarm level, reducing temperature rise.

** With suction throttling: 0.9 MPa (G)
*Suction conditions: Atmospheric pressure, temperature 2–40°C
*Discharge conditions:
Discharge air temperature:
Without dryer: 50°C(Air-cooled, ambient temperature 30°C condition)
*The stated air delivery is the actual air volume discharged from the compressor outlet, converted to suction conditions (downstream of the suction filter).
*Air delivery decreases by approximately 3% during condensate discharge.
*The discharge pressure sensing point is located downstream of the aftercooler
(for models 11 kW and below, downstream of the pressure holding check valve).
*Noise levels are measured at 1.5 m from the front of the unit and 1.0 m above the floor under full-load operation, converted to anechoic room conditions.
Values may vary depending on installation environment and capacity control operation.
In locations affected by surrounding reflected sound, the actual noise level may exceed the indicated values.
*Compressed air must not be used for respiratory purposes by direct inhalation
*The unit is cooled using the ambient air at the installation site.
Please ensure adequate ventilation so that the ambient temperature does not exceed 45°C.
Appearance and specifications are subject to change without prior notice.
*Weight values are based on the 200V class.
*Lubricating oil quantity indicates the amount required for periodic oil replacement.
*Compressors are shipped with “Initial Filling Lubricating Oil EX.”
For oil filling or replacement, please use genuine KOBELCO SCREW Oil “KOBELCO EXTRA-OIL.”
*For 60 Hz models, the thermal relay settings at shipment are configured for power supply voltages of 220V / 440V.
When operating at 200V / 400V, please adjust the thermal relay settings by turning the dial.
Refer to the operation manual for details.
