We accomplished the best-in-class specific power consumption and the highest level of durability by creating cutting-edge air-ends and optimised package design. This marks the beginning of a new standard for oil-free compressors.
Motor Output : 132 – 400kWDischarge Air Flow : 19.2 – 66.8 m3/min
Class-leading specific power consumption
The performance of the new ALE is evaluated based on specific power consumption, as per JIS B 8341: 2008 (equivalent to ISO1217 Edition 3). Because electricity consumption for customers is not shaft power and rated motor power but the compressor’s total input power, KOBELCO emphasizes the importance of both shaft power and the compressor’s total input power, which includes energy loss in the compressor.
Distinctive Design for Guaranteed Oil-Free Performance
KOBELCO’s dependable dual vent holes design ensures oil-free compressor chambers during the unload cycle.
Class 0 certified
KOBELCO’s Emeraude ALE series has received Class 0 certification (ISO8573-1 [-:-:0]) from the international test institute TÜV, signifying the highest purity level for compressed air quality classifications.
Long life cycle
Long Overhaul cycle has been achieved thanks to long life cycle bearings.
Remarkable Noise Reduction for Quiet Operation
Various noise control techniques have resulted in a substantial reduction in sound levels, creating a more comfortable working environment.

* Please refer to standard specification manual for water quality.
* Suction conditions Absolute suction pressure: 0.10MPa, Suction temperature: 20℃, Humidity: 0%RH.
* Discharge air volumes is converted to suction conditions.
* Discharge pressure are measured after gas coolers.
* Air produced by compressors should not be used in respiratory equipment furnishing air for direct inhalation.
* Nominal working pressure of 0.75MPa & 0.86MPa model is 0.70MPa.
* Nominal working pressure of 1.04MPa is 0.90MPa.
* Since the cooling for the compressed air & 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℃. ( For air-cooled 1.04MPa model, the surrounding air temperature should not exceed 40℃ )
* Please be sure to use the lubricating oil recommended by KOBELCO.
