Class-leading specific power consumption

New ALE's performance is evaluated by specific power consumption as per JIS B 8341: 2008 (ISO1217 Edition3 equivalent).KOBELCO places an importance on not only shaft power but also compressor's total input power including energy loss in the compressor because electricity consumption for customers is not shaft power and rated motor power but compressor's total input power.

Unique design to ensure "Oil-free"

KOBELCO's proven dual vent holes design prevents oil entry in compressor chambers during unload running.

Big touch color monitor

Class 0 certified

KOBELCO has received Class 0 certification (ISO8573-1 [-:-:0]) for〈Emeraude ALE〉series from international test institute called TÜV which certifies the highest level of purity for quality classifications of compressed air.

Class 0 certified

Long life cycle

Long Overhaul cycle has been achieved thanks to long life cycle bearings.

Long life cycle

Outstanding quietness

Various noise control techniques has drastically reduced sound level.Making the working environment more comfortable.

* Suction conditions Absolute suction pressure: 0.10MPa, Suction temperature: 30°C, Humidity: 75%RH
* Discharge air volumes is converted to suction conditions.
* Discharge pressures are measured after gas coolers.
* Air produced by compressors should not be used in respiratory equipment furnishing air for direct inhalation.
* Nominal working pressure![0.75MPa model: 0.70MPa, 0.86MPa model: 0.80MPa, 1.04MPa model: 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°C.(For air-cooled 1.04MPa model, the surrounding air temperature should not exceed 40°C)
* Please be sure to use the lubricating oil recommended by KOBELCO.
* Appearance and specifications are subject to change without notice.
* Consult us individually, regarding guaranteed performance values.
* For other voltage variants, please consult us.
