Features
Highly efficient Two-stage compression
Emeraude FE's Two-stage compression is 8 to 28% more efficient than typical single stage oil-free screw type.
Also, it can decrease discharge temperature which leads to reliability.
Why Energy saving?
- Less power is required because discharge air from 1st stage is cooled by inter cooler and air volume for 2nd stage can be decreased accordingly.
- Less air leakage in each compression chamber with less compression rate for each stage.
User friendly LCD controller (Common to FE)
This monitor can be used not only to keep track of the operating conditions but also to set the discharging pressure, etc. The operating records, graphic displays, weekly timers, daily reports and weekly report management, can be conducted.
- Operation data can be output through "Modbus" (optional).
- The front control panel of the controller is complete with a waterproof specification equivalent to IP65.
Proven reliability
- KOBELCO's unique dual vent holes design prevents oil entry in compressor chamber and ensure "Oil-free".
- State-of-the-art "Gamma Profile" Rotor and Casing with advanced FEM analysis enhances reliability of heart of compressor.
- MoS2 coated Air-ends and 2nd stage's stainless steel improve anti-corrosion.
- Designed for continuous operation under 40°C ambient condition with +5°C allowance.

*Nominal working pressure is 0.88MPa.
* 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 40℃.
* Please be sure to use the lubricating oil recommended by KOBELCO.
* Specifications and appearances are subject to change without notice
Contact us if guaranteed values of performance is needed. Starting system of fixed speed model is Star-Delta.
〈 〉for built-in dryer type.
* Discharge air volumes is converted to suction conditions (30℃).
* Discharge pressure are measured after gas coolers.
* Noise values is measured at 1.5m away from the machine front and 1m from the floor in the anechoic room, with the machine being operated at its full load.
* Air produced by compressors should not be used in respiratory equipment furnishing air for direct inhalation.
