Two-stage compressor is equiped for energy saving, reducing life-cycle cost and improving eliability.
It can achieve 9～34% higher efficiency compared with single-stage oil-free screw compressor.
Inverter Cooling Fan （FE200～790）
In the Emeraude-FE series, the cooling fan is also controlled by the inverter to further save energy.

Low noise
In the Emeraude-FE series, the cooling fan is also controlled by the inverter to further save energy.
Improvement on durability for ambient
Reviewing the total cooling system including design of coolers and cooling fan with safety margin, the compressor can operate even under ambient temperature of 45oC.
