11-37 kW   16-20 bar  0,16-3,9 m³/min


Oil Injected, Direct Coupled, Variable Speed

High Pressure Rotary Screw Air Compressors

 Advantages

• It saves up to 55% energy.*

• It operates at constant output pressure value.

• It provides effective and energy efficient compressed air production even in case of highly variable compressed air requirements.

• Long component life cycle thanks to soft start.

• It has the feature of protecting against the adverse effects of peak currents.

* When compared with compressors without an inverter for applications with variable requirements


 General Features

• IE5 high efficiency-class IPM electric motor

• Operating with low noise level

• Soft start with variable speed power transmission 


 Electric Motor

• IE5 Ultra Premium energy efficient Internal Permanent Magnet (IPM) electric motor

• Compact design

• Low noise level

• F-class insulation

• Optimum oil cooling at all speeds for high efficiency

• Grease-free lubricated motor bearings

 Air & Oil Separator

• Effective separator elements keep the amount of oil in the outlet air low (1-3 mg/m³) for highquality compressed air

• Easy-to-detach spin-on type separator 


 Intake System

• Air circulation inside the cabin with negative pressurized cabin andsealed cover structure.

• Fresh air intake thanks to hot air evacuated at a point away from the suction.

• Low noise level thanks to intake blinds.


 Cooling System 

• Temperature controlled axial fan (15 kW and below)

• Optimum working temperature thanks to inverter controlled fans, provides additional energy efficiency (18 kW and above)

• High-pressure-resistant cooler


 Water Separator

• Separation performance is >%99 even in very hot and humid conditions

• Compact, integrated and unique design 

(18 kW and above)

• High energy efficiency with minimal pressure loss 

(18 kW and above)


 Controller

• User-friendly display interface with 7” LED display

• Group operation of up to 4 compressors

• Possibility to choose Master/Slave compressor

• Ability to connect to customer DCS system via ModbusTCP

• Compact construction with integrated driver and controller

• Weekly scheduler for starting/stopping the machine at 2 different time intervals can be individually set for each day of the week

• Dual PID feature can run simultaneous PID for temperature and pressure

• Pressure PID ensures energy-efficient operation by maintaining the pressure at the desired level

• Temperature PID controls the fan speed to maintain the screw block’s most efficient operating temperature 

• All inverter and compressor control data are managed from a single point

• Ability to determine co-aging times of the system with selectable parameters

• Built-in phase sensor
