37-90 kW   7-8,5-10 bar  3,8-15,5 m³/min


Oil-Free, Two-Stage, Direct Coupled, Fixed/Variable Speed

Rotary Screw Air Compressors

We offer more sustainable, Class 0-certified , fully oil-free air solutions for the food, beverage, chemical and electronics industries.

 Advantages 

• Produces less filter waste than oil-injected compressors, which reduces your maintenance costs down.

• It can be used safely in sensitive industries such as food and pharmaceutical for the highest hygiene.

• Highly durable performance suitable for working in the harshest operational conditions.

• Models with VSD technology save up to 35% energy and reduce your energy costs.

• Special venturi design prevents rapid pressure fluctuations and high-frequency vibrations.



 General Features 

• IE4 efficiency-class electric motors

• Soundproofed canopy

• Electrostatic coated canopy components for high corrosion resistance

• Electric motor protection to prevent overload

• Air-cooled and water-cooled options available

• Fixed and variable speed drive options

• Soft starter at fixed speed models

• Direct coupled drive system

 Screw Block

• Two-stage screw block

• Bearing system developed with the latest technology ensures long life and vibration-free operation

• High level sealing system ensures high performance even during long operation periods

• Synchronizing gears for contact-free power transmission between the rotors

• Specially coated rotors and rotor housing internal parts for minimum gap tolerance and high efficiency

• Stainless steel rotors to eliminate the risk of corrosion and locking, for a long service life

• Ultracoat coating for high temperature resistance

  Cooling System

• Two-stage cooling with pre-cooler system made of stainless steel pipes and fins

• After-cooler with aluminium bar and plate system

• Easy to maintain and clean

• Washable panel filter

• Optimum in-cabinet air circulation to keep the motor and screw block cool


 Intake Regulator

• Easy-to-maintain and reliable valves not affected by pollution and condensation

• Hydraulic intake regulators are more reliable and easier to maintain than pneumatic intake regulators


 100% Oil-Free Compressed Air

• It is designed in accordance with sensitive and accurate production conditions.

• It protects the environment and saves energy.

• It is produced in accordance with all global standards and regulations.

• It prevents damage to your products and the contamination of your production lines. 

• Therefore, it eliminates unnecessary machine downtime. 

• It guarantees the high quality compressed air you need.  

 Controller

• Without the need for an external main controller, ability to work synchronized for up to 5 compressors

• Weekly scheduler for starting / stopping the machine at 3 different time intervals can be individually set for each day of the week

• Dual PID feature on inverter-equipped models can run simultaneous PID for temperature and pressure

• Pressure PID on inverter-equipped models ensures energy-efficient operation by maintaining the pressure at the required level

• Temperature PID on inverter-equipped models controls the fan speed to maintain the screw block’s most efficient operating temperature

• On inverter-equipped models, all inverter and compressor control data are managed from a single point

• Internal ModBus communication

• User-friendly on-screen interface

• Alarm log records the last 20 alarms

• Periodic maintenance warnings and log records
