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.

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
