125-430 HP   100-125-150-175 psi  171-2.242 cfm


Oil Injected, Two-Stage, Direct Coupled, Variable Speed

Rotary Screw Air Compressors

Next gen compact compressors maximize your energy saving, minimize your total cost of own.

  General Features 

 IE4 efficiency-class electric motors

 Two-stage screw block

 Variable and fixed speed motor power options

 Water cooling and heat recovery (optional)

Operating with low noise level

 Screw Block

Two-stage screw produces energy efficiency by up to 10%

Higher flow rate by up to 10% comparing to single stage

Direct coupled

Reduced internal losses

Thanks to low compression rate, low axial and compression forces

Thanks to low rotor speeds, a long service life

With two-stage compression near isothermal compression

Reduced axial and compression forces resulting in longer screw and bearing service life


 Electric Motor

IE4 efficiency-class electric motors

Motors have B-class temperature increase

Continuous operating feature

  Oil Filter

Eco-friendly and recyclable oil filter

Oil filter contains no metal alloys

Aluminium housing

Easy maintenance


 Water Separator

Compact, integrated, and unique design

Reliable initial separation (>% 99)

High separation efficiency at high humidity and temperature

• Zero loss drain

High energy efficiency with minimal pressure loss

 Air Filter

Protects the screw block by separating particles down to 3 microns

Intake pressure loss: <2 mbar results in high efficiency throughout the maintenance period

Easy maintenance

Long service life

  Cooling System

 High cooling efficiency in compact air and oil heat exchangers

Suitable design for operating up to 45°C

Low noise level with low speed radial fans

Energy efficiency with optimum oil temperature thanks to VSD-controlled radial

 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
