Rotary Screw Air Compressors

Compact and robust next gen HGS - HSC compressors ensure optimum solutions for small and medium-sized businesses and workshops.

 Advantages 

• One of the products in its class that takes up the least footprint.

• Blind cover allows you to place it up against the wall. Convenient placement makes for easy servicing, maintenance, and access. (22 kW and below)

• Optimized intake chamber and insulated cold air intake increase energy efficiency. (30 kW and above)

• Compact design has the compressed air widget and compressor in a single place meets your expectations and demands at the optimal level.

• Efficient motor keeps energy use and costs down.

• High-quality components for a long service life and low maintenance costs.


 General Features 

• Next gen screw block and motor

• Electronic control

• Designed for continuous operation

• Dryer & tank mounted option (2,2-22 kW)

 Screw Block 

• Durable screw block provides high-capacity air and is specially selected for each model’s capacity requirement

• Operated in high ambient temperatures and offers superior reliability

• Air production with less loss thanks to new rotor profiles

• Next gen bearing design which increased load-bearing capacity

• Low maintenance and replacement costs


 Main Motor and Drive System 

• IE3 efficiency-class electric motor

• Star/delta motor starter

• Belt-pulley drive system

• Easy-to-use belt tensioner

• Pulley bushing for easy servicing

 Intake System

• Optimized air intake chamber to separate cool air intake and hot air discharge

• Insulated cold air intake for energy efficiency (30 kW and above)

• Optimized noise levels


 Air Filter

• Two-stage filtration (initial filtration/precision filtration) (18 kW and above)

• 99.9% efficiency in particle separation down to 3 microns

• Low pressure loss

• Easy maintenance

• Long service life

 Cooling System

• High efficiency thanks to optimized cooling performance

• Temperature-controlled additional axial fan (30-75 kW)

• Minimum footprint with quiet and effective axial fan coupled directly to the main motor (2,2-22 kW)

 Oil Separator

• Longer lasting separators keep maintenance costs down

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

Controller

• Without the need for an external main controller, ability to co-aged work synchronized with Master/Slave for up to two compressors

• Internal ModBus communication

• User-friendly on-screen interface

• Alarm log records last 20 alarms

• Maintenance warnings and log records

• Weekly scheduler for starting/stopping the machine at 3 different time intervals can be individually set for each day of the week (45 kW and above)
