The Kaeser SK Series provides continuous-duty compressed air for facilities requiring 38 to 97 cfm at working pressures up to 217 psig. Engineered around Kaeser's energy-saving SIGMA PROFILE® airend and built with low-maintenance drive components, the SK Series combines high output with minimal power consumption to lower your facility's total cost of ownership.

• SIGMA CONTROL Automation: The SIGMA CONTROL continuously tracks operating metrics, predicts maintenance needs, and integrates with factory management systems or the SIGMA AIR MANAGER 4.0 master controller.
  Standard Anybus Interface: It connects to your PLC or SCADA network via interchangeable communication modules.
  Supported Protocols: Modbus TCP, PROFIBUS DP, PROFINET IO, EtherNet/IP, BACnet/IP, and OPC UA.
• Power-Saving SIGMA PROFILE® Airend: Precision-machined rotors deliver up to 30% energy savings compared to conventional rotary screw designs.
• TEFC Motor & Reduced Voltage Starter: Premium-efficiency totally enclosed fan-cooled motors come standard with wye-delta starters to eliminate high electrical current surges on startup.

• Automatic Belt Tensioning System: Maintains correct drive belt alignment and tension automatically. This eliminates power loss from slippage, prolongs drive component life, and lets maintenance staff inspect belt condition through a side cabinet window.
• 3-Stage Fluid Separation: Centrifugal separation combined with dual coalescing filters reduces oil carryover to under 2 ppm, keeping downstream air distribution clean and protecting filtration equipment.

• Heavy-Duty Acoustic Cabinet: Sound-dampening insulation keeps operating noise between 66 dB(A) and 68 dB(A), enabling placement near production lines without excessive workplace noise.
• Dual-Zone Cooling System: A separate air intake path cools the motor and heat exchangers independently, preventing internal heat buildup and extending fluid service life.
• Streamlined Maintenance Access: Fast-opening enclosure panels allow easy access to all service points, including spin-on fluid filters and air intake cartridges.

Select the package structure that fits your plant space and air treatment requirements::

• Standard SK Models (SK 12, SK 15, SK 20): Standalone rotary screw compressors engineered for connection to facility air lines and receiver tanks.
• Integrated Dryer "T" Models (SK 12T, SK 15T, SK 20T): Housed in a thermally isolated cabinet, the built-in refrigerated air dryer includes energy-saving cycling controls, a zero-loss ECO-DRAIN, and environmentally responsible R-513A refrigerant
• Complete AIRCENTER Systems: An all-in-one package that integrates the SK compressor, refrigerated dryer, and receiver tank into a single space-saving unit.
• Variable Speed (SFC) Drive Option: Available as an SFC configuration to match fluctuating plant air demand. Learn more on our Variable Speed Drive (SFC) Page.

• Precision Sheet Metal & Fabrication Shops: Provides continuous, high-volume airflow for smaller plasma cutters, press brakes, deburring stations, and multiple handheld grinders running at the same time. 
• Plastics Fabrication & Thermoforming: Powers pneumatic mold clamps, vacuum generators, and material conveyors that demand stable line pressure during continuous multi-hour runs. 
• Commercial Laundry & Dry Cleaning: Delivers steady, dry air to garment presses, automated folding machinery, and sorting systems while maintaining low utility power draw.
