KAESER Aircenter SK (11–15 kW)
High-performance compressed air stations with refrigerated dryers and 350-liter tanks – 11 to 15 kW for production
The KAESER Aircenter SK Series offers ready-to-use compressed air stations with an integrated refrigeration dryer and a 350-liter tank for production. Models range from 11 to 15 kW, with operating pressures from a maximum of 8.5 to 15 bar, and feature the SIGMA CONTROL 3 M controller with an AnyBus interface for connection to higher-level control systems.
Which KAESER Aircenter SK Compressed Air Station for Your Production?
The KAESER Aircenter SK Series is the most powerful line of KAESER compressed air stations and combines a screw compressor, a refrigeration dryer, and a 350-liter compressed air receiver in a robust, all-in-one system for production. With drive power ranging from 11 to 15 kW, the Aircenter SK delivers air flow rates of up to 2.46 m³/min and, with operating pressures ranging from 8.5 to 15 bar, meets even the most demanding industrial requirements.
Overview of all Aircenter SK models
The sizes of the KAESER Aircenter SK Series at a glance:
| Model | Performance | Max. Overpressure | Volume flow | Sound Level | Variants |
|---|---|---|---|---|---|
| SK 23 | 11.0 kW (IE3) | 8.5 / 12 / 15 bar | 1.92 / 1.59 / 1.37 m³/min | 66 dB(A) | SK 23-8.5, SK 23-12, SK 23-15 |
| SK 26 | 15.0 kW (IE3) | 8.5 bar | 2.46 m³/min | 67 dB(A) | SK 26-8.5 |
SK 26
Power: 15.0 kW (IE3)
Max. Overpressure: 8.5 bar
Airflow: 2.46 m³/min
Sound Pressure Level: 67 dB(A)
Variants: SK 26-8.5
Which Aircenter SK model is best for which application?
The choice of the right model depends on the compressed air demand and the required operating pressure. The Aircenter SK 23 with 11.0 kW is the most versatile model in the series: With three pressure stages—max. 8.5, 12, and 15 bar—it is suitable for both standard production needs and high-pressure applications such as laser machines or pressure testing. At a maximum of 8.5 bar, it delivers 1.92 m³/min; at a maximum of 15 bar, it still delivers 1.37 m³/min. The Aircenter SK 26 with 15.0 kW is the top-of-the-line model and, with a flow rate of 2.46 m³/min at a maximum of 8.5 bar, reliably supplies even facilities with the highest compressed air demands.
Aircenter SK or SK Standard – with or without a refrigerated dryer?
KAESER offers the SK screw compressors in two versions: as the Aircenter SK with an integrated refrigeration dryer and a 350-liter compressed air receiver, or as the SK Standard or SK T without a tank. The Aircenter model is a ready-to-use, complete “plug & work” solution—ideal for businesses that need a compressed air station with integrated treatment that’s ready for immediate use. The standard SK or SK T models are suitable for businesses that already have a separate compressed air receiver and a central treatment system, or that wish to integrate the compressor into an existing compressed air system. On the respective product page, you’ll find the appropriate counterpart under “Alternative Products.”
Features and Technology of the Aircenter SK
Every KAESER Aircenter SK is delivered as a complete, ready-to-operate system. The oil-lubricated screw compressor block with a SIGMA PROFILE rotor pair is designed for operating pressures up to 15 bar and is driven by an IE3 motor. The 350-liter compressed air receiver and the integrated refrigeration dryer with the refrigerant R-513A (GWP 629, pressure dew point +3 °C) form a compact unit with a footprint of just 750 × 1345 mm. The SIGMA CONTROL 3 M with a 5-inch color touchscreen offers the broadest protocol support in the Aircenter family via the AnyBus platform: PROFIBUS DP, PROFINET IO, Modbus TCP, EtherNet/IP, BACnet/IP, and OPC UA are available as modules—allowing the Aircenter SK to be integrated into virtually any existing automation environment. The ECO-DRAIN condensate drain operates with electronic level control. All that is needed for commissioning is a power connection (400 V / 3-phase / 50 Hz) and a compressed air line (G 1).
Production quality from the KAESER plant
The Aircenter SK Series is manufactured at KAESER’s main plant in Coburg. The SIGMA PROFILE compressor block, designed for high-pressure applications up to 15 bar, undergoes particularly rigorous manufacturing inspections. Before shipment, each unit undergoes a comprehensive test run under real production conditions at full pressure load—ensuring maximum process reliability from the very first day of operation.
