Kaeser CSG.1 rotary screw compressors

Food and beverage applications have especially high demands when it comes to compressed air quality. For these sensitive processes, Kaeser Australia has released the latest class 0 oil-free compressor, certified by the TÜV in accordance with ISO 8573-1.

The CSG.1 rotary screw compressors have air flow rates ranging from 4 to 15 m³/min and pressures up to 11 bar.

The CSG.1 can be specified as a fixed speed, fixed flow rated machine or, for applications with fluctuating compressed air demand, variable speed controlled SFC versions are available. The updated series delivers 16% higher flow rates from the same power-rated motor as previous.

Kaeser’s patented, energy-efficient Sigma Profile rotors now feature a wear-resistant PEEK coating, which is designed to result in an airend that will exhibit no air flow loss during its lifetime.

Developed in-house, the special coating has three layers: nanoceramic, PEEK basecoat and topcoat. This coating is biocompatible, FDA-certified and compliant with European requirement VO 1935 for food contact materials, making it suitable for use in the food and beverage industries.

The CSG.1 will be on display at APPEX stand B145.
