Kaeser rotary screw compressor families and model guides, with buying advice and help for existing owners.
Kaeser’s US rotary screw lineup runs from compact SX, SM and SK machines through larger AS, ASD, BSD, CSD, DSD, ESD, FSD and HSD compressors. SFC identifies variable-speed machines. Model numbers are not a universal horsepower scale: compare the specifications for the actual model.
Package names also appear in quotations. A T suffix identifies an integrated dryer on the listed models, while AIRCENTER packages combine the compressor with air treatment and a receiver. Check the complete package before comparing price, footprint or electrical requirements.
For troubleshooting, record the model, serial number and controller message. Kaeser has reused familiar family names over time, so an older machine can need different procedures and parts from a current model with a similar name.
