SM SFC to HSD SFC series compressors from Kaeser are exceptionally efficient variable-speed rotary screw compressors. SM, SK and ASK SFC models use Kaeser’s minimal maintenance V-belt drive system, which features automatic belt tensioning to ensure optimum power transmission. Larger models from the ASD SFC upwards are equipped with the speed-controlled 1:1 direct drive.
The large, slow-speed KAESER airends with energy-saving SIGMA PROFILE rotors provide outstanding performance across the entire control range.
Every Kaeser SFC compressor model is capable of 100 percent duty cycles without any increase in maintenance requirement.
If installed, it is the frequency-controlled compressor that runs for longer than any other unit within the compressed air station. KAESER SFC models are therefore designed with maximum efficiency and low-speed operation in mind. This saves energy, extends service life and enhances reliability.
The soft rise in motor starting current from zero to full load without current spikes leads to an almost unlimited motor starting frequency (the number of possible motor starts within a given time period without overheating occurring). The continuously variable acceleration and deceleration significantly reduces component stress. (SX series models feature an external separator cartridge)
