An inverter or frequency-controlled compressor (variable speed) delivers compressed air at a preset final pressure. If the compressed air demand varies, the compressor’s speed adjusts accordingly. This intelligent control allows for energy savings of up to 35%. The frequency-controlled compressor is particularly recommended for frequently fluctuating compressed air consumption and an operation of more than 2,500 running hours per year.

Model Flexi screw compressors are equipped with frequency control.
