Efficient KAESER V-belt drive

KAESER screw compressors with V-belt drive provide outstanding efficiency and reliability. KAESER was one of the first compressor manufacturers to introduce the V-belt drive system. The KAESER drive is characterised by an automatic tensioning device that ensures constant transmission efficiency and reduced maintenance costs. SX series models are equipped with a flat drive belt that does not require additional tensioning.

Sigma profil   Save energy with the KAESER SIGMA PROFILE
Every KAESER rotary screw airend is equipped with energy-saving SIGMA PROFILE rotors. Components manufactured to the highest standards and precision aligned roller-bearings ensure long service life with maximum reliability.

Sigma control   SIGMA CONTROL 2
The control unit features an easy to read display and durable input keys. All relevant information can be viewed at a glance and user-friendliness is further enhanced by the logical menu structure coupled with the ability to display data in any one of 30 selectable languages.
belt tensioning   Automatic belt tensioning
The automatic belt tensioning device ensures consistent transmission efficiency and excellent drive-system reliability.
(Not required for SX series)
filter   Cooling air filter mats
Ambient air used for cooling is contaminated to some degree, but the filter mats through which the air is drawn into the cabinet prevent the cooler from clogging.
seperation system   Optimised separation system
The combination of optimum flow separation and the special separator cartridge results in a minimal fluid content of less than 2 mg/m³ in the discharged compressed air. The separator system also requires very little maintenance.
(SX series models feature an external separator cartridge)
