Every KAESER rotary screw vacuum 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. Single-stage vacuum generation with liquid injection provides optimum cooling, lubrication and sealing of the rotors.
As the most efficient way to achieve a given drive power, KAESER uses large, low-speed rotary screw vacuum airends. This ensures that the specific power is always within the optimal range. Using a flexible V-belt drive with automatic belt-tensioning, airend speed is precisely matched to suit the specific airend installed in the pump package.
