Precision machining
Advanced CNC-controlled machining centres enable rotor profiles and gears to be precision machined within a tolerance of a thousandth of a millimetre. Minimal clearance between the ends of the rotors and the block casing ensures outstanding efficiency due to exceptionally low air reflow – this also allows low speed blower operation. Discharge air temperatures of up to 160 °C are possible, as the blower block is heated very little during operation. All block casings and rotors are manufactured within exact tolerances to guarantee consistently high product quality.

 | Non-wearing seal
Well-proven piston ring labyrinth seals with pressure relief channels between the flow- and oil-chambers are fitted as standard.
|
 | Generously sized bearings
Heavy-duty cylinder roller bearings completely absorb the continuously changing radial gas-forces that are exerted on the rotors. As a result, they avoid the springing effect of self-aligning bearings and last up to ten times longer with the same loading.
|
 | Precision synchronisation
High precision 5f 21-rated spur-ground timing gears have minimal flank clearance and a play major role in contributing to the block’s outstanding volumetric efficiency.
|
 | Stable rotors
Kaeser OMEGA PROFILE rotors are manufactured from single work pieces to ensure stable, vibration-free performance with minimal sound levels. The rotor lobes are equipped with integrated sealing strips that reduce sensitivity to contaminated intake air and thermal overloading.
|
 | Solid block casing
The ribbed design of the single-piece cast casing body ensures optimal heat dissipation and torsional rigidity.
|
 | Optimised lubrication
Oil slinger-discs at each shaft end ensure that all relevant bearings and gears are evenly lubricated.
