Precision machining
Highly accurate CNC machines grind the rotor profiles and gears to a tolerance of 1/1000 mm. The minimal gaps between the rotor tips and casing gaurantee the highest volumetric efficiencies and reduced slip. Every blower undergoes a strict dimensional check.

seals Piston-ring sealing
The heat-treated metal piston-ring air and oil labyrinth type seals provide long life, reliability and excellent sealing.
bearing Heavy-duty bearings
Cylindrical roller bearings are able to take up 100% of the widely varying radial forces occurring during operation.
precise synchronisation Precision gears
Spur-type, case-hardened, precision ground timing gears minimize vibration and mechanical noise, and allow accurate rotor to rotor timing for improved efficiency.
lobes Sealing strips
Specially designed rotor sealing strips reduce sensitivity to contamination and intermittent thermal overloading.
Solid block casing
The ribbed design of the single-piece cast casing body ensures optimal heat dissipation and torsional rigidity.
lubrication Reliable splash lubrication
Oil slingers mounted on both the drive-end and gear-end ensure reliable splash oil lburication to bearings and gears.
