      Kaeser Industrial Rotary Lobe Bare Blowers

      Advanced Industrial Blower Design

      All Omega industrial blowers share a durable design that includes rigid casings, cast bearing supports, and one-piece rotors. The substantial casing construction and proprietary port design ensure smooth, quiet operation at all speeds. The precision-machined, case-hardened, spur-type timing gears and oversized cylindrical roller bearings provide years of reliable service. Piston-ring seals ensure optimum sealing and oil-free air. Heavy-duty construction provides longer service life and quiet operation.

      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.

      Piston-ring sealing

      The heat-treated metal piston-ring air and oil labyrinth type seals provide long life, reliability and excellent sealing.


      Heavy-duty bearings

      Cylindrical roller bearings are able to take up 100% of the widely varying radial forces occurring during operation.


      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.


      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.


      Reliable splash lubrication

      Oil slingers mounted on both the drive-end and gear-end ensure reliable splash oil lburication to bearings and gears.

      Special application blowers

      Gas Tight Blowers (N Series) - Flows to 5650 CFM, Pressure to 15 PSIG

      For nitrogen and other gas conveying applications, Kaeser's Omega N Series blower is available up to 5650 CFM. The single envelope design can be configured into special packages with an input shaft sliding-ring seal.

      Steam Blowers (B Series) - Flows to 2900 lbs/hr

      Kaeser's Omega B Series blowers are specifically designed for compression of water vapor with vacuum operation in combination with water injection cooling. They feature Ni-Resist 3 casings, G-X8 CrNi stainless steel rotors, and Teflon shaft seals with stainless steel sleeves. 


      Vacuum Boosters (VWC Series)

      Used in combination with a primary stage pump, the Omega WVC significantly increases pump suction capacity and vacuum performance. Optional frequency converters enable simultaneous activation of rotary vacuum and backing pump at atmospheric pressure to significantly reduce pumping time and increase efficiency.


      Vacuum Blowers (PV Series) - Flows to 4200 CFM @ 23.5" Hg

      For use in vacuum ranges up to 27" Hg vacuum. Kaeser's PV blowers have a unique design with pre-inlet injection cooling that is resistant to contamination in the air stream.
