Three Lobe Blower

Challenge: How to get the fine tolerances and quality build characteristics of a top quality machine from a "compact" design.

Myth: Compact designs do not allow for precision machining and optimal clearances.

Learn from us: Kaeser Compressors provides an unmatched level of quality and precision to the design of its Com-paK Plus tri-lobe blower package. These complete, ready to install packages include the famous Kaeser Omega Plus tri-lobe blower. This assures you of quality design and reliable operation. These units are packed with innovative features including:

  • wideband inlet
  • discharge absorption silencers
  • integrated inlet filter
  • belt guard
  • pressure relief valve

The Hope Group responds: At The Hope Group we recommend
Kaeser blowers for a variety of applications:

  • waste water treatment
  • printing works
  • flash evaporators
  • bulk conveying

Com-paK Plus

The Kaeser Com-paK Plus blower package provides many design and operating efficiencies that you will come to appreciate over its many years of trouble-free use. All routine maintenance points are located on the front of the unit. There are wide, easy opening doors for access and gas springs safely support the sound enclosure's hinged lid. You can read about a recent installation of Kaeser blowers at NH Gas in Keene, NH.

The compact unit has a unique component layout that minimizes space requirements. All maintenance and access points are located on the front while all process and utility connections are located on the back. This enables multiple packages to be installed side-by-side without the need for additional access clearance.

Omega Plus Tri-lobe Profile

Kaeser's Omega Plus profile is a proprietary design and is machined to the finest tolerances for optimum internal clearances. The enhanced tri-lobe design provides significantly reduced pressure pulsations and lower noise levels. Precision machined, case-hardened, spur-type timing gears in conjunction with oversized cylindrical roller bearings provide years of reliable service.

Automatic belt tensioning

The automatic V-Belt tensioning device with visual indicator minimizes transmission losses and extends belt life for increased reliability and reduced maintenance.

Easy fluid checks

High visibility oil sight glasses allow the fluid level to be easily checked from the front of the unit.

Simple maintenance

Drain valves with gasketed caps mounted in front, just inside the access door simplify oil changes.

Effective cooling

Ventilating ducts strategically located in the sound enclosure and an independently-driven radial-fan, ensure sufficient cooling to the blower and motor.



Three-Lobe Blower
The Kaeser Three-Lobe Blower is a compact unit with a unique component layout that minimizes space requirements, places all maintenance and access points at the front, and all utility connections at the back to enable multiple packages to be installed side-by-side.
