HBC Series

Compact footprint

The Com-paK blower package’s unique component layout 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 blower packages to be installed side-by-side without the need for additional access clearance.

Omega Tri-lobe Blower Profile

Kaeser’s Omega blower profile is our proprietary design and 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.

Quiet operation

Anti-vibration pads absorb vibrations before they reach the floor or sound enclosure.

Low pulsations and quiet operation

Com-paK units feature Kaeser’s Omega tri-lobe blowers with unique pressure equalization channels to substantially reduce pulsations. Lower pulsations mean less stress to sensitive process equipment and significantly reduced noise levels. Plus, the Com-paK enclosures are built for exceptional noise attenuation and use heat-resistant Trevira® polyester wool.

Low operating costs

Over the lifetime of any blower system, energy costs far excced the initial capital cost. Every Kaeser blower package is equipped with high efficiency Omega Profile rotors and conservatively-sized EPAct compliant TEFC/IP-55 motors to ensure maximum energy savings and outstanding system performance.

Simple maintenance

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

Automatic belt tensioning

The automatic V-belt tensioning device with visual indicator minimizes transmision 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.

Effective cooling

The combination of air ducts in the sound enclosure and powerful fans create a highly efficient cooling system that ensures effective cooling even for frequency-controlled units.

Outdoor installation

Installing Kaeser blower packages outdoors is easy and inexpensive. Units can be equipped with specially designed rainproof air inlets and bird protection screens, enabling normal outdoor operation.
