Kaeser Doubles Flow Range with New HBS Screw Blowers

Kaeser Compressors has expanded its screw blower product line to include new HBS packages. This series delivers 1,412 to 5,650 cfm at pressures up to 15 psig. With this expansion, Kaeser offers an innovative screw blower technology to an even wider range of applications with up to 35% more efficiency than conventional packages. Kaeser screw blowers are designed for wastewater aeration and other low-pressure applications where energy efficiency is critical. 

Kaeser HBS Blower

Kaeser expands its screw blower line with the HBS packages.

HBS series blowers feature the Sigma Profile airend, zero-loss direct drive technology and Sigma Frequency Control for superior energy efficiency across a wider range of flows than comparable screw and turbo blowers.

Consistent with Kaeser's other screw blowers, the blowers arrive on site completely assembled with inlet filters, silencers, and full sound-proofing enclosure. This completely integrated design approach has time and again helped contractors and operators reduce installation time and errors that come with onsite integration.

HBS blowers feature Kaeser's Sigma Control 2™ and a full complement of sensors to provide full visibility into its operational status, protect the machine, provide maintenance indicators and increase long-term reliability. Sigma Control 2 features broad communication capabilities including remote monitoring and e-mail notifications for service and alarms. HBS units can be seamlessly integrated into plants that are implementing IoT, Industry 4.0 or Water 4.0 strategies.
