Industrial Blower Packages with Integrated Controls


Kaeser has been a leader in creating fully packaged blower systems that are reliable, durable, energy-efficient, and simple to maintain. Our line of Com-paK blower packages set the standard in the blower industry.

The Com-paK BB, CB, DB, EB, and FB packages include the Sigma Control 2™ with Omega Control software. In addition to monitoring all onboard sensors, the Sigma Control 2 features expanded communication features. The expansive communications capabilities of the Sigma Control 2, with an Ethernet port and built-in Web-server, enable remote access and seamless integration into plant control/monitoring systems such as Kaeser’s Sigma Air Manager (SAM). ModBus, Profibus, Profinet, and Devicenet industrial communication interfaces are available
