Kaeser Compressors DBS, EBS and FBS series screw blowers

Kaeser Compressors’ energy-saving, low-pressure screw blowers are now available in three sizes. Featuring an integrated Sigma 2 Controller, optimum performance is ensured at all times and helps provide a dependable supply of compressed air.

The DBS, EBS and FBS series screw blowers are said to be up to 35% more efficient compared to conventional rotary blowers. The rotors are uncoated so users can be assured that their efficiency remains intact even after years of use. The data provided for the effective total energy consumption and usable flow capacity corresponds precisely to the machines’ actual performance.

For optimal performance, the Sigma Control 2 controller provides continuous and comprehensive monitoring and allows straightforward connection of each machine to a communications network. ‘Traffic light’ LED indicators show operational status at a glance. Along with plain text display, 30 selectable languages and soft-touch keys with icons, the controller offers fully automated monitoring and control.

Where multiple blowers are being used, additional optimisation can be achieved by incorporating the Sigma Air Manager 4.0 (SAM 4.0) master controller. Due to its high level of data integration and multiple interface options, it can be easily integrated into advanced production, building and energy management systems, as well as Industry 4.0 environments.

The screw blowers deliver flow rates from 6 to 67 m³/min with a pressure differential up to 1.1 bar and drive powers ranging from 22 to 110 kW. Sectors such as the food and beverage, pharmaceutical, chemical, pulp and paper, textile and construction materials industries, along with applications such as wastewater treatment, pneumatic conveying systems and power generation, can benefit from the screw blower technology.
