Kaeser DBS series screw blowers

The DBS series screw blowers from Kaeser Compressors are designed to offer energy savings for wastewater treatment plants. They are available with power ratings from 15 to 37 kW and flow rates from 4 to 22.5 m³/min.

The DBS series are claimed to be up to 35% more efficient than conventional rotary blowers and to also provide energy savings in the double-digit range compared with many commonly available screw and turbo blowers.

These benefits are made possible by the Sigma Profile rotor technology used in Kaeser rotary screw compressors. Another key factor is the non-slip direct drive with speed transmission integrated into the screw compressor block, which delivers maximum speed with minimal transmission losses.

These screw blowers are especially well suited to municipal and industrial water treatment applications. Two different versions are available to meet the needs of water treatment plants requiring pressures of 400 or 650 mbar. The DBS blowers are quiet, with sound levels in primary applications not exceeding 72 dB, which is equivalent to a modern vacuum cleaner.

The low energy consumption of Kaeser screw blowers makes them suitable for supplying compressed air to water treatment plants. They are designed for use over long duty cycles, including continuous operation; require little maintenance; and can be installed side by side. Upon request they can be delivered with an integrated frequency converter or a star-delta starter.
