Kaeser Compressors is to showcase screw blowers from 15 kW for low rates from 8 to 22 m³/min, together with high-efficiency portable compressors at Wasser in Berlin
The new Kaeser DBS screw blower delivers unparalleled efficiency. The new Kaeser screw blowers are significantly more efficient than conventional rotary blowers and also provide substantial energy savings compared with many competing rotary and turbo blowers.
These benefits are made possible by the proven Sigma rotor technology used in the rotary screw compressor sector. Another key factor is the innovative non-slip direct drive with speed transmission integrated into the airend.
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 new blowers are exceptionally quiet, with sound levels in primary applications not exceeding 72 dB, which is equivalent to a modern vacuum cleaner.
They are designed for use over long duty cycles, including continuous operation, require little maintenance, and can be installed side by side, or even next to a wall. Upon request they can be delivered with an integrate, frequency converter or a star-delta starter.
The highly efficient DBS screw blowers will be amongst the many other highlights on show, which includes new road-going portable compressors. With such a wide range of innovative and trusted compressors, including the M13, M20 PE, M27 PE and M31 PE, Kaeser has the right compressor for any application. For instance, the M13 reliably drives compressed air hammers, drills, saws, screwdrivers and soil displacement hammers at a flow rate of 1.2 m³ of compressed air per minute at 7 bar pressure. And naturally there are also 10, 12 and 13 bar versions for jobs requiring higher pressures.
