With power ratings from 15 to 37 kW and flow rates from 4 to 22.5 cubic meters per minute, they are currently the most efficient screw blowers available, the company maintains. They are reportedly up to 35 percent more efficient than conventional rotary blowers and provide energy savings in the double-digit range compared with commonly available screw and turbo blowers. The blowers are seen as especially suitable for water treatment applications. Two different versions are available to meet the needs of such plants that require pressures of 400 or 650 mbar. The new machines are billed as particularly quiet, with sound levels in primary applications said not to exceed 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 also be installed side by side.
