Description
The new generation of breathing air compressor LW 700 ES II is characterized by its sturdy and powerful design.
The improved sound insulation is ideal for being used in commercial and sales areas, as well as in mixed residential and industrial buildings. A novel drainage system features a 10 litre condensate collection tank, as well as a highly efficient pre-separator unit which improves lifetime of the filter cartridge considerably. Innovative condensate valves also limit the pressure drops during condensation cycles to ensure enhanced profitability.
The industry-proven, new lubrication system, as well as reinforced compressor components are the main points of the optimized compressor block which allow to use the LW 700 ES II for continuous running and for being used in three-shift operations at breathing air and highpressure applications.
