The new generation of breathing air compressors LW 300 ES II / LW 450 ES II is characterized by its robust 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 includes 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 limits the pressure drop during the condensation drain cycle, the efficiency is thereby improved. L&W offers highest reliability at best value for money.
