The EM-8eIII collects mist generated in metal cutting processes. In this product, the charging electrode, which is the heart of the electrostatic precipitator, has been improved from the needle type to the brush type to increase the number discharges, thereby further extending the life of the electrode maintenance cycle. In addition, the concentration of suctioned mist has been increased to 200mg/m3 compared to 100mg/m3 of the old model.
