Oil Mist, Oil Smoke
Oil mist eliminator, oil mist filter
At high manufacturing- and processing-speeds in the metalworking industry, the cooling and lubrication of the workpiece or the tool, as well as the removal of the metal cutting is urgent necessary. Not only specially developed emulsions, cooling lubricants, but also oils are used. Reasons for the formation of the oil mist are the rapid rotational movements during the machining process, which causes the oil to be thrown in the work space. Thus, fine oil droplets form which connect with the ambient air. (Under certain circumstances even an ignitable oil-air mixture can arise!) The workpiece is subjected to high thermal stresses during the machining process. The cooling of the workpiece evaporates the oil to oil steam or oil mist, and at the same time burns a small amount of oil and creates additional oil smoke. If the oil mist reaches the atmosphere of the halls, an oil film will accumulate over the entire inventory over time.
In the case of oil steam or oil vapoure, the particle size is less than 1 μm, and can be inhaled but not coughed out. These particles settled in the leukocytes and thus present an increased risk of cancer. The oil smoke is an additional odor. E-filters can help in this area. Electrostatic filters or electrostatic oil mist separators can filter out up to 99% of the oil particles. Electrostatic air filters are particularly suitable for depositing very small particles (deposition up to 0.01 μm) and provide a separation efficiency of up to 99%. The filters suitable for this purpose are the filters of the elstar series.
