Oil Mist, oil Smoke
Oil mist separator, oil mist filter
Given the high speed of our production and process in the metalworking industry, the cooling and lubricating of the workpiece or tool as well as the removal of chips is imperative and necessary. We use specially-developed emulsions, cooling lubricants and oils.The reasons for the formation of the oil mist include the rapid rotational movements in the machining process, which causes the oil to be sprayed around in the workshop. Fine oil droplets form, which connect with the ambient air. (under certain circumstances, this can even result in an ignitable oil-air mixture!)
The workpiece is subject to high thermal stresses during the machining process. By cooling the workpiece, the oil evaporates to oil vapour or oil dust and at the same time a small part of the oil burns up. It also creates oil smoke.
Should the oil mist get into the air, over time an oil film will settle on all the items in the room.
The particle size of oil vapour or oil dust is less than 1 micron, and can be inhaled but cannot be coughed out. These particles settle in the alveoli and thus pose an increased risk of cancer.
The oil smoke causes an additional odour problem.
E-filters can provide a solution to this problem. Electrostatic filters and electrostatic oil mist separators can filter out up to 99% of oil particles. Electrostatic air filters are particularly suitable for the separation of very small particles (separation up to 0.01μm) and provide a separation efficiency of up to 99%.
The filters of the elstar series are suitable for this purpose.
