Electrostatic filter or electrostatic precipitator, also known as electrostatic precipitator, is a device that creates an electric field. As a result of oil erosion, you need oil purification. As a result of erosion, soluble and insoluble materials are created that have polar bonds and are less than one micron in size. These materials migrate to metal surfaces and form a thin and hard varnish deposit. The formation of this viscous deposit on parts in contact with oil is called varnish.
Electrostatic filters made by Nironmad Khorasan company are able to remove varnish with high efficiency without damaging the oil.
