MECHATRONIC SOLUTION electrostatic oil cleaners use the principles of electrostatics (branch of physics that deals with forces exerted by a static or unchanging electric field upon charged objects) to remove particles and varnish contamination, as well as electrophoresis removal of naturally charged particles by electrostatic force and removal of a charge-neutral particle by gradient voltage field force

A particle with a positive charge is drawn toward a negative electrode within the system, while one with an inherent negative charge is drawn toward a grounded plate. A charge-neutral particle that either is alreadyhighly polar in nature, or is polarized by the non-uniform voltage field of the collector is drawn toward the area of the greatest field strength (folds of the collector pleats).
