Our customers include large multinational designers and manufacturers of inkjet printers, laser printers, thermal printers, and impact printers, as well as manufacturers of fax machines, paper handling devices, multifunction machines, and kiosks. Electro Static Technology is a division of Illinois Tool Works (ITW), a Fortune 500 company operating in 58 countries. We specialize in mitigating static charges, induced voltages, and random discharges on rotating shafts and moving surfaces, in all types of manufacturing equipment and machines. Our AEGIS® Shaft Grounding Ring product line protects VFD driven motors and prevents bearing fluting failure. Please see for more information on AEGIS shaft grounding protection. Design and application engineering are available to facilitate proper implementation of all of our discharge control devices.


Electro Static Technology Inc was founded in 1984. Our vision of passive static eliminators being utilized in high speed paper systems was innovative for a time that was dominated by powered systems. The first brush configuration was that of the V holder. A mere five years later, the two piece rigid configuration was introduced and the productivity more than quadrupled. In 1995, Electro Static Technology Inc. moved to its current location in Mechanic Falls. At the same time, EST developed a new manufacturing process today known as FLX™ for flexible brush. In 1999, Illinois Tool Works Inc (ITW), a multinational manufacturer of highly-engineered components and systems, acquired Electro Static Technology and made it a business unit of Electrostatics Division. In 2005, Electro Static Technology-ITW introduced the AEGIS Shaft Grounding Ring product line, and we continue to work on new applications of conductive microfiber-based technologies.
