It was the early 1950’s when an ingenious industrialist by the name of Arthur Cohen invented the Airpot dashpot.
A graduate of the Massachusetts Institute of Technology and subsequent founder of the Electric Regulator Corporation in 1945, Mr. Cohen invented, manufactured and successfully marketed a line of electromechanical voltage regulators which he named Reghom.
The unique design of the regulators required a dashpot with low friction, long life, and high reliability. Since no such device was commercially available at the time, Mr. Cohen designed one himself. To meet the demanding performance requirements of the Reghom, he employed a unique combination of materials for the dashpot: graphite and glass.
