The development of the continuous-slot profile wire technology by Johnson in the early 1930s revolutionized the industry, and quickly became the industry standard for well screens around the world.
Today, operators continue to drill deeper & into more challenging formations & this revolutionary technology is being continuously advanced and improved upon, providing the best well screens for municipal, industrial, commercial, agricultural, domestic and environmental applications.
