Air Logic Division of Knapp Mfg., Inc. was created in 1975 when the Air Logic product line was purchased from Johnson Controls. Before the purchase, the Knapp family business had been a key supplier of Air Logic molded components. Air Logic’s parent company was started by Fred Knapp, a metal engraver with decades of experience who decided to open a shop in his basement back in 1935. Joined by his three sons, they launched the Fred Knapp Engraving Co. in 1945, specializing in steel marking stamps, engraved signs, and dials. The company quickly expanded and diversified, in 1955 the business moved to its current location and added tooling and injection molding services to their engraving capabilities. Injection molding of small components with precision orifices eventually became a core competency at the business. In 1975, Knapp acquired the Fluidic Division of Johnson Controls in Milwaukee, Wisconsin, which became known as Air Logic.
