[2] Although the first commercial application of a fluid injected rotary-screw compressor was accomplished by Swedish industrial manufacturer Atlas Copco in 1957, it was Sullair's founding president, Don Hoodes, that introduced the technology to the U.S. domestic market in 1966.

[3] Hoodes purchased the use of the technology from Swedish firm Svenska Rotor Maskiner, whose retired chief engineer, Alf Lysholm, invented the twin-screw compressor in 1934 while developing gas turbines.
