About SullairFor more than 50 years, Sullair has been on the leading edge of compressed air solutions. We wereone of the first to execute rotary screw technology in our air compressors. And our machines arefamous all over the world for their legendary durability. As the industry moves forward, Sullair will alwaysbe at the forefront with quality people, innovative solutions, and air compressors that are built to last.Sullair was founded in Michigan City, Indiana in 1965, and has since expanded with a broad internationalnetwork to serve customers in every corner of the globe. Sullair has offices in Chicago and manufacturingfacilities in the United States and China — all ISO 9001 certified to assure the highest quality standardsin manufacturing. In addition, the Sullair Suzhou facility is ISO14001 and OHSAS 18001 certified.Sullair is a Hitachi Group Company.SullairCapabilitiesSULLAIR LEADERSHIPSTATISTICAL PROCESS CONTROLSince 1965, Sullair has been recognized around the world as an innovatorand a leader in rotary screw compression and vacuum technology. Formore than 50 years, Sullair has designed and manufactured its ownrotors and air end assemblies in Michigan City, Indiana.The Sullair Statistical Process Control (SPC) system monitors rotor qualitystandards to assure consistent compressor and vacuum performance.The legendary rotary screw design sets the industry standardsand delivers the quality and reliability one expects from a leader.Underlying leadership at Sullair is a dedication to excellence and acommitment to innovation. Sullair constantly explores new ideas andseeks new ways to meet the industry’s need for increasingly energyefficient compressed air and vacuum solutions.SULLAIR TECHNOLOGYUtilizing the most modern technologies, equipment and advancedmanufacturing techniques, Sullair designs, manufactures, assembles, andtests the most innovative compressed air and vacuum products in theindustry.

Axial air inlet avoids preheating inlet air for further savings.4
