MSG® 2/3 Centrifugal Air & Gas Compressor MSG compressors are custom designed and built for individual customer needs for a variety of applications. Our MSG style compressors are manufactured with a highly engineered air flow components, designed for easy, low- cost installation and operation. Features MSG® Integrally Geared Centrifugal Compressors MSG (multi- stage geared) compressors offer outstanding design flexibility. MSG compressors are application engineered with numerous available configurations: • Flows from 70 to 3800 m3/ min (2500 to 135,000 CFM) • Input capacity to over 18,650 kW (25,000 hp) • Discharge pressures to 100 barg (1450 psig) Features Oil-Free Air and Gas • Prevents system contamination • Reducesthe potential for compressed air pipeline fires caused by oil carryover • No costly waste disposal associated with oilladen condensate • Eliminates the expense and maintenance of oil separation filters at the discharge High Reliability • MSG centrifugal compressors are designed to be extremely reliable due to: %æ Conservative high- quality gear design %æ Long-life pinion bearing design %æ Thrust loads abs
