The StarRotor (www.starrotor.com) C2S-01 is a small, lightweight, oil-free, compression system that provides 13 CFM (360 LPM) with a pressure ratio of 7.6. The measured motor electric power is 4.2 kW when compressing air at 1 atm and 20°C. The complete C2S-01 mass is 28 kg, which includes two gerotor compressor assemblies in a two-stage configuration, an electric motor, heat exchangers, filter, and water removal system. The gerotor assemblies comprise only 9.0 kg of the total compression system mass. The mass of the low-pressure gerotor is 6.9 kg, and the mass of the high-pressure gerotor is 2.1 kg. The C2S-01 compression system was developed for the U.S. Department of Energy to improve nuclear test detection capabilities, and is now available for other applications.
