Cost Analysis CO2 Compressor Conventional Rotary Compressor for AC Motor Cylinder Oil Parts and materials used for CO2 compressor are almost same as those for conventional HFC or HCFC rotary compressor for AC. If the production quantity of CO2 compressors is closer to that of the conventional rotary compressors for AC, the incremental cost of CO2 compressor will ultimately become the difference of material usage.
