Oil-Free CO2 Compressor

Oil-Free CO2 Compressor is a high-performance solution designed for handling carbon dioxide (CO2) gas. It is widely used in CO2 gas recovery and supercritical fluid extraction applications. The compressor features a robust crankcase design capable of operating under specific intake negative pressure and positive intake pressure conditions. With a flow rate range of 30-80 Nm³/h and discharge pressures of 20 or 30 bar, it offers reliable and efficient performance. The unit is skid-mounted, air-cooled, and includes three compression stages with four gas cylinders. Key components are made from durable materials such as stainless steel for gas valves and pipes, cast iron for the case and crankshaft, and filled PTFE for piston and guide rings. The complete supply includes the main engine, motor, cooler, start cabinet, and necessary accessories.
