The compressor plays a crucial role in preparing the separated oxygen (O₂) for storage and use. After the oxygen is separated from methanol in the condenser, it enters the compressor, where it is pressurized to make it suitable for storage in oxygen tanks. The compressor works by reducing the volume of the oxygen gas, which increases its pressure. This is achieved using a system of pistons that compress the gas in stages to ensure efficient energy use. During compression, heat is generated, so the compressor is equipped with cooling systems to maintain optimal operating temperatures and prevent overheating. The high-pressure oxygen is then filtered to ensure it meets purity standards before being directed into storage tanks. By compressing the oxygen, the machine ensures a steady supply that can be safely stored and used in hospitals or other medical facilities.
