This process is commonly used in pneumatic systems for various applications such as in industrial automation, robotics, and medical devices. The use of compressed air in cylinders provides a reliable and efficient way to control the movement and operation of various mechanical systems. **

We do not filter CO (carbon monoxide) from the air because it is a naturally occurring gas that is present in very low concentrations in the atmosphere. Additionally, carbon monoxide is not a major component of air pollution and is not typically a concern in outdoor air quality.
