Co2 Cylinders Pneumatic Psi

In summary, CO2 cannot be used in pneumatic cylinders because it is a gas and cannot compress and expand like a liquid. It also has a lower pressure rating than other gases such as compressed air, making it unsuitable for use. Pneumatic cylinders are typically filled with compressed air because it has a higher pressure rating and is more effective in creating the necessary force. Other gases like nitrogen and oxygen can also be used, but they are not as commonly used as compressed air. It is not possible to convert a pneumatic cylinder to use CO2 instead of compressed air due to the specific design and components of the cylinder.

I have only found pneumatic cylinders for pressures up to 450 PSI. Why do they not make them for higher pressures?

How were you planning to stop them at the ends of their strokes? You likewise have a problem with supplying compressed inert gas (air turns lubricants on seals into a fire/explosion hazard).

1. Why can't CO2 be used in pneumatic cylinders?

CO2 cannot be used in pneumatic cylinders because it is a gas at standard temperature and pressure, meaning it does not have the ability to compress and expand like a liquid. This is necessary for the functioning of a pneumatic cylinder.

2. Can CO2 be pressurized to create enough force for a pneumatic cylinder?

No, CO2 cannot be pressurized to create enough force for a pneumatic cylinder. CO2 has a lower pressure rating than other gases such as compressed air, making it unsuitable for use in pneumatic cylinders.

3. Why are pneumatic cylinders typically filled with compressed air instead of CO2?

Pneumatic cylinders are typically filled with compressed air instead of CO2 because compressed air has a higher pressure rating and can effectively create the force needed for a pneumatic cylinder to function.

4. Are there any other gases that can be used in pneumatic cylinders besides compressed air?

Yes, there are other gases that can be used in pneumatic cylinders, such as nitrogen and oxygen. However, these gases also have higher pressure ratings than CO2 and are more commonly used in industrial applications.

5. Is it possible to convert a pneumatic cylinder to use CO2 instead of compressed air?

No, it is not possible to convert a pneumatic cylinder to use CO2 instead of compressed air. The design and components of a pneumatic cylinder are specifically made to work with compressed air, and changing the gas used would require significant modifications to the cylinder's structure.
