This is the second of two pages providing information on compressor sizing and compressor information.
Page one on compressor sizing is right here.
The manufacturer of that equipment should be able to provide the demand specifications for their machine. They know how many cylinders, the cycle rates, and they will provide the information about air consumption for their machine. Ask for it.
If you build that equipment yourself though, how much air will the air cylinders or air actuators on the new piece of equipment use?
This page has information about cylinder air consumption.
And, here's a useful air cylinder consumption calculator to help estimate each air actuators air consumption.
Always make sure you ask the compressor vendor what the expected actual CFM is for a particular model. It seems that the promised compressed air delivery from air compressors is similar to the estimated mileage figures you get for a new car. They are theoretical.
You also need to know what PSI that air flow will be as air delivery figures for lower air pressures is quite a bit higher than the delivery figures from the same air compressor at higher pressures.
Pages linked from the site map offer definitions for these various terms.
Industrial systems (actuators / air tools) often require about 90 PSI to work to their capacity. Some will require higher pressure, and some lower.
Again, some manufacturing plants will maintain a 20-30 PSI "safety margin" in extra compressed air pressure from the receiver, to help ensure that none of the plant equipment gets starved for air whether through pressure drop, leaks in the line, too much equipment being run at the same time, miscellaneous use of compressed air and so on.
Here is information about compressor water problems.
Help others, or let others help you size your air compressor.
