Compressor sizing continuedThis is the second of two pages providing information to help you size the correct compressor for your use. How much compressed air for cylinders?How do you figure out air consumption of equipment? The manufacturer of that equipment will, and should, be able to provide the demand specifications for their machine. If you build that equipment yourself? How much air do air cylinders (actuators) use? Here's the page with detailed information on how to determine the Air Consumption of Air Cylinders . And, here's a useful air cylinder consumption calculator.Remember when you are determining the size of compressor you need the rule of thumb is that 1 HP (horsepower) is able to generate about 4 CFM of air flow at about 90 PSI. (PSI = pounds per square inch) for compressors over 10 HP in size, less than that for smaller DIY type air compressors. Still, always make sure you ask the compressor vendor what the expected actual CFM is for a particular model and type of compressor, and equally important, at what PSI that air flow will be. Flow is also a bit complicated. I measure compressed air in CFM increments, while others measure compressed air in SCFM. Careful about published specifications!Be careful when you are getting the specifications on compressors, as some manufacturers size their compressor discharge rates as if the unit was pumping free air. As air is compressed, the compressor has to work harder, as the pressure in the receiver increases. A compressor might show a CFM rating of 8 for example, but reading the fine print will tell you that it generates 8 CFM at a much lower pressure rating than the pressure you may require. Most industrial systems (actuators / air tools) require about 90 PSI to work to their capacity. Some will require much higher pressure, and some lower. Another rule of thumb: use an air regulator at the point of use to dial down the pressure and run the air equipment at the lowest possible pressure that gets the job done. You'll save a ton of energy costs if you do. Many industrial plants have air compressors generating air at 100-150 PSI in their air system. This allows for the inevitable over-line pressure drop , to ensure that they have sufficient compressed air pressure and volume at their end application to keep their equipment running satisfactorily. In other words, most 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. Compressing air generates water!Be aware that compressing air creates high humidity in the compressed air that turns into free flowing water in your compressed air tank and air lines.
