Lets plug these numbers into our equation: Flow Rate Conversion Table About Flow Rate Conversions Design calculations have been made using the following unit convention factors to maintain design consistency. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in or lbf/in) is a unit of pressure or of stress based on avoirdupois units. Pressure varies inversely with SCFM, so if your PSI is 90, your SCFM will be lower than if your PSI is 50. Consequently, the SCFM rating of a given machine will be a higher number than its CFM counterpart.

No matter your mobile air compressor application, big or small, its helpful to understand at least some of the science behind an air compressor system. Compressors that have high flow rate, such as 200 CFM, are ideal for larger applications such as HVAC systems while small, mobile compressors that deliver around 2 CFM are better suited for less demanding applications, such as pneumatic power tools. } Another way to think of this is in terms of the compressors output ability. In this example, NCMH = 100 x 1.5569 = 155.69 NCMH. Each supply of newly pressurized air that comes through the airend will inevitably lose some of its pressure once ambient factors take hold, like atmospheric pressure. 0000006238 00000 n
So as we do the math we solve for 11.04 SCFM @ 60 PSIG from a device that was shown to consume 14 SCFM @ 80 PSIG. 6 48
Most compressors for home use have tanks ranging in size from 1 gallon to 10 gallons. As you lower the PSI output, CFM increases. The SCFM is probably your most useful measure for this information. A duty cycle is a term meant to describe how long it takes a compressor to run compared to the total time it takes to complete an entire cycle of running and resting. A compressor thats rated for 3.0 CFM @ 90 PSI provides 3 cubic feet per minute at 90 pounds per square inch. It is measured using a pressure gauge attached to the compressor. window.open(url, "_blank"); To determine FAD, measurements must be made of the ambient pressure, humidity and temperature present at the air inlet of the machine. 0000034591 00000 n
