SCFM, along with CFM and PSI, are acronyms that you should know when you shop for an air compressor because understanding these measurements will help you make the right choice. Trident Compressed Air Ltd. In general, high-powered pneumatic tools attached to large, stationary air compressors will require a CFM rating of 10 or higher, whereas tools attached to portable compressors may only require five-or-under CFM. } With both practical and theoretical experience in pneumatics and hydraulics, I'm putting my knowledge to work - and working my grey-matter through my research, assistance and publishing work here at About Air Compressors. electric air compressor (model: C303H) has 6.8 CFM at 40 PSI, and 5.1 CFM at 90 PSI, but Id like to know what CFM it has at 23 PSI to utilize a DeVilbiss Finishline 4 HVLP paint gun (model: FLG-670), which requires a minimum of 13 CFM at that PSI to run properly (per manufacturer specifications). I just installed a zero air generator and it calls for me suppling 5 SCFM out of it. This is also called artificial demand and can result in significant energy loss with high energy cost. PRESSURE. Air pressure is measured in pounds per square inch or PSI, while air flow (also referred to as volume) is measured in cubic feet per minute or CFM. So how are SCFM and CFM different? Google use cookies for serving our ads and handling visitor statistics. For help finding the right air compressors to buy for your business or a free estimate on any of our products,contact us today. Pressure varies inversely with SCFM, so if your PSI is 90, your SCFM will be lower than if your PSI is 50. 0000029199 00000 n 6 48 If you intend to run two or more pneumatic air tools simultaneously from a single compressor, add up the total SCFM of all the tools and multiply that number by 1.5 to determine the necessary SCFM for your next air compressor.

If you then adjust the air pressure regulator to 45 PSI and the air in the tank is once again always kept between 90-130 PSI For applications where a continuous flow of air is needed, a larger tank size will be more beneficial. 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. P1 = absolute initial atmospheric pressure (psi) (14.7 psi at sea level) P2 = absolute final pressure after compression (psi) V = volume of air at atmospheric pressure - standard or free air (scfm, ft3/min) adiabatic compression (or expansion) takes place without transmission of heat Sponsored Links Related Topics Since you likely wont be operating your compressor under these ideal conditions all the time, the actual CFM will vary from the SCFM.

Manage Settings As a measurable value, a compressors CFM rating will always be a lower number than the SCFM rating because the former value is measured at the point where the air supply is pressurized, usually at 90 PSI. For flow through a tube, the rate is a constant. Although, if youre looking to save money on energy costs, you could benefit from a lower HP compressor, as they tend to use less energy than compressors with higher HP motors.
