It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure. A 50/50 duty cycle compressor is designed to run 50 percent of the time, while a 75/25 duty cycle compressor is designed to run 75 percent of the time. Definition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa). Together, they indicate the maximum air volume and pressure produced by an air compressor to power air tools.Ĭompressors with higher cfm ratings provide more air, which makes them more practical for larger jobs. PSI and CFM are often used as performance specifications for air compressors. PSI measures pressure, while CFM measures volume. The difference between PSI and CFM are what they measure. 1 cubic meter/second is equal to 3600 cubic m/ hr, or 2118.8799727597 cfm.Īlso asked, what is the relationship between CFM and PSI? You can view more details on each measurement unit: cubic m/ hr or cfm The SI derived unit for volume flow rate is the cubic meter/second. GE Druck DPI 610 DPI610S-PC-50PSIA Intrinsically Safe Pneumatic Calibrator, 0 to 50 psi (0 to 3.5 bar), Absolute The GE Druck DPI610S-PC-50PSIA Intrinsically Safe Pneumatic Calibrator is a self-contained, battery powered package that contains a pressure generator, fine pressure control, output measurement capabilities, as well as facilities. We assume you are converting between cubic metre/ hour and cubic foot/minute.

Secondly, how do you convert m3h to CFM? The answer is 1.69901082. George’s Mitsubishi Evolution is back at the track this time on high boost setting. It is completely compressor dependent, thus as William said, the only table would be for a given compressor. The relationship between CFM and PSI has nothing to do with ideal gas equations or the pressure volume relationship. The pressure just “pushes” the air out, and with half the “push” you get half the air flow. if you get 8 CFM at 120 psi, you will get 4 CFM at 60 PSI. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. 50 psi (3.4 bar or 345 kPa) D: 8-ply: 65 psi (4.5 bar or 448 kPa) E: 10-ply: 80 psi (5.5 bar or 552 kPa) F: 12-ply: 95 psi (6.6 bar or 655 kPa) G: 14-ply: 110 psi (7.6 bar or 758 kPa) The tire load range or for short tire ply rating recognizes the most extreme burden the tire can convey at its predetermined air pressure.
The relationship between CFM and PSI is just linear. For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757.
