At this point, flow is choked because further reduction in system pressure does not result in additional air delivery. one that size will power many air tools you can spray many things it will be under heavy use when and of you want to spray a hole car but it is still able to do it. Look online for many more. Air flow rate data & instruments: this article defines air flow rate or cubic feet per minute (CFM) as the term is used to describe building air conditioners, heating systems, or building air movement rates. Types of Air Compressors. Altitude Effect On Air Compressor - posted in Industrial Professionals: For a given compressed air flow in terms of Nm3/h or scfm, will more power be required for an air compressor at an altitude of 1500 m. compressor pressure ratio, for different temperature ratios , is shown in Figure 3. Features Include: Flow rate: 72 LPM. 6 SCFM at 90 PSI, you can expect maximum air pressure, longer tool run times, and a quick recovery time. With a class-leading flow rate, this compressor has been designed for Air Locker® activation (on-board model), fast tire inflation, and a range of other functions whether they be for work or play. Flow is shown on the X-axis and head on the Y-axis. Compressor characteristic is the curve to show the behaviour of fluid, like change in pressure, temperature, entropy, flow rate etc. com gives you an overview of the different types of air compressors, common air compressor brands, and the average air compressor rental rates. The following chart is a good reference to determine your nozzle/pressure v/s compressor requirements for sandblasting. The statistic that you should be looking at when choosing an air compressor for your blast cabinet is the CFM, or cubic feet per minute. Two types of air compressors are commonly available for rent. If your air compressor is too small for the cabinet, it won't propel the blast media with enough force to strip, clean, or finish a surface. It depends where you are measuring the flow rate.
