Six tips for choosing an air compressor.Still wondering what this means for you? We’ve put together a helpful air tool consumption chart to help give you an idea of how many CFM you need to run your air tools. Air receiver tanks on service trucks can vary from 5 gallons to over 100 gallons. In some scenarios, air receiver tanks can help a lower CFM air compressor keep up with a higher CFM demand and can be a good strategy when you don’t want to invest in a higher CFM air compressor. Many air compressors require an air receiver tank-in fact, this is always the case with reciprocating air compressors, which need an air receiver tank and can only produce full air power until the tank runs out of stored air. You would likely need an air compressor that can reliably produce 90 CFM of air when choosing equipment.Īir receiver tanks are another factor you should consider when determining your CFM needs. If you use these tools simultaneously, you will add 30 CFM + 60 CFM for a total demand of 90 CFM. However, if you’re running multiple tools at the same time, you’ll need to combine the CFM requirements of each of the tools that will be running to determine your total CFM requirement.įor example, let’s say your team uses the same air compressor to power a ½” drill that requires 30 CFM and a grinder that requires 60 CFM. Running more than one tool at a time can be a highly efficient way to get things done, especially when you have two or more people working on a single job. Multiple ToolsĪnother common scenario that impacts CFM requirements is using multiple tools at once. If your application requires you to run air tools for an extended length of time, an air compressor with a 100% duty cycle is recommended so you can operate your tools continuously.īy contrast, tools only used intermittently may be able to get away with a less powerful air compressor that uses an air receiver tank, which may save you money. using it in quick bursts with short breaks in between use, allowing the air compressor to catch up?ĭo you use tools for lengthy periods? Or are your tools only used for a few seconds here and there? These are the types of questions you need to ask yourself when you determine your CFM needs.continuously holding the trigger down while you work, or.For example, if you’re using an impact wrench, are you: Intermittent UseĪir tools need a CFM that matches the manufacturer’s guidelines, but what air tool you have and how you use them matters. This article will help you better understand how many CFM you need to run your air tools. Your tools’ CFM requirements give you an idea of what you need your air compressor to do, but it’s not enough to match the air tool’s rating and the compressor’s rating 1:1. CFM represents the volume of air produced by your air compressor or required by your air tool. Jump To The Air Tool Chart Pneumatic Tool CFM RequirementsĮvery pneumatic tool is rated for CFM, or “Cubic Feet Per Minute”, and the same goes for air compressors. But before we get into the CFM consumption chart, let’s talk a little bit about why CFM matters to you… We’ve developed this helpful air tool consumption chart to help you find the air compressor that’s right for you. Too little CFM and you won’t be able to run your tools continuously-or at all-and too much CFM could mean you’ve overspent on your air compressor! It can be tough to know how many CFM you need in an air compressor to operate your air tools.
