Average Cfm For Air Tools

We include examples of manufacturer s air flow rate or cfm data for hvac equipment like air conditioners and furnaces.

Average cfm for air tools.

We ve put together a handy air tool consumption chart to help give you an idea of how many cfm you need to run your air tools. Air tool equipment average free air consumption cfm air bushing. Step 2 once all the air requirements have been determined total the cfm needed for the air compressor. The chart below includes some common air tools and their average cfm measurements.

Please note this is only a guide. Whether it s an impact gun grinder or breaker there are various ranges of air consumption each of these tools use. Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute cfm at 70 to 90 pounds per square inch psi whereas with larger tools connected to stationary systems the requirements usually exceed 10 cfm at 100 to 120 psi. Air tools are often rated as average cfm average cfm is typically based on a 25 duty cycle 15 seconds out of a min.

The real deciding factor in selecting the proper size air compressor is the cfm that it can produce. Reference this chart to determine what continuous cfm rating is required of your air compressor. In the example below we are sizing the compressor for a typical auto body shop. Here are some of the most common air tools and their average cfm requirements.

Air flow rate data. The majority of air tools operate in the 90 to 100 psi range and most air compressors from the smallest to the largest can easily produce this much pressure. Use the chart below to determine your average cfm requirements per tool or check with the manufacturer. We have put together an air tool consumption guide that includes common air tools in various sizes.

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. In this example that would be 80 cfm. Keep in mind that air tools are rated on a 25 duty cycle in use for 15 seconds out of every 60 seconds so for continuous use tools such as grinders you may want to multiple the cfm number by 4. A common question we get revolves around how much air a particular tool uses.
