When determining what size air compressor is necessary for powering air tools, you’ll want to assess your tools’ specific air requirements and ensure the CFM requirements are compatible with the air compressor. You’ll also need to make sure the tools’ air pressure rating — measured in PSI — is matched to the compressor.
First, determine the CFM requirements for each air tool you plan to use. Next, add up the CFM of all tools and multiply the total by 1.5 to find your target CFM. Finally, look for air compressors that are designed to power all the tools you’ll use and ensure the model has multiple outlets.
The required CFM rating varies from project to project, but compressors in the 1,300 to 1,800 CFM range are typically chosen for larger construction, industrial and mining applications. For assistance choosing the best air tool compressor, reach out to a United Rentals expert.
