When choosing an air compressor, its important to consider the air pressure, configuration, and air capacity, as well as the CFM (cubic feet per minute) requirements of your air-powered tools. Here are some steps to help you determine the right size air compressor for your needs:
-
Determine the CFM requirements of your air-powered tools. Check the highest value CFM and PSI of your tools and multiply the CFM by about 1.5 to get the best margin CFM required for better and safe use.
-
Find an air compressor that meets the CFM requirements of your tools. Choose a model that exceeds these requirements by 10-20% .
-
Consider the air pressure requirements of your tools. Most air compressors are rated between 100 PSI to 175 PSI, so choose a compressor that provides about 20% more PSI than whats needed.
-
Consider the configuration and air capacity of the compressor. Reciprocating compressors are well-suited for intermittent use, while rotary screw compressors are designed to operate continuously and offer higher capacities.
-
Consider the duty cycle of the compressor. For large teams and industrial-scale equipment, aim for a duty cycle of 75% and above. Small crews and hobbyists can aim for a duty cycle of 50% or less.
-
Choose a compressor with a large enough tank to power your tools for extended periods. Usually, 10-20 gallons will suffice.
-
Pick the smallest possible model that meets these requirements to simplify transport and storage.
Remember that physical size is not the key factor to consider when purchasing an air compressor. A larger compressor isnt necessarily a more powerful one. Instead, evaluate your needs based on the factors listed above to determine the right size air compressor for your needs.
