              How To Choose The Best Quiet 30-gallon Air Compressor?

              Maximum air pressure

              The maximum air pressure refers to the PSI (pounds per square inch) rating.

              It indicates how much air is present in the compressor. The PSI rating can range from 125 to 175 depending on the single-stage or two-stage model. You should choose the maximum air pressure that’s suitable for your jobs.

              Airflow rate

              This indicator shows the amount of air that the compressor can pump per minute. Measured in cubic feet per minute (CFM). As a rule of thumb, a higher rating means greater efficiency.

              The airflow rate of the air compressor must be higher than the intake rate of your tools, otherwise, the tools will stop in the middle of your work. To figure out the right CFM rating, you just need to multiply the maximum airflow rate of your tool by 4.

              Oil or Oil-free Tanks

              When shopping for an air compressor, you will have to pick one of the following types:

              • Oil-free tank: low maintenance, cheaper to run, quieter, less messy, more adaptable, and more environmentally friendly.
              • Oil tanks: more powerful and more durable.

              For a small capacity like 30 gallons, the more common choice is the oil-free tank that requires little to no maintenance. But the ultimate choice is yours.

              Noise

              A noisy machine can be very irritating when it operates. Therefore, you should pay attention to the noise level when choosing a compressor, go with 70 dB or lower.
