![]() ![]() PerformanceĪn air compressor’s working ability is shown by three key measurements: horsepower (hp), air pressure that’s shown in pounds per square inch (psi), and airflow capacity that’s shown in cubic feet per minute (cfm). Other noise-reducing solutions to watch for include cast-iron pistons, low rpms, and ASME-certified air tanks. ![]() The noise level, caused by friction in the motor, is affected by the pump design and the material of the components.ĭouble-piston, or duplex, pumps are more efficient and even less noisy because they move less to create the same amount of compressed air. To provide some context, 30 dB is equivalent to a whisper, 60 dB is the level of normal conversation, and a lawn mower engine is usually about 90 dB.Įntry-level single-piston compressor pumps are typically loud, whereas similarly designed units made with higher-quality materials create less noise. Most air compressor noise ratings range from 40 to 92 decibels (dB), but the best silent air compressor ratings are near 60 dB. They are available as wheeled and stationary configurations and have heavy-duty components for higher usage: framing, woodworking, and automotive use. Single stage compressors have a 10- to 20-gallon and larger tank with a vertical construction.Twin stack compressors have dual air tanks, are low maintenance, and are good for powering finish and trim tools.Hot dog compressors have a 6- to 10-gallon tank, are maintenance-free, and are good for operating small air tools.Pancake compressors have a 1- to 6-gallon tank, are maintenance-free, are good for inflating tires, and have limited use with small air tools.They are usually stored in a vehicle for inflating tires and toys. Inflators are small, lightweight, and tankless.There are five main types of compressors: inflator, pancake, hot dog, twin stack, and single stack. ![]() To get the greatest return on your investment, think about the ways you might use it and match the type of air compressor and its various specifications to those tasks. There are many factors to consider when deciding on an air compressor.
