One time we were working together on a small project that John had lined up for us. I was all powered up and fully charged with air pressure like normal. Everything seemed just fine. I heard the buzz of electric saws and saw the normal saw dust flying around. Then, all of a sudden, and without any warning, my breath was taken away from me in a gush! I thought I was going to die. John had accidentally set his circular saw down on my hose and cut into it. It alarmed me at first, but before long John had me all fixed up and back to work we went. Ah, such is the life of a portable air compressor.
Air output of a compressor is expressed in standard cubic feet per minute (SCFM) or just cubic feet per minute (CFM). Not all 5 HP compressors put out the same volume of air per minute. This is a function not only of motor horsepower but also the efficiency of the air compressor pump the motor is powering. The higher the CFM, the less your air compressor will have to cycle on and off to keep up with the demands you are putting on it. A small compressor pump on a huge tank will produce no more air than on a small tank. The only difference will be in the number of times the compressor cycles on an off each hour and the time it takes to recompress the tank on each cycle. In the final analysis, you need to pay attention to SCFM (or CFM) more than you do motor horsepower or tank size. Air flow is the end product of any compressor and the CFM must be sufficient to the job at hand.
Oil free systems are a bit more technical so sometimes are more expensive. Often they are louder than an oil lubed compressor, but the air delivered through one of these pumps is of a better quality. They are found for home use, and are great because they are low maintenance and start up quick in cold weather.
