A few years ago I got a letter from my cousin back in Florida. He is a portable air compressor too. He works with a roofing company contractor. I could never do that sort of work because I am too big. Luckily, my cousin is just the right size and can be used up on the roof. I guess the workers just take him right on up and secure him to their roofing jacks. This seems dangerous to me, but different strokes for different folks.
This kind is suitable for people on the go or who travel. You never have to go through the tedious task of having to find a vehicle big enough to carry your compressor wherever you wanted to go.
A portable air compressor comes in many shapes and sizes. We are only truly portable if we don't get too big. As long as we can be moved around easily and used where needed then we are considered truly portable. Once we get too big, then we are relegated to shop work and other stationary jobs. I pity these poor fools. It would be boring to just sit in one shop all day. I like getting out and seeing different places and meeting different people. I think it keeps me young.
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.
An important factor is also the factor of oil. The oil is used for lubrication of moving parts of the compressor, but it also has some side effects. For example, traces of oil can be found in the tubes that deliver air to your airbrush tool, so it can be mixed with paint. This problem is more pronounced if the compressor is older. One possible solution is to purchase an oil free air compressor.
Armed with a bit of information, and knowing my husband and how he will use his compressor, I was soon on my way to purchasing the right Powermate Coleman air compressor for him for Christmas. I hope this information will help you too!
