Standard Cubic Feet of air per Minute.
Air Conditioning compressors always use in the home, it is small and cheap price, In generally, we think that air compressor is industrial air compressor, which this kind of air compressor use in factory and mining machinery, to compressed air.
Can only assume the question was "why do you use compressors for pneumatics?"...But if not, ignore this. If you didn't use a compressor, your circuit wouldn't do anything, the air would but incapable of pushing the cylinders, opening valves or doing anything.
You can calculate the amount of available air by the following: SCFavailable=Volume of tank(cf)x((P2-P1)/Patm) Volume=600 gal/(7.5 gal/cf) = 80 cu.ft. P2=Compressor High Set Point = 110 psi P1=System Pressure Requirement = 90 psi Patm= Depends on your location, but I'll assume 13.16 psig @ 3000' Available Air = 121.6 cu.ft. Divide by your calculated peak air consumption rate, I will assume 10 scfm. 121.6 cu.ft./10 scfm = ~ 12 minutes You can calculate the time of recovery for your system by dividing by the amount your compressor supply rate. If your air compressor is rated for 30 scfm @ 110 psi and you are continuously consuming 10 scfm while recovering at 30 scfm then take the available air and divide by the difference of your recovery rate and your consumption rate. In this case it would take 6 minutes to fill your tank. Your duty cycle for this example would be run time divided by total time or 6min/18min = 33% duty cycle so I would look for a 50% duty cycle rated compressor. Hope this helps.
air compressors work on simple principle of compressing the air at lower temperature. air being the only fluid having highest level of compressibility is subjected to compression either by piston, rotating screw or centrifugal effect in a sealed environment where heat is carried away regularly with the help of coolants. thus in a sequential process the air is compressed. generally the air is captivated in a cavity/space and this cavity/space is sequentially reduced in order to have compression effect and the resulting rise in temperature is taken away by coolants at regular heat thus finally resulting in compression of air.
It depends upon which type of compressor you are inquiring about. In general a compressor takes in air, compresses it within a tank and releases it in varying strengths determined by a valve.
Craftsman is a good brand of air compressor, it has good hp rating, puts out sufficient scfm. Good warranty, and their products are made to last, as long as its used for that intended use.

SIC 3563 applies to AIR AND GAS COMPRESSORS.
Drills, Compressors, and jack hammers can all be used with air compressors. There are commercial versions of compressors also available.

Amerinca Standard manufactures their own compressors. They also manufacture compressors for other major manufactrures.
I have three Craftsman air compressors, and on all three, the tank is marked with DeVilbiss. I can't say who manufactures the COMPRESSOR portion, but the TANK comes from DeVilbiss, who also does make compressors.
