When it comes to home use air compressors, many of the models available are too small and too weak to be used for many more intense applications. For example, a lot of small household air compressors simply do not generate enough psi (pounds per square inch of pressure) or cfm (cubic feet per minute of air flow) to power larger pneumatic (air driven) tools like nail guns, large paint sprayers, or saws and grinders. For these kinds of applications, a more powerful compressor is required though you probably do not need a full industrial air compressor. This is where the 6 gallon air compressor may be the best bet.
The "6 gallon" in 6 gallon air compressor refers to the size of the storage tank built into the compressor. The storage tanks plays a number of important roles, not least of which is regulating the amount of pressure you are generating and using to prevent accidental overloads. The tank allows the motor to stop compressing air once the tank is full to capacity, allowing it to rest and improving the machine's longevity. The tanks also guarantee an even output of air, despite fluctuations stemming from the motor; that is, the flow of air out of a compressor with a tanks is always steady and stable, unlike tankless compressors.

Although the 6 gallon air compressor comes in many different varieties, most are fairly small and easily portable, usually weighing somewhere between thirty to fifty pounds. These are not compressors meant for the truck on your car or to be taken out on the trail, but are excellent for people using a number of pneumatic tools around their home or in small work areas. They are portable, but not too portable. Further, the 6 gallon compressor is almost always designed to be used around the home and as such is driven by an electrical motor, typically using about 120 volts.
In general the 6 gallon air compressor also does not use oil, which makes them a bit louder, much easier to maintain and operate around the home. Adding in oil includes adding an oil recycling system, and air/oil separator unit, and a myriad of other features, which would more or less defeat the purpose of a small, easy to use home air compressor. Since portability is a key factor, one will frequently find either a flat "pancake" shapped tank or a vertical one as opposed to more awkward horizontal tanks connected to a 6 gallon compressor.
The 6 gallon air compressor is more or less the top end of the small compressors built for home use. Most generate at least 100 psi and enough cfm to run most household tools or even a few smaller tools simultaneously. Most of the better models in fact generate 150 psi, but this might be a waste of energy if you do not really need that much pressure in the tank(s). In general, one can expect to pay somewhere between 0 and 0 for a good quality 6 gallon compressor, though this price may come down as more and more of these small compressors enter the market.
