Types of Air Compressors
There are two different types of air compressors to consider, and choosing the best one depends of the type of job you’ll be doing. Portable air compressors are best suited for smaller jobs at home and even at work, while stationary compressors are able to power larger automotive and manufacturing tools.
Air compressors are also separated into two distinct categories which include,
- Single stage air compressors are stationary and deliver maximum pounds per square inch (psi) of 150. This single step system works on only one piston and is ideal for powering nail guns, tire pumps, and for most of the other small air tools.
- Two stage air compressors are also stationary, but they use two pistons to compress and push out the air. The maximum psi ratings on these heavy duty air compressors ranges well over 150, and they are best suited for use in a machine shop or garage.
Advantages to Air Compressors
There are several advantages to using an air compressor to help power your tools, including the fact that they can help you save time and money. With a compressor you can work faster and use your tools longer, and there are several different types to choose from. Gasoline powered air compressors can go with you almost anywhere, while the electric compressors can help a project run more efficiently.
Whether you need a larger air compressor to power a nail framing gun on a larger construction site or a smaller model to simply inflate your car’s tires, they can make your job easier. With the advantage of having compressed air quickly do all of the work for you, there’ll finally be more time to spend on other projects.

Things to Consider
Air compressors can make many jobs easier and even shorter the time that it takes to finish them. Before you go out and buy an air compressor based on its size there are a few things that you need to consider,
- Moveable or stationary
- Power Source
- Ratings: PSI, SCFM, and horse power
- Type of Pump
Stationary or Moveable
One of the most important things you need to consider is whether or not you want to be able to easily move and transport your air compressor. The two main types of compressors are:
Portable compressors: This type of air compressor comes in several different sizes. The larger ones normally include wheels, so you can move them easily between different jobs. The smaller models are ideal for powering nail guns, and for inflating tires and they usually include a 2-6 gallon air tank. Larger air compressors can be used for projects in either a personal or commercial garage and can include air tanks ranging from 20-30 gallons.
Stationary compressors: These compressors are designed for powering tools in shops and garages. They are normally bolted to the floor, and can be wired into the building electrical outlet. Their tanks can range in from 60-80 gallons, and often include a small engine.
The Power Source
There are two main sources of power for air compressors, gasoline and electric. Gas powered air compressors should only be used outside, since they do emit poisonous fumes. They are normally used on construction sites, and by home remodelers. Electric air compressors can be used safely indoors with the smaller models using 110-120v and the larger ones with more than 2 hp needing a 220-224v outlet.
Now that you’ve decided on the type of air compressor you need, it is time to understand their performance ratings. One of the first things to look for is the compressor’s standard cubic feet per minute rating or SCFM. This will tell you how much air the compressor can deliver. If you are powering smaller tools a SCFM rating from 0-5 will be enough, while larger tools and longer use should have a SCFM of 10 or more.
You should also look at the compressor’s PSI rating. Smaller models are usually around 90psi, and the larger air compressors can be 150 psi or even higher. While this is not as important as how much compressed air a model can deliver, knowing the horsepower of the compressor can make a difference in choosing the best one. Smaller models for use around the house generally have 1.5-6.5 hp and can run off of a standard 110-120v electrical outlet and the compressors with 2hp or higher require a 220v outlet.
Tank and Type of Pump
The size of the tank on air compressors ranges from only 1 gallon all the way up to 80. The best sized tank will depend on how long you want to use the air compressor at a time.
Air compressor pumps can be divided into two distinct groups, single and two stages. Both of these types of pumps can have more than one cylinder operating, but the two stage pump can store more air in the tank so you can use it longer. Pumps are further categorized into oil and oil free, with the majority of the smaller and lighter air compressors using an oil free design.
Many air compressors come with additional features including safety shut off power switches and an air cooling system. Both of these can help to protect the motor and prolong the life of the compressor. Roll cages can help to protect the compressor on job sites and while traveling, and an ASME certification means that you are buying the best.
Like any other tool or piece of machinery, safety is always essential. While automatic power shut off switches and roll cages might protect the compressor, you still need to be concerned with your own safety especially when you are using it. Some key safety tips include;
- Always make sure you are using the right power source. Never to plug a 120v compressor into a 220 outlet or vice versa. Not only can this damage the machine, it can also cause a fire or electrocution.
- Never use an air compressor if it is being powered by a generator.
- Check to make sure you are never exceeding the recommended pressure for any tool that you are using.
- If you own oil based air compressors checking the oil level before starting it can help to prevent costly repairs.
- Familiarize yourself with the safety release valves on the compressor. They can be used to release extra pressure if it becomes too high.
Most air compressors are generally considered low maintenance, and need only a simple cleaning. Oil based air compressors do require regular oil changes and should be treated similarly to a car engine. Regardless of which type of air compressor you choose, they all promise to require little care and cleaning to last through any job you throw at them.
Choosing the best air compressor doesn’t have to be overwhelming and you can find the right one for your jobs and projects. The benefits of using an air compressor can range from saving you time and money, to simply helping you to prevent muscle fatigue. They are easy and safe to use, and now they are even quiet while still being powerful. Whether you choose a lightweight model for small projects around the house or a larger compressor for construction sites and garages, there is an air compressor that can help you get all of your jobs done.
