Whether you are a beginner or a seasoned user, this guide will provide you with all the necessary information before you purchase an air compressor. So, let us start exploring and find the perfect air compressor for you!

What is Air Compressor?

Air compressors are incredibly useful tools to have in your possession. They are able to inflate tires, drive nail guns, and facilitate the use of other tools that require air pressure in order to function.

Air Compressor Types

Inflator – This is the most compact and weightless option. Generally, this wouldn’t be considered a compressor, as it does not pressurize air. Inflators do not have a storage container, thus they are constantly providing air. They are ideal for sports gear, minor inflation, and saving in the vehicle in case of a flat tire.

Piston Type Compressor – The tank contains air that is pressed down to a certain level. When that pressure point is reached, the motor will turn off. When the air inside the storage tank is used, the motor will start again and fill it back up with compressed air.

Single Stage Compressor – A single cylinder is used to compress the air which is then stored in a tank. These tanks are suitable for domestic use.

Two Stage Compressor – These machines have two cylinders that pump air into a container. The first one squeezes the air and passes it to the second one, which compresses it even further before sending it to the storage container. These are commonly used in professional settings, and they are designed to handle long-term usage.

Did you know? In the late 1700s, George Medhurst from England developed the initial motor-driven air compression device, which was mainly implemented in the mining sector.

When purchasing a compressor, there are particular components one should take into account

Horse Power – To create compression, the motor needs to generate energy. Generally speaking, the more powerful the engine, the higher the pressure of the compressor.

Compressor Storage Tank – The capacity of the storage tank for pressurized air is measured in gallons. Tanks with a greater capacity can store more compressed air at a higher pressure. Before purchasing a compressor, it is important to identify the tools to be used and their PSI ratings, to ensure the compressor is compatible with the tools.


Oil Free Compressors – The bearings are enclosed, so it is not necessary to lubricate them, which makes them ideal for home use.

Oil Lubricated Compressors – It is necessary to regularly switch out and replenish the oil when it’s being used in an industrial setting.

Power Supply

Electric – This is suitable for a variety of uses.

Cordless – Ideal for projects that require limited resources.

Gas – Consider obtaining a gas compressor if you are going to use it for something that does not have electricity. Gas compressors generate a considerable amount of energy.


What is an air compressor good for?

1. Operating pneumatically powered tools: Compressors are often employed to provide the force for pneumatic tools like nailers, wrenches that deliver impacts, guns that spray, and sanders. These implements are generally more lightweight and effective than electric ones and are usually used in construction, automotive maintenance, and carpentry.
2. Inflating tires: Air compressors can be used to inflate tires quickly and easily. They are often found in gas stations and auto repair shops, and many people also have them in their homes or garages for this purpose.
3. Cleaning: Air compressors can be used to blow dust and debris off surfaces or to clean hard-to-reach areas such as gutters or crevices. They are often used in industrial and manufacturing settings to clean machinery and equipment.
4. Spray painting: Air compressors can be used to power spray guns for painting cars, furniture, and other objects. This method provides a smooth, even coat of paint that is difficult to achieve with a brush or roller.
5. Powering airbrushes: Air compressors can also be used to power airbrushes for creating detailed artwork, body painting, or makeup application.

How big of an air compressor do I need for home use?

When it comes to a garage located in your residence, an air compressor with a capacity ranging from 6 to 24 litters should be sufficient.

What should you not do with an air compressor?

Never ever utilize your air compressor to get rid of dust or dirt on humans or animals. The forceful air from an air compressor has the potential to cause serious harm to your skin, eyes, and ears. These injuries can be life-threatening and must not be disregarded in any way.
