Function of an Air Compressor

With the wide variety of models available, it’s important that you know exactly what kind of air compressor to purchase that will accommodate your job. Air compressors usually go hand-in-hand with air tools and other machines. Depending on which machine you want to power, you have to choose the relevant air compressor.

The main function of this device is to convert power into energy, by the means of using pressurized air.

At Home: A small air compressor can be used around the house to pump up deflated motorcycle, vehicle, and bicycle tires. It can also be used with a variety of power tools to help with building a deck, patio, or shade.

Furthermore, it can be used with a tool that has the function of spraypainting larger walls in the house.  Use it as a light-duty leaf blower system.

Contractors: For business owners and contractors, air compressors can help with painting cars, changing tires of vehicles, building structures, and cleaning. Investing in a high-quality and durable air compressor will help you save time and money.

Industrial: For manufacturing companies, industrial-grade air compressors are the way to go.  They provide serious power that speeds up production.

How Does an Air Compressor Works?

It’s a simple device that consists of a compressor pump and an air tank. When switched on, the compressor pump uses voltage from an electrical socket to pump air into a tank. Inside the tank, the air is compressed at a high level.

When the air tank reaches the maximum air pressure, the compressor shuts off. The pressurized air, found in the air tank, can be released through an output port to a pneumatic tool. These tools pneumatic tools include paint sprayers, tire inflators, jackhammers, and air wrenches among many others.

Once the pressurized air inside the tank is depleted, the compressor motor starts up again to start adding air into the tank once more. Depending on the size of the air tank, the device will run a certain amount of time before it has to restart again.

Manufacturers who operate far away from power sources need bigger tanks.

Types of Air Compressors

There are a few types of different technology systems that drives the mechanics of air compressors.


Using a rotary screw system, air is squeezed through rotating screws into the air tank. Perfect for heavy-duty and longterm jobs. The rotary technology system doesn’t require much maintenance, as the internal parts are oil-sealed and doesn’t cause a lot of friction.


Most typically used, the reciprocating piston air compressor uses similar technology to that of a car’s engine. Pistons are driven by crankshafts in a forward and backward motion. This motion creates a vacuum that pushes air into the tank when extended and sucks the air out when retracting.

Reciprocating systems are usually much louder because the cylinders inside create a lot of friction. However, dual-piston and oil-less technology reduces noise and overheating.


Typically used in freezer and refrigerators, the scroll technology uses two pieces that are spiral-shaped. These two parts rotate around each other to create compressed air.

Perfect to be used in dentistry tools, food industry equipment, and electronics. Because they operate quietly while producing industry-standard clean air.

Gas or Electric Air Compressors

Electrical air compressors use an electrical socket as their main power source. They are also less expensive than their gas counterparts. Electrical air compressors are either fixed to a specific area or can be portable. They can’t be used with extension cords which makes the use of them in areas far away from electrical sockets difficult.

Gas-powered air compressors can be used independently using a gas tank as a power source. The main difference between the two, is that electrical air compressors have a generic on and off switch and a gas type doesn’t. This allows the power compressor to switch off automatically, once the maximum air pressure has been reached.

Gas air compressors are much more functional for heavy-duty jobs, whereas electrical air compressors are better for low to medium-duty jobs. It’s recommended that gas air compressors are used outside and never inside. Because they create indoor noise and gas fumes that can be hazardous to your health.

Best Brands

When you want your air compressor to last a long time, you need to consider investing in a well-known, high-quality brand. Here are our top three choices:


Tirewell is a China-based company that has reached high ratings over the last few years. They have a team of thirty highly qualified and dedicated designers and engineers, who help develop high-quality air compressor tire inflators.

Tirewell’s goal is to stay relevant by following automotive trends while creating ergonomically charged products. They focus on health and safety elements to create user-friendly devices.

Factors to Consider Before Buying an Air Compressor

It is clear that there are a lot of different kinds of technology that goes into an air compressor design. It’s important that you consider a few key factors before purchasing one. This will ensure that you buy the right air compressor for the job.

Here is a list of things you have to consider:

Horsepower (HP)

The more power the air compressor creates, the more powerful your tools can be. Horsepower is the indicator that determines the strength of the device. Regular house owned air compressors can produce 5 HP drawing 24 amps on a single-phase power outlet of 220 voltages.  Or on a 15 amp with a 110 voltage circuit.

When you look at HP, you have to consider the amp and voltages too. Also whether it’s gas or electric. A gas air compressor of 10 HP can produce as much compressed air as an electrical air compressor of 5 HP.

Cubic Feet Per Minute (CFM)

The volume of air that’s produced by an air compressor is rated in CFM. Certain tools need higher CFMs to function to their maximum capacity. Depending on which tool you want to use, you need a high CFM.

It’s recommended that you purchase an air compressor that produces 3-4 CFM per 1 HP at 90 PSI.

Air Pressure (PSI)

Air pressure is measured in PSI (Per Square Inch).  Common air tools need 90 PSI to run to maximum capacity. It’s important that you check the shut-off pressure. It should be high enough in order for the PSI to remain at 90. The first stage will build up to 90 PSI and the second to 175 PSI.

Small air compressors that are used for airbrush painting or other small hobbies, will have two-stage shut-off pressure of 125 PSI – 135 PSI.

Size of Air Tank

The air tank’s function is to store air not produce it. Therefore, it’s more important that you consider the size of the compressor motor and pump. If you have a big enough pump, you’ll never run out of compressed air.

Pump Power Drive (Direct or Belt)

Refer to the air compressor types mentioned above, the type is something you have to consider as this influences the noise, durability, and power.  Then you can decide between a direct or belt-driven pump.

Direct Drive: Is directly fastened to the motor itself. It turns at the exact same speed, spinning between 1,700-3400 RPM.

Belt Drive: Has a pulley system and drives between 900-1400 RPM. It has a larger oil capacity than that of a direct-driven pump. Because the belt is made from elastic, it can wear out over time and needs to be replaced.

Consider whether the motor is oiled or oil-free. Oiled devices are designed to run continuously and needs more maintenance. Whereas, oil-free devices are easier to maintain.

Durability and Longevity

Do check with the manufacturer what the life expectancy of an air compressor is. Investing in a high-quality brand that is durable will allow you to use the device for many years to come.

Consider the cost per use. If you are going to use the device on a regular basis, you should invest in a higher HP device than recommended by the tools you are going to use. An air compressor with a higher HP will most likely run 2 times longer as a lower HP device.


If you’ve ever been in an area where there is an air compressor, you’ll know that they can produce quite a bit of noise. Noise is measured in dBA (Decibels). Modern air compressors have a dBA of 40-90.  Small air compressors that are used by homeowners can produce as little as 40 dBA, whereas industrial-sized air compressors produce up to 90 dBA.

For hobbyists, a low dBA is recommended in the form of a quiet air compressor.  Unfortunately, there is no such thing as a completely silent air compressor. There are external measures you can apply to deafen most noise. You can install an intake silencer, isolate the compressor, and put a soundproof box around the compressor.

It’s important that users wear ear protection when they operate the device, as long exposure to high dBA can cause permanent ear damage.

Running Time

The running time is usually indicated in percentage. When a compressor has a 50% running time, it refers to the amount of time it can run within a 10-minute timeframe. Household compressors have a 50% duty cycle; Industrial compressors have at least a 75% duty cycle, with some heavy-duty industrial air compressors running at 100%.

Motor pumps can overheat when the percentage exceeds the duty cycle’s running time.
