How Does An Air Compressor Tank Work

An air compressor works by using air pressure to compress the air inside the tank. This compressed air is then used to drive a variety of tools, including Piston Engines and Compressors. The tank in an air compressor system stores this compressed gas until it’s needed.

When the tool needs more compressed air, the valve on top of the tank releases it into the engine or pump. Air pressure is what drives an air compressor system and it comes from two places: atmospheric pressure (the weight of the atmosphere above you) and your compressor’s air pressure.

Atmospheric pressure is what pushes air down in the atmosphere and your compressor’s air pressure will be higher than atmospheric pressure because of the machinery inside of the compressor.

An air compressor tank is a vital component of air compressors used in industries like mining and farming. It is the storage tank that contains compressed air, which is fed to the compressor. A tank contains air under pressure and is made of metal or other tough material. It has an inlet valve, pressure gauge, and air hose connections.

A compressed air tank has many different parts that are interconnected to make a working system for the compressed air. Some of these parts include the tank’s body, valve, valve seat, pressure gauge, air hose connector, and so on.

History Of Air Compressors

History Of Air Compressors

Air compressors have a long history dating back to the early years of human civilization. Men and women of that era used their lungs to create compressed air to stoke fires as an alternative to using combustible fuels.

The first mechanical air compressors were developed by the Chinese in the 3rd century BC. John Smeaton of Great Britain is credited with inventing the air compressor in 1762. He devised a way to compress air using a water wheel and a piston.

However, Wilkinson and Medhurst made further innovations in the 18th century in the area of air compression technology. Unlike Smeaton’s design, their air compressors could produce compressed air using atmospheric pressure alone without using external energy such as water or wind.

In the last 50 years, air compressors have undergone significant technological advancements that have led to air compressors of today being more powerful, efficient, and versatile than ever before.

Air Compressor Basics

Air Compressor Basics

An air compressor is a machine that stores atmospheric air under pressure and converts potential energy into kinetic energy. This is used in many applications, such as powering nail guns and paint sprayers. Air compressors are composed of a variety of components, such as a regulator, pressure gauge, air filter, and motor.

Regular maintenance is important for air compressors to keep them running properly. Different models come in sizes and power outputs, from 1 hp to large industrial models. Regularly checking your air compressor for signs of wear and tear can help ensure its optimal performance and lifespan.

The Mechanics Of An Air Compressor

Air compressors use an electric or gas motor, pump, inlet/outlet valve, and air storage tank to draw in and compress air, creating potential energy. The inlet valve regulates the pressure of air entering the tank.

The motor rotates the pump, which rotates the scroll-type compressor. This type of compressor uses pistons, screws, and scrolls to reduce the volume of air as pressure rises inside the tank.

The duty cycle of an air compressor is complete when the maximum pressure is reached inside the tank and the compressor turns back on when the pressure lowers below a specific number. An air compressor is a vital part of any industrial facility that needs a source of compressed air for various applications or processes.

Reciprocating Piston Compressors

Reciprocating Piston Compressors

Reciprocating piston compressors operate similarly to a combustion engine, using a crankshaft rod to move the piston and compress air. They are one of the most common types of air compressors, using either one or two pistons depending on the model.

Single-stage compressors use one piston, while two-stage compressors use two pistons, resulting in higher air pressure. Positive-displacement compressors are another type of air compressor that forces air into a chamber and then release it through a port or valve.

These compressors are typically more powerful than single-stage or two-stage compressors, but they can be more expensive and have a higher energy consumption rate. Overall, reciprocating piston air compressors are versatile and can be used in a variety of applications ranging from industrial to household usage.

Rotary-Screw Compressors

Rotary-screw compressors are a type of air compressor that uses two helical screws to decrease the volume of air in a cylinder when they turn. These compressors are typically used in industrial applications where they must provide pressure to air tools that demand higher pressure.

They are also quieter and more reliable than other compressor types, as they have fewer moving parts and require fewer maintenance procedures. Additionally, rotary-screw compressors are oil-sealed and have a higher compression ratio than other compressor types, which makes them suitable for applications that require high pressures with little storage space.

However, some air compressor designs feature piston compressors instead of the rotary-screw type. These compressors are more efficient but require more maintenance and energy consumption.

Scroll Compressors

A scroll compressor is an air compressor that uses a design of two interwoven metal pieces to create a vacuum. It is known for its efficient, oil-free, and quiet operation. The scroll design uses two spiral-shaped circular pieces that rotate around one another to compress incoming air.

In this way, the compressor can quickly and efficiently deliver compressed air at high pressure. Scroll compressors are a type of positive displacement compressor, which means they use the pressure of compressed air to move other components in the system.

This makes them more efficient than other types of compressors. These compressors are commonly used in applications where compressed air needs to be rapidly transported or transferred from one location to another, such as in the building industry and manufacturing facilities.

How To Use A Portable Compressed Air Tank

A compressed air tank is a pressure vessel that holds air compressed under pressure and releases it through a valve. It can be of various sizes, ranging from two gallons to 30 gallons, and is carried or has wheels for mobility. The compressed air tank is used in applications using the blow-off tip, such as filling tires on cars, bicycles, trailers, ATVs, etc.

A portable compressed air tank is more useful in the field than portable air compressors due to their relatively lightweight and large size. They are easy to carry and use. The tank can be filled using an air compressor or by using a valve attachment with a hose. After using a compressed air tank, it should be properly cleaned and stored in a dry place to ensure its longevity.


There are several air compressor types that you can choose from depending on your specific needs. Each type of air compressor tank has characteristics that make it suitable for a wide range of applications. Knowing the basics of using air compressors and the variation in air tank types can help you get more value out of compressed air. Ultimately, the decision boils down to your requirements and budget.

Frequently Asked Questions

1.How Does A Compressed Air Tank Work?

Ans: A compressed air tank works by using air compressed under pressure to do work. When the tank is needed, the valve opens and the compressed air rushes out in a powerful beam.

2.Are You Supposed To Drain The Air Compressor Tank?

Ans: Air compressors should be drained after each use to avoid rot and air compressor explosions.

  • Draining the air compressor tank should be done before adding on additional tanks.
  • Zero air-loss condensate drains can be used to automatically control drainage.
  • Leaks from the oil fill tube can be caused by worn piston seals and should be fixed immediately.

3.Will A 5-Gallon Air Tank Fill A Tire?

Ans: A tank is not necessary to fill a tire as air compressors with Lithium-Ion batteries are available and can do the job without the use of a tank. Compressors with tanks can store compressed air at higher pressures, but they will not allow for tires to be inflated any faster.

4.What Is Inside An Air Compressor Tank?

Ans: An air receiver tank, also known as a compressed air storage tank, is a pressure vessel that holds compressed air. This tank stores compressed air that can be used for short, high-demand events such as construction or the event of a power outage.
