You should know the importance of air compressors if you’re into home remodeling or any other industrial site jobs. Air compressors are prevalent and useful machines with broad applicability.
They can be used in different working places like a car wash, woodshop, auto body shop, medical and dental services, ski hills, and many more.
When you’re buying an air compressor, you need to choose the right one. More so, different designs and kinds of air compressors on the market will confuse you.
So, to choose the right one with a low budget, you need nothing but our recommendation. Here, we have compiled a list of the 5 air compressors to help you out.
How Do Air Compressors Work?
Air compressors function by forcing pressurized air into a container. The air then compels through the opening of the tank where the pressure builds up.
For example, take a gallon and fill it with air, then open it. You would notice that air will rush out with force.
When the balloon is opened, the compressed air released can be used as energy. These air compressors are powered by a motor that converts electrical energy or power into kinetic energy.
They work similarly to a combustion engine that uses a piston, valve, connecting rod, head, and crankshaft.
When the tank is filled with pressured air to its full capacity, the motor will be shut, and the pressured air will be reserved in the tank until it is used.
The ability of air compressors to store air with its tank makes it different from a pump. Compressed air in the tank can also power a wide range of tools such as sanders, impact wrenches, nailers, and paint sprayers.
After the air stored in the tank has been released, the container will be decompressed. Then from the lowest limit of the container, the compressor re-pressurizes, and resumes, generating potential energy within the tank, thereby fill it with air.
Types of Compressors
There are numerous types of compressors out there, and they can be categorized in a myriad of different ways. In this article, we will categorize air compressors in terms of pressure, designs, and functionality.In terms of pressure, there are three major types of compressors.
These include high-pressure compressors, medium-pressure compressor, and low-pressure compressors.
The high-pressure compressors produce more than 1,000 Pound per Square Inches, medium-pressure compressors produce 151 Pound per Square Inches to 1,000 Pound per Square Inches, and low-pressure compressors produce 150 Pound per Square Inches or less.
Secondly, in terms of designs and functionality, air compressors can be categorized into many groups. We are going to look at the common ones.
These include a two-stage reciprocating compressor, rotary-screw compressor, and rotary-air compressor (spiral lobe oil flooded screw).
Also, single-stage helical air is the most common rotary-air compressor. If you’re looking for an air compressor built for high capacity, then this is the best option for you.
Rotary screw air compressors and reciprocating air compressors are the most popular and used types of compressors. They are popular because they are efficient, sturdy, and durable.
