What You Need to Know About Air Compressors?

Because compressors are somewhat complicated tools, we put together some information to help you out.

How Do Air Compressors Work?

Using a gasoline engine, or more often nowadays, an electric motor, these devices force more and more air into a tank of any size. Tanks can be as small as three gallons and larger than thirty gallons. This air now has a large amount of potential energy.

When the tank has reached maximum capacity in terms of pressure, the machine shuts off and the compressed air is stored within the tank until it needs to be used. This marks the main difference between a compressor and a pump.

The storage is crucial in eventually unleashing the kinetic energy of the stored air. The air itself can be utilized, but the kinetic energy that it contains can be an asset utilized as well for various purposes

Once all the air is released and the tank is depressurized, at its lowest limit the compressor resumes and re-pressurizes, filling the tank with air and creating potential energy again within the tank.

Types of Compressors

Compressors can be categorized in a myriad of different ways. In terms of pressure delivered, there are three types:

In another way, compressors can be categorized in terms of design and functionality. These classifications include: single-stage reciprocating compressor, two-stage reciprocating compressor, rotary-screw compressor, turbo compressor, and many more.

What Are They Used for?

Because they serve such a simple service, these machines can be utilized for a number of important functions. The type of purpose they serve depends on their classification and obviously their functionality. Certain models and types have features that may serve one job better than another.

Surface supplied divers utilize compressors to receive their clean air. School buildings also often power their HVAC pneumatic control system valves with the use of a compressor. Compressors also often power pneumatic tools like jackhammers or nail guns, or they can fill high-pressure tanks or tires.

Where Can I Purchase One?
