Air Compressor: What You Need to Know, How it Works, and How to Choose One

Facts about an Air Compressor

An air compressor is a device that changes power from gasoline, diesel or electric power resource into energy that is stored in pressurized air form. The device pushes air forcefully into a storage compartment in which the pressure is significantly heightened. These tools are highly regarded in modern industry because they are believed to be, by far, more efficient, fast and powerful.

How It Works

After consistently and forcefully pushing air into the tank, the tank reaches the limit and triggers the compressor to shuts off. This air is stored and is ready to use when the need arises. The usage involves making use of the energy (kinetic) as it leaves the tank. Similarly, when the pressure hits the lowest point, the air compressor automatically turns back on. The technology is practically used to perform tasks in several scenarios at the workplace. One common usage of this technology also referred to as pneumatic pressure system is in vacuum cleaning machines and ground compression machines. Large motor trailers also use this technology to supplement the primary breaking system. Technically, there are several ways to achieve air compression. Two methods are notable in this respect: positive displacement and negative displacement.

How to Choose Your Ideal Air Compressor


One basic tool to bring to use in choosing a compressor is to consider the job you need to do. Therefore, the air compressor you choose should be able to effectively handle the intended task. For purposes of simplifying the selection guide, we can view compressors as belonging to two distinct categories, i.e. portable compressors and stationary ones. Your home or office will most likely be well served well with a portable compressor. On the other hand, stationary compressors are by far more powerful and are suited for large-scale production and automotive usage. It is also evident that the stationary compressors which are usually much larger are likely to cost you much more than portable compressors.

Factors to Consider When Selecting an Air Compressor

• The type of pump. You need to consider the nature of the task to which you want to apply the air compressor. The dynamics may range from continuously operated copeland compressors, single stage, 2 stage, and oil free, oil lubricated ones, and start and stop types.

• Portability. It has been mentioned that portable compressors are ideal for specified places and tasks. Portable compressors also come in a range of weight and size. The lightweight portable compressors can easily be lifted and transported to various locations on a site. The heavier ones are normally fitted with wheels to ease their movement.

• Power source. You must ask what type of power source you want your compressor to tap into. There are various power options for which compressors are designed to utilize. The most common ones are either gas/diesel or electric powered.

• The performance rating: Some machines may be tuned to deliver far larger power output than you really need.

• The size of the tank. Compressors may come with a large air tank, relatively small tanks and even no tank. Usually, the size of the tank determines how long the compressor can run in a task session. Air compressor tank sizes are available from a modest one gallon to over eighty gallons.
