Air compressor has been used for over 100 years and brings human a lot of benefits as the air tool. The outstanding features of this tool are safe, flexible, clean and convenient. These machines had to get the love from the customers and evolved into the highly reliable piece. That explains why they become indispensable in most of the applications now.

Like any products in the market, there are different kinds, brands, and features that make you get confused when choosing an air compressor. To solve that problem, besides reading http://airtoolresource.com/best-air-compressor-reviews, you can also consider some option below.

First, what should we get if getting an air compressor? As with any tools, air compressor help, we save time, money for every given project. When using air compressors, you can easily realize that they are lighter and more powerful than any electric and battery devices.

Although in the market, there are a lot of types of compressor, they are performing the same function. That is to increase the pressure and reduce the volume of a gas such as air. They work by filling a chamber with air and reducing the chamber’s volume. We call them positive displacement compressors. We can easily find them in the market with reciprocating, rotary screw and rotary vane compressors.

Reciprocating or Piston compressors are the most popular products in ranges from fractional to very high horsepower. Besides, rotary compressors (Screw and Vane) and the centrifugal compressors are also found in an industrial/commercial environment. The article will mention some option of piston compressor that helps you to have the best view about these products.

1. Single stage or two stage
For piston compressor, they come with two types. The single-stage compressors have just one piston and top out at around 150 psi. It works by drawing air and compressing the air to its final pressure in single piston stroke. Besides, a single stage pump has a higher CFM rating than a two stage pump.

Two-stage piston compressors have two pistons to deliver the air pressure and top out at about 200 psi. Besides, single-stage compressors are used for more heavy-duty applications at home. The two-stage compressor is used for industrial setting.

2. Cubic Feet per Minute or CFM
HP is not the only one factor that you can consider when buying an air compressor. CFM is also a measure of volumetric flow. It is a mathematical formula of the bore, stroke, and rpm(Bore x stroke x rpm/2200=DCFM). Depending on the psi of the compressor, CFM can change. It means with different psi; two tools will not necessarily have CFMs that add together.

3. Electric motors or horsepower
Compressors are valued by HP ( horsepower). Some manufacture rate their products by peak horsepower or brake horsepower. Peak HP is the maximum output of a motor producing while it has the star winding engaged. Peak HP can be five times the rated HP. However, in the normal condition, the tool does not work with peak HP, therefore, if you compare air compressor by this figure, that will bring us a side view.

Most of the manufactures rate their motors by Hp which develop after the motor come up. This number usually referred to rated Hp and true indication which motors can suffer for an extended period.

Some other factors that we should consider when buying an air compressor are Duty Cycle and Service factor. Duty cycle is rated as continuous or intermittent, that is the time under full load. Service Factor is the percentage of rated HP which at that point, the motor can be safely operated. Some higher service factors help motors to handle with different conditions without overheat or premature motor failure.

In conclusion, these are some basic factors that you must to see when buying a piston air compressor. Hope after reading this article, you have knowledge about air compressor and make the last decision.
