Industrial Air Compressor
Find an electric air compressor or gas air compressor to suit your needs
An industrial air compressor is used to create pressurized air with specific pounds per square inch (p.s.i.) ratings. This compressed air can then be released, using a series of short bursts, for a wide range of applications.
Compressors can be defined by the type of energy they use to pressurize air. Electric air compressors and gas air compressors use electrical power and gasoline or diesel, respectively, and each of these two options has its advantages and limitations. There are also several internal processes used to compress air, which you should familiarize yourself with to help you select the ideal product.
Three Types of High Pressure Air Compressors
In terms of the internal process used to pressurize air, you have three main options: reciprocating compressors, rotary screw air compressors and rotary centrifugal air compressors.
Reciprocating industrial air compressors use positive displacement to pressurize air. In other words, the pressure of the air is increased by reducing its actual volume. Single-stage reciprocating air compressors produce air ranging from 70 to 100 p.s.i., while double-stage reciprocating compressors are used to generate air in the range of 100 to 250 p.s.i.
All rotary air compressors are positive displacement machines as well. Rotary screw air compressors use single-stage spiral or helixes to cool and pressurize air right inside the machine itself, while rotary centrifugal air compressors use impellers. An impeller is an air compressor part that uses kinetic energy created by its own movement to convert air from low to high pressure.
Electric versus Gas Air Compressors
Electric air compressors are easy and inexpensive to operate. However, they do have inherent limitations, and you will require a continuous power source to run them. Their range is only as long as the extension cord you use, unless you want to introduce electrical generators to the equation.
For remote use, a gas air compressor is an easier solution. These gasoline- or diesel-powered air compressors are slightly more expensive to use and maintain, but if you have an ongoing need to use an air compressor in a remote location or out in the field, they are probably your best bet, as lugging around a generator is cumbersome and needlessly difficult.
