Used and Surplus Air Compressors

Air compressors are devices that convert power into potential energy, which in turn is used to power various types of equipment. These devices use an engine or a motor to pump air into a tank, which is also referred to as a holding tank. This air is then used to power devices. Also, it can be stored or released into an environment with less or equal PSI capacity than the capacity of the tank. At J&M Industrial, we possess an inventory of quality surplus and used air compressors from brands such as Quincy, Redmax, Gardener Denver, and so on. These air compressors can meet the requirements of many manufacturing applications.


Types of Air Compressors


Types of Air Compressors

Whether new or used air compressors, they are classified into different types based on the following categorization:

  • Level of Pressure Delivered: Air compressors are distinguished into three types based on the amount of pressure delivered. These include the following:
    • High pressure air compressors (HPACs): These air compressors possess a discharge pressure of 1,000 psi or above.
    • Medium pressure air compressors (MPACs): They offer a discharge pressure of 151 PSI to 1,000 PSI.
    • Low pressure air compressors (LPACs): The air compressors of this type are ideal for pressure applications requiring air pressure of 150 PSI or less.
  • Method of Air Compression: There are several methods of air compression. Most air compressors following these types of compression:
    • Positive Displacement: These compressors force air in a low volume chamber. As the maximum pressure is achieved, a valve or port is opened and the air is discharged to the outlet. This discharge is made through the compression chamber. Positive displacement compressors are further distinguished into the following types:
      • Piston Type Compressors: These compressors feature pistons increasing the pressure as well as reducing the air volume. Piston type compressors are also known as reciprocating compressors. They may follow two types of compression cycles: single-stage and two-stage. A single-stage piston is known so because it compresses the air in one stroke. A two-stage piston compresses the air in two phases. The first piston compresses air and moves it into a small cylinder, where it is compressed by another piston. This generates high pressures.
      • Vane Compressors: These compressors use a slotted rotor with a blade displacement, which in turn guides air into the chamber. The air is compressed in the chamber. Vane compressors deliver a fixed volume of air at elevated temperatures.
      • Rotary Screw Type Compressors: They utilize two helical screws that drive air into the chamber, where compression occurs at the turn of the screw.
    • Dynamic Displacement: These compressors feature a rotating component which imparts kinetic energy to the air. This air is converted into pressure energy. The following are a few important types of dynamic displacement compressors.
      • Axial Compressors: These compressors make use of rotating blades to compress the gas. The gas flows parallel to the rotation axis. These compressors achieve the highest volumes of air ranging from 8000 to 13 million CFM.
      • Centrifugal Compressors: These compressors utilize rotating impellers for producing high-pressure discharge. They rotate at high speeds in comparison to other types.
