Used Compressors for Sale

Compressors increase the pressure of gases to create energy for powering various tools and machinery. Some industries that rely on compressors include automotive, pharmaceuticals, chemical processing and woodworking. In these industries, these machines are used to: 

• Create air curtains
• Power control valves
• Convey materials
• Dry products after processing

Used Air Compressors Available at LCEC

At LCEC, we carry a wide range of compressor types, including: 

• Positive displacement pumps: This broad compressor category stores air and compresses it to increase pressure and potential energy. Within this category, you can also find rotary screw and reciprocating styles. Rotary screw compressors handle continuous use with two internal rotors that spin in opposite directions. Reciprocating models use a piston inside a cylinder to compress air.
• Dynamic compressors: This broad category generates horsepower with rotating blades. These blades restrict air to create pressure, and the machine stores kinetic energy as static. Axial compressors are a type of dynamic compressor that work for high-power applications. Centrifugal compressors also fall in this category, and they slow and cool air to create energy.

Used Centrifugal Compressors and Axial Compressors 

Axial and centrifugal compressors are two types of dynamic compressors, which generate horsepower with rotating blades. The blades create pressure by restricting airflow. The machine then stores kinetic energy as static energy. 

While axial and centrifugal compressors belong in the same category, there are notable differences between them. Axial compressors are best suited for high-power applications. The air passes through the compressor shaft through rows of blades. The air’s velocity gradually increases as the stationary blades turn kinetic energy into pressure. Often, axial compressors have built-in balancing drums that counterbalance any thrust.

Centrifugal air compressors are often larger than axial compressors and operate at faster speeds. 

A hallmark of a centrifugal compressor is radial discharge flow, meaning it draws air up into the impeller, then pushes it toward the perimeter. The air movement occurs at the same time as an increase in pressure, which produces kinetic energy. The air then passes through the impeller, where it turns into pressure.

The impeller on a centrifugal compressor can be stainless steel or aluminum.
