Used Compressors for Sale

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. 

Our compressor models also cover various types of gases. Our inventory includes:

• Used natural gas compressors
• Used syngas compressors
• Used CO₂ compressors
• Used hydrogen compressors

We also sell used compressor parts, including used stainless steel compressor tanks.

Other Used Air Compressor Types

While axial and centrifugal air compressors may be the most common, we also sell many other types of compressors, including the following:

• Belt-driven compressors: As their name indicates, these industrial compressors have a belt attached to the motor and the air pump. Many facilities prefer to use these products because they can adjust their pressure quickly.
• Diaphragm compressors: Diaphragm compressors are a type of reciprocating compressor. The diaphragm protects the pump, making these products ideal for aquatic uses.
• Reciprocating balanced opposed compressors: These positive displacement compressors arrange multiple cylinders so that one piston’s motion counters the other’s. Various industries use this equipment to compress gases, such as natural gas.
• Refrigeration compressors: These compressors are specifically designed to compress the refrigerant in a refrigerated system.
• Rotary screw compressors: As mentioned above, rotary screw compressors use rotating screws rather than pistons and are suitable for continuous use.
• Train compressors: Train compressors are designed for railway and locomotive applications, such as train horns and air braking systems.

When choosing an industrial compressor, consider your facility’s needs and select an option that serves as the most effective solution.
