Types of Used Compressors Available
Aaron Equipment offers several types of used compressors designed for different pressure, flow, and process requirements:
Air Reciprocating Compressors – Positive displacement compressors that use pistons to compress air, ideal for intermittent duty and high-pressure applications.
Air Rotary Compressors – Continuous-duty compressors that deliver steady airflow using rotary screw or vane mechanisms for industrial operations.
Air Dryer Compressors – Integrated systems that remove moisture from compressed air to prevent corrosion and maintain product quality.
Reciprocating Gas High Pressure Compressors – Heavy-duty compressors designed to handle gases at high pressures in energy, chemical, and industrial applications.
Compressor Applications & Industry Uses
Used compressors are essential across industries where pressurized air or gas is required for production, processing, or utility systems. Common applications include:
Pneumatic conveying and material handling
Process air supply for manufacturing and packaging
Refrigeration and cooling systems
Chemical and petrochemical gas compression
Instrument air systems in plants and refineries
Energy and gas processing operations
Compressors play a critical role in maintaining consistent pressure, flow, and system reliability across these operations.
Used Compressor Buying Considerations
When selecting a used compressor, evaluate both operational requirements and equipment condition:
Pressure & Flow Requirements: Match compressor output (PSI and CFM) to your application.
Compressor Type: Determine whether reciprocating or rotary designs best fit your duty cycle.
Gas Type: Ensure compatibility if compressing gases other than air.
Cooling Method: Consider air-cooled vs. water-cooled systems based on facility infrastructure.
Condition & Maintenance History: Review service records, wear components, and overall unit condition.
Why Buy Used Compressors
Purchasing used compressors can significantly reduce capital costs while providing reliable performance for industrial applications. Many used units are available for immediate shipment, helping facilities avoid long lead times. Buying used also allows access to proven compressor models that have demonstrated durability in real-world operating environments.
Sell Your Used Compressors
Aaron Equipment purchases surplus and used compressors, including air compressors, gas compressors, and integrated systems. Whether you are upgrading equipment or liquidating assets, our team can assist with equipment evaluation, buyouts, or consignment options.
A compressor is a mechanical device that increases the pressure of air or gas by reducing its volume. Compressors are widely used in industrial applications to power pneumatic systems, support processing operations, and handle gases in manufacturing and energy environments.
Common types of used compressors include reciprocating compressors, rotary screw compressors, air dryer systems, and high-pressure gas compressors. Each type is designed for specific pressure ranges, duty cycles, and applications, from intermittent use to continuous industrial operation.
Choosing the right compressor depends on required pressure (PSI), airflow (CFM), duty cycle, and the type of gas being compressed. It is also important to consider cooling methods, system integration, and overall equipment condition to ensure reliable performance.
The cost of a used compressor varies based on type, capacity, manufacturer, and condition. Larger or high-pressure units typically cost more than smaller systems. Contacting a sales representative can help determine current availability and pricing based on your requirements.
Yes. Aaron Equipment purchases surplus and used compressors across a wide range of types and configurations. If you have equipment available for sale, you can submit your details for evaluation and potential buyout or consignment.
