When your operation depends on reliable gas compression for process, storage, or transfer, industrial compressors deliver the performance needed to keep operations moving. With over 47 years of process equipment expertise, IPP provides immediate access to high-quality used compressors sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. Choosing used compressors from IPP helps companies reduce capital costs, shorten procurement timelines, and maintain consistent system reliability.

Industrial compressors are designed to increase the pressure of gases for transportation, storage, or process operations. They are essential for applications across chemical manufacturing, energy production, food and beverage processing, and general industrial services.

Primary uses across industries

In chemical processing, compressors move feed gases through reactors and separation units.
In oil and gas, they transport natural gas, vapor recovery, and process gas management.
In food and beverage production, compressors provide air for packaging lines, fermentation, and pneumatic systems.
In pharmaceutical manufacturing, they supply clean compressed air for production and packaging.
In industrial utilities, compressors operate pneumatic tools, controls, and facility services.

Types of materials processed

Air for pneumatic systems and utilities
Process gases such as nitrogen, oxygen, hydrogen, and carbon dioxide
Hydrocarbon gases like methane, ethylene, and propane
Refrigerants for process cooling systems

Common materials of construction

Compressors are designed for durability, chemical compatibility, and safe operation under pressure:

Stainless steel for corrosive gas handling and sanitary applications
Carbon steel for general compressed air and inert gas services
Specialty alloys for high-pressure, high-temperature, or reactive gas environments

Key features of industrial compressors

Reciprocating, rotary screw, centrifugal, and diaphragm designs available
Oil-lubricated and oil-free models for different process needs
High-pressure and variable speed options for flexible operations
Skid-mounted systems for easy integration into existing facilities
Built-in safety and control systems to ensure operational reliability

Compressor FAQ

Have questions about Compressors or our services? Learn more about our products and why customers choose IPP.

Chemical, oil and gas, food and beverage, pharmaceutical, and general manufacturing industries all rely on compressors for essential process and utility functions.

Rotary screw compressors are ideal for continuous duty and large volume needs, while reciprocating compressors are better suited for smaller volumes and higher-pressure applications.

Regular maintenance includes checking oil levels, inspecting seals and bearings, monitoring pressure settings, and replacing filters to ensure efficient and safe operation.

Buying used from IPP can save up to 70% compared to new equipment, allow for faster project implementation, support sustainability, and leverage over 47 years of industry expertise.
