Discover used, secondhand and surplus compressors from IPP – oil-free, rotary and reciprocating models ready to ship

IPP’s ready-to-ship compressors deliver performance and help you save time and money on plant utilities

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

FAQ

Compressor FAQ

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

What industries rely most on industrial compressors?
Chemical, oil and gas, food and beverage, pharmaceutical, and general manufacturing industries all rely on compressors for essential process and utility functions.
How do rotary screw compressors compare to reciprocating compressors?
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.
What maintenance is required for industrial compressors?
Regular maintenance includes checking oil levels, inspecting seals and bearings, monitoring pressure settings, and replacing filters to ensure efficient and safe operation.
What are the benefits of buying used or secondhand process equipment from IPP?
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.
