Airend Rebuilds, Upgrades & Replacements
Restore compressor performance, adapt to changing air demand, and prepare for future maintenance with OEM airend services backed by FS-Elliott engineering expertise.
OEM Expertise
Protect the Heart of Your Compressor
The airend is where compression happens, and where precision directly influences compressor performance. As components wear or production requirements change, the right service strategy can help restore efficiency, extend equipment life, and protect your investment.
FS-Elliott provides overhauls, remanufactured airends, rerates and derates, and new replacements. Our service team and authorized channel partners help evaluate your options, while our dedicated Rapid Response Service Center supports repair turnaround.
Airend Services Built Around Your Operating Needs
Choose a path forward based on equipment condition, required performance, and maintenance priorities. FS-Elliott offers solutions to restore your existing airend, adapt its output, or plan a replacement.
Restore Performance from the Inside Out
Extend the working life of your existing airend through a complete teardown, inspection, and overhaul. FS-Elliott provides an inspection report to establish component condition and the recommended repair scope.
The process includes cleaning, inspecting, and balancing internal components, with key parts replaced with genuine OEM components as needed. The goal is to restore the airend to OEM specifications and prepare it for continued dependable service.
Renew Performance, Retain Value
A factory-remanufactured airend offers an alternative when your existing unit reaches the end of its service life. FS-Elliott combines suitable refurbished components with replacement parts to deliver like-new performance.
Internal components are inspected, cleaned, and balanced, and the completed airend undergoes performance testing. Reusing serviceable materials reduces waste while providing another option for managing equipment renewal and cost.
Match Your Compressor to Today’s Demand
Adjust airend performance as your facility’s requirements evolve. A rerate can increase flow or pressure to support growing production needs, while a derate reduces excess capacity when demand decreases.
FS-Elliott evaluates aerodynamic modifications against your compressor design and target operating conditions. When feasible, these changes can improve efficiency, reduce energy waste, and help you adapt existing equipment instead of replacing the entire compressor.
A New Airend for the Next Stage of Operation
When an overhaul or modification is no longer practical, a new OEM airend provides a complete replacement built to original equipment specifications. FS-Elliott helps evaluate compatibility with your compressor and operating requirements.
A replacement can be installed for continued operation or maintained as a dedicated spare. Combined with a planned service strategy, it gives your team greater flexibility when preparing for maintenance or an unexpected repair.
Dedicated Service, Faster Turnaround
Restore airend performance with support from a facility dedicated to overhauls, rerates, and remanufacturing. FS-Elliott’s Rapid Response Service Center combines teardown, inspection, and assembly capabilities with supporting inventory to streamline repairs and shorten turnaround times.
Our team evaluates component condition and reuses suitable materials where appropriate, helping extend equipment life and reduce waste while maintaining OEM standards.
Keep Your Replacement Airend Ready
Prepare for future maintenance or an unexpected repair by storing a new or refurbished airend in FS-Elliott’s secure, climate-controlled facility. Ongoing maintenance and mechanical testing before shipment help keep your replacement ready for service.
Stored airends can often ship within 24 hours, reducing the wait for replacement equipment. Our team can confirm program terms, availability, and shipment timing for your airend.
Frequently Asked Questions
What is the difference between an overhaul and a remanufactured airend?
An overhaul restores your existing airend through teardown, inspection, cleaning, balancing, and component replacement as required. A remanufactured airend is a factory-built unit that combines suitable refurbished components with replacement parts and undergoes performance testing.
Can my compressor be modified for different flow or pressure requirements?
A rerate or derate may be possible, depending on your compressor design and target conditions. FS-Elliott evaluates the available modifications to determine whether your existing equipment can meet updated requirements.
Can I keep a replacement airend ready for future use?
Yes. New and refurbished airends can be maintained through the Rapid Response Storage Center. The program includes climate-controlled storage, ongoing maintenance, and mechanical testing before shipment. Contact FS-Elliott to discuss program terms and availability.
How do I determine which airend service is right for my equipment?
Share your compressor model and serial number, operating concerns, current and required flow and pressure, and maintenance schedule. FS-Elliott and your authorized channel partner can help compare the options. A detailed overhaul scope is established following teardown and inspection.

Rerate or Replace? How to Maximize Compressor Efficiency Without New Equipment
Rerating an existing compressor package provides a cost-efficient path to enhance plant air capacity without purchasing a new centrifugal compressor package. This approach eliminates the complexities associated with minimum bid procurement, budget approval, and permits for acquiring a new compressor. Organizations can increase capacity and efficiency by rerating existing equipment while saving time and money.
