Airends & Rebuilds

Every compressor eventually requires rebuilding to regain full performance. Ingersoll Rand service engineers can meet your needs using innovative rebuild or exchange programs.


Centrifugal Rotor Clean & Balance

Benefits Include

  • Prevents premature failure of the pinion and bearings
  • Keeps your compressor at peak performance
  • Allows you to continue use of your original rotor assemblies for an indefinite amount of time


The rotating assembly is one of the most critical components of your Centac air compressor. If it out of balance, your compressor will not perform to it's full potential. With normal operation of a compressor, your rotating assembly will attract a buildup of solids on the induction side of the impeller. This buildup can result in an increase in vibration on the individual stages of the compressor. The amount of acceptable vibration varies among models of compressors, however, the pinion vibration increases the probability of nuisance trips or premature failure of the pinion and bearings increases. Failures of this type can be very costly if replacement of the part is required.

To keep your compressor performing at it's full potential, Ingersoll Rand offers clean and balancing services. By taking advantage of this OEM repair service during routine maintenance, Centac owners can continue to use their original rotor assemblies for an indefinite period of time.
Airend Exchange Program

Reliability, performance and availability are the main reasons customers prefer the Ingersoll Rand Rotary Compressor Airend Exchange Program. This program supports oil-flooded & oil-free rotary screw compressors.

Planned airend exchanges are less costly and eliminate unscheduled interuptions to your operations and provides the most economical maintenance program for rotary compressors.

The Airend Exchange Program is a three-tier solution structure. When a rotary compressor airend needs to be replaced, there are three potential solutions:

  1. New Airend - 24-hour lead time for production items, credit for core return
  2. Remanufactured Airend - short lead time, credit for core return
  3. Airend Rebuild Kit* - rebuild in field, extends downtime
    * Not an option for CD airends.

Airend Exchanges may qualify for PackageCare.

The standard warranty is:

New Airend - one (1) year with Ultra Coolant
Remanufactured Airend - one (1) year
Airend Rebuild Kits - six (6) months

Warranties and PackageCare Service Contracts are subject to the use of Ingersoll Rand Ultra Coolant and installation performed by Ingersoll Rand Authorized Service Providers.

Airend Rebuild Kits contain all the parts needed to rebuild your rotary compressor airend to its original specifications, guaranteeing optimum performance and reliability. To further protect your investment, only Ingersoll Rand Certified Engineers are approved to provide this rebuild service.
