Airend Warranty

Air Engineering stands behind our work.


Air Engineering® is proud to offer our 5 year extended warranty program for airends we rebuild, at no additional cost.

To participate in the extended warranty program the customer will need to perform the following:

• Use Air Engineering® brand High Performance synthetic lubricant, air intake filters, oil filters and air/oil separators during the warranty period. These products must be used according to the compressor manufacturer's recommendations.

• Perform and document all manufacturers recommended maintenance on the compressor.

If you select Air Engineering's® exclusive Two-Year Warranty Program, please inform your sales representative.



If a customer does not wish to participate in Air Engineering's® Extended Warranty program, they can still enjoy the benefits of our standard One Year, 8000 hour warranty. Air Engineering® warrants s it rebuilds for one full year or 8000 hours, whichever occurs first.

  • For this warranty to remain in effect, the customer will need to perform the following:
  • Replace the bearings in the compressor drive motor prior to re-installation of rebuilt airend.
  • Obtain a sample of the OLD oil compressor lubricant. Send sample in to Air Engineering® for laboratory analysis. The sample kit will be provided FREE of charge and the analysis is performed FREE of charge.
  • Drain OLD compressor lubricant - Refill compressor with new lubricant that is designed for use in rotary screw compressors. (Air Engineering® lubricant is the best over all value - feel free to call Air Engineering® if you have any lubricant questions)
  • Replace Air / Oil Separator, Oil Filter, and Strainers with new elements.
  • Perform all other manufacturer's recommended maintenance items.
  • Document the actions taken as described above.

In the event that laboratory analysis of the OLD compressor lubricant reveals dangerous or unusual conditions, Air Engineering® will make you aware of those conditions. Based on the findings of that oil analysis, Air Engineering® may prescribe actions that will correct those conditions. The customer will agree to execute such prescribed remedies.

In the event of a problem or failure:

  • Written notice of such failure will be provided to Air Engineering within thirty (30) days of discovery of such failure. Notice should be sent to:
