LeROI Compressor: Parts, Service & Support from Kingsly Compression

a blue machine in a room

LeROI compressors have earned a legendary reputation in the natural gas and industrial sectors. Known for their reliability and rugged engineering, LeROI rotary screw compressors continue to power operations across oilfields, plants, and gas processing sites.

But as technology evolves and original units age, it becomes harder to find support, parts, and expert guidance—especially for legacy systems.

That’s where  Kingsly Compression comes in. With over 30 years in the natural gas compression industry, we specialize in providing parts, service, and rebuild options for LeROI compressor systems—helping operators minimize downtime while maximizing the life of their equipment.

The Legacy of LeROI Compressors

Founded over a century ago and now part of the Gardner Denver family, LeROI Compressors are widely recognized for their rotary screw compressor designs—particularly for natural gas and process gas applications. Their products include:

  • Single-stage rotary screw gas ends
  • Two-stage rotary screw systems
  • Integral gear designs for higher efficiency
  • Packaged compressor skids for field-ready installation

LeROI’s focus on long bearing life, optimized porting, and variable Vi has made their compressors a staple in midstream and upstream operations.

Still Running a LeROI Compressor?

If your site still operates a LeROI rotary screw compressor, you’re not alone. Thousands of systems are still in operation across the country due to their solid build quality and performance history.

However, with age comes the usual challenges:

  • Difficult-to-source parts
  • Reduced OEM support for older models
  • Increased service demands and potential for downtime

Whether you’re managing one unit or a fleet of older LeROI compressors, maintaining system integrity comes down to sourcing the right parts and technical expertise.

Should You Repair or Replace Your LeROI Compressor?

As compressors age, operators eventually reach a crossroads: repair, rebuild, or replace? At Kingsly Compression, we help you make the right call based on:

  • Current performance metrics
  • Replacement part availability
  • Downtime risk vs. long-term ROI
  • Upgrade opportunities to improve efficiency

For many clients, rebuilding their LeROI unit with upgraded internals or modern control panels can extend usage by another 5–10 years. Others choose to replace with a newer compressor package that offers higher throughput, lower emissions, or a smaller footprint.

We offer both options—and we’ll help you weigh the cost-benefit of each.

Upgrade to a Modern Compressor Package

If it’s time to retire your aging LeROI unit, we provide custom compressor packages designed for today’s industry standards. Built for field-ready deployment, Kingsly packages offer:

  • Rotary screw or reciprocating compressors
  • Electric or gas drive configurations
  • Prewired and skid-mounted systems
  • Full PLC control and monitoring panels

Each system is engineered in-house and backed by Kingsly’s commitment to quality and performance. Check out our custom compressor packages for replacement options tailored to your site.
