In this episode of Beyond Compression, we explore why a well-developed centrifugal compressor specification is critical to equipment reliability, energy efficiency, project costs, and long-term operational performance. The decisions made during the specification process influence nearly every aspect of a compressor package, from aerodynamic design and driver selection to controls, auxiliary systems, installation requirements, and lead times.

We discuss the process and site data needed to properly select a centrifugal compressor, including flow requirements, inlet conditions, gas properties, discharge pressure, ambient conditions, electrical requirements, and hazardous-area classifications. We also examine how industry standards such as API 617, API 672, API 614, and JIP 33 apply to different compressor applications—and how specifying unnecessary or conflicting requirements can increase costs and delay a project without improving reliability.

In this episode, you’ll learn:

• Why the compressor specification serves as the engineering foundation for the entire project
• What process, site, and operating data are required for proper compressor selection
• How to determine which industry standards apply to a particular application
• Why driver, electrical, controls, and hazardous-area requirements should be established early
• How incomplete information and late-stage changes can affect equipment design, costs, and project schedules
• Why early collaboration among the owner, EPC contractor, and compressor manufacturer can reduce risk and improve long-term performance

A centrifugal compressor specification is much more than a procurement document. When operating conditions and project requirements are clearly defined from the outset, project teams can avoid unnecessary scope creep, reduce engineering rework, improve equipment efficiency, and select a compressor package that meets the facility’s actual needs.

OEM and Non-OEM parts may look the same—but do they really perform the same?

In this episode of Beyond Compression, host Pam Wasielewski sits down with Dave Sleeman, a seasoned service expert, to break down one of the most common—and costly—assumptions in industrial maintenance: that OEM and non-OEM parts are interchangeable.

From reverse engineering and material selection to micron ratings, tolerances, and long-term performance, this conversation pulls back the curtain on what manufacturers see that others don’t. Dave shares real-world field experience, including a case where a seemingly harmless non-OEM air filter led to reduced efficiency, vibration alarms, impeller damage, and nearly $50,000 in unplanned costs.

In this episode, you’ll learn:

• Why “looks the same” doesn’t mean “performs the same.”
• What’s lost when parts are reverse-engineered without original design data
• How non-OEM components contribute to early-life failures
• The hidden costs of downtime, efficiency loss, and secondary damage
• What OEM parts protect beyond performance—warranty, safety, and compliance

If you’ve ever considered saving a few dollars on replacement parts, this episode explains why the real cost often shows up later.
