OEM vs. Aftermarket: What’s the Better Move for Your Rotary Screw Compressor?
Many facilities default to OEM parts when servicing their rotary screw compressors, thinking it's the "safe" or “only” option. But in today’s world of high-quality aftermarket solutions, sticking with OEM could mean paying more and waiting longer without gaining any real benefit.
In this article, we’ll walk through the advantages of aftermarket compressor parts and why thousands of facilities are making the switch.
1. Cost Savings Without Compromise
OEM parts often come with a steep markup. You’re paying for the name on the box, not necessarily better performance.
Premium aftermarket parts are engineered to meet or exceed OEM specifications, meaning you get the same (or better) reliability at a fraction of the price.
2. Reduced Lead Times
Downtime is expensive. OEM parts are often backordered or shipped from overseas, creating frustrating delays.
Aftermarket suppliers like ACS stock a wide range of parts and ship fast - because getting you back up and running yesterday is the goal.
3. Personalized, Problem-Solving Support
OEM service reps are often tied to the brand’s internal processes.
Aftermarket teams are more flexible, responsive, and focused on solving your issue, not selling a part quota. You’re more likely to talk to a real expert who knows your compressor inside and out.
4. No Drop in Quality
Worried about quality? You shouldn’t be.
Top-tier aftermarket parts (filters, oil, separators, gaskets) are often manufactured by the very same companies that supply the OEMs. The difference? You’re not paying for the label.
Break the Brand-Name Habit
At the end of the day, it’s not about the logo on the box. It’s about keeping your system running efficiently, affordably, and with minimal downtime.
If you're still relying on OEM out of habit, it might be time to take a second look. The aftermarket advantage is real. And it’s helping facilities just like yours save money and time every day.
