Quincy QR-25 vs Ingersoll Rand 2475

Q: What’s the main difference between the QR-25 and 2475?

The QR-25 is pressure-lubricated and rebuildable; the 2475 is splash-lubricated and more affordable.

Q: Can both compressors run continuously?

Yes, both are rated for 100% duty cycle.

Q: Which compressor is quieter?

The QR-25 runs at slower RPMs and is generally quieter than the 2475.

Q: What’s the max pressure of each unit?

R-25: up to 500 psig. 2475: up to 175 psig.

Q: Is the QR-25 worth the higher price?

For heavy-duty use and long-term ownership, yes. It offers rebuildability and extended lifespan.

Q: Can I use the 2475 for CNC machining?

Only if your PSI requirements are below 175. Otherwise, the QR-25 is better suited.

Q: Which compressor is easier to install?

The 2475 is lighter and more compact, making installation simpler.

Q: Do both models require oil changes?

Yes. QR-25 every 1,000–2,000 hours; 2475 more frequently due to splash lubrication.

Q: Are parts easy to find for both?

Ingersoll Rand has wider global distribution; Quincy parts may be harder to source internationally.

Q: Which model has a better warranty?

QR-25 offers a 5-Year True Blue Warranty with authorized startup; 2475 offers 2 years standard.

Introduction

When it comes to heavy-duty reciprocating air compressors, two models consistently stand out: the Quincy QR-25 and the Ingersoll Rand 2475. Both are built for industrial-grade performance, but they serve slightly different needs. The QR-25 is known for its pressure-lubricated design and rebuildable cast-iron components, while the 2475 offers a more affordable, splash-lubricated alternative with solid reliability.

This comparison breaks down their specs, strengths, and weaknesses to help you choose the right compressor for your shop, facility, or production line.
