With configurable pressure options from 100 to 175 PSI, this compressor adapts to your system without compromise.
⚙️ Performance by Pressure (Dial In Your System)
Choose the pressure that fits your operation—without oversizing or sacrificing efficiency:
- 100 PSI → 71 CFM
- 125 PSI → 62 CFM
- 150 PSI → 55 CFM
- 175 PSI → 49 CFM
👉 Airflow is optimized at each pressure level, giving you the right balance of CFM and PSI for your specific application.

⚠️ What Happens When You Undersize a Compressor?
It’s one of the most common (and expensive) mistakes:
- Constant pressure drops
- Equipment starving for air
- Increased wear and overheating
- Higher energy costs from overworking the unit
👉 The result? Downtime, lost productivity, and premature failure.
That’s why choosing the right PSI + CFM combination matters—and why we help you get it right the first time.
