10 Things to Consider When Buying reciprocating gas compressors

When industrial processes demand high-pressure gas delivery, reciprocating gas compressors—also called piston compressors—often earn their stripes. Unlike screw-based units, they excel at high compression ratios, efficient off-design operation, and gas type versatility. But choosing the right model requires balancing technology, sizing, materials, and maintenance needs.

1. Reciprocating vs Screw: Know Your Technology

• Pressure Capability: Reciprocating compressors deliver much higher pressures (often exceeding 1,200 PSI or ~80 bar), while screw compressors are generally limited to ~250–600 PSIG

• Duty Cycle & Noise: Screw compressors offer continuous operation and smoother, quieter performance. Reciprocating units deliver cyclic duty and generate more vibration—though they perform better under partial‑load conditions .

• Application Fit: Reciprocating units thrive in high-pressure, intermittent-duty or skid-mounted gbp compressor setups—ideal as industrial piston compressors in oil & gas, process plant, or nitrogen boosting lines.
