Piston vs. Screw Compressors: Which is Right for Your Business?
Piston compressors (also known as reciprocating compressors) and rotary screw compressors are two of the most commonly used technologies in the compressed air industry. Choosing between them depends on your specific application, usage patterns, and future needs.
Use this guide to help make the right decision.
Key Questions to Ask Before Choosing
Before selecting a compressor, consider:
-
What application is the compressor needed for?
-
How much airflow does your facility require?
-
What pressure level do you need?
-
Do you require clean, dry air? (If so, a dryer and filtration system may be necessary.)
-
How many hours per year will the compressor run?
-
How many shifts do you operate each day?
-
Is your airflow demand constant or does it fluctuate? (A VSD compressor could save energy if demand varies.)
-
Are there plans to expand your facility, requiring more air capacity?
Comparing Piston and Screw Compressors
| Factor | Piston Compressors | Screw Compressors |
|---|---|---|
| Initial Cost | Lower | Higher |
| Operating Costs | Higher over time | Lower over time |
| Energy Efficiency | Less efficient | More efficient |
| Duty Cycle | Short-duty cycles; not for continuous use | Continuous-duty; ideal for constant demand |
| Service Intervals | More frequent maintenance | Longer service intervals |
| Noise Levels | Noisy | Quieter operation |
When to Choose a Piston Compressor
-
Air demand is small.
-
Compressed air is used intermittently.
-
Keeping initial costs low is a priority.
When to Choose a Screw Compressor
-
Air demand is continuous or frequent.
-
Noise reduction is important.
-
Longer service intervals are preferred.
-
Overall operating costs need to be minimized.
Conclusion
Choosing between a piston and screw compressor depends on your current needs, your operating environment, and your future plans. Both technologies have clear advantages depending on how and where they’re used.
