Choosing the right air compressor can feel overwhelming.
With so many brands, models, and prices on the market, it’s easy to make the wrong choice.
Here are the three most common mistakes buyers make—and how to avoid them.

❌ Mistake 1: Focusing Only on Price, Ignoring Energy Costs

Many buyers ask first: “How much does it cost?”
But few ask: “How much electricity will it consume?”

Air compressors are true “power-hungry machines”—electricity can account for over 70% of the total lifecycle cost.
If you buy a low-priced, high-energy machine, the extra electricity bills you pay every year may cost as much as half a new unit.

✅ The Right Approach

Look at specific power (kW/m³/min) and efficiency class. The lower the number, the higher the efficiency.

Consider variable speed drive (VSD) compressors. They may cost more upfront, but in facilities with fluctuating air demand, they deliver outstanding energy savings.

💡 Chanun Recommendation
Chanun’s high-efficiency VSD screw compressors are designed with advanced energy-saving controls, delivering significantly lower operating costs and helping factories improve productivity while reducing expenses.

❌ Mistake 2: Oversizing the Compressor

Many believe “bigger is better.” But oversizing brings hidden costs:

Higher unloaded energy loss: frequent idle running wastes electricity;

Higher purchase price: unnecessary upfront investment;

Higher maintenance cost: larger machines mean more parts and more expensive service.

✅ The Right Approach

Carefully evaluate your actual air demand;

Calculate the total consumption of all pneumatic equipment, add diversity factors and line losses, and leave only a 10–15% margin;

If unsure, consult professionals for a proper air audit.

💡 Chanun Support
Chanun provides free air station assessments and system design services, ensuring you get the right machine—not just a bigger one.

❌ Mistake 3: Overlooking Air Treatment and Piping

Buying a compressor alone is not enough. The quality of compressed air directly affects equipment life and product quality.

Without proper dryers, filters, or piping, you may face:

Rust and damage inside valves, cylinders, and tools;

Quality issues in painting, food, or pharmaceutical applications;

Air leaks in poor piping systems—the biggest source of wasted energy in air systems.

✅ The Right Approach

Match air treatment equipment (air receivers, dryers, filters) to your quality requirements;

Use high-quality piping systems such as aluminum alloy, which deliver long-term efficiency and reliability gains far greater than the initial cost.
