🔍 Key Concepts

• Low pressure air compressor operation and common failure modes • How lack of maintenance affects valve seating and cleanliness • Effects of speed, pressure, and filtration on valves and valve seats

💭 Think About

• Which choice most directly leads to valve seats and valve plates not sealing properly due to dirt, wear, or buildup? • Which options describe conditions that might damage other parts of the compressor (like bearings, pistons, or gaskets) more than the valves themselves? • Think about what normally causes a valve to leak: is it more often mechanical wear, contamination, or incorrect operating parameters?

✅ Before You Answer

• Identify which option is clearly related to progressive wear or fouling of the valves over time. • Check which choices would more likely cause overheating or mechanical failure, rather than leakage at the valve seats. • Verify that your selected option describes a long-term condition that would gradually cause valve leakage, not just a short-term operating change.
