What is the most probable cause of reduced capacity in a reciprocating air compressor?

🔍 Key Concepts

• Reciprocating air compressor normal operation and airflow path • Common faults that directly reduce delivered volume (capacity) vs those that mainly affect pressure or temperature • How leakage vs restriction vs control devices change compressor output

💭 Think About

• Which of these problems would cause the compressor to move LESS free air for every stroke, even if it is still running at the same speed? • Which option would most directly affect how much air actually gets in and out of the cylinder on each stroke? • For each choice, ask: does this mainly cause overheating, high pressure, control malfunction, or true reduction in volume delivered?

✅ Before You Answer

• Identify which component is in the direct flow path of the air being drawn in and discharged every stroke • Decide which fault would show up as reduced delivered CFM (cubic feet per minute) with the compressor apparently running normally • Separate issues that mostly cause overheating or inefficiency from those that primarily cut capacity/output
