What is the purpose of an air compressor intercooler?
Direct Answer
Option C: Cool compressed air between stages to reduce volume, increase air density, and remove moisture
Multi-stage air compressors utilize intercoolers to cool compressed air between stages. Lowering air temperature reduces volume and increases density, improving volumetric efficiency while condensing out moisture to protect downstream starting air receivers from water accumulation.
