The cylinders and intercoolers of most low pressure air compressor's are cooled by __________.

Correct Answer: Option A — air

Low-pressure air compressors, typically used for ship service or control air, are frequently air-cooled. The compressor cylinders and intercoolers are designed with external cooling fins to dissipate heat into the surrounding engine room atmosphere. This design simplifies maintenance by eliminating the need for complex water-cooling piping and associated pump systems.
