Which of the following dehydrators or combination filter/driers features a core that can be replaced when the desiccant becomes saturated with moisture? Illustration GS-RA-10
AI Explanation
The correct answer is A.
The illustration GS-RA-10 indicates that option A features a core that can be replaced when the desiccant becomes saturated with moisture. This is a key feature of certain dehydrators or combination filter/driers used on vessels, as it allows for easy maintenance and replacement of the desiccant material rather than requiring replacement of the entire unit.
The other options B, C, and D do not specify a replaceable core, and therefore would not meet this important criterion for a dehydrator or filter/drier used on a vessel covered by the US Coast Guard Captain's License Examinations.
