Which of the following devices captures grease and moisture before they reach the duct system in a kitchen?

The device that captures grease and moisture before they reach the duct system in a kitchen is the hood. Kitchen hoods, also known as exhaust hoods or range hoods, are specifically designed to ventilate cooking areas by removing airborne grease, smoke, odors, and moisture. They usually feature a fan and a filter system that effectively collects particulates and moisture produced during cooking, preventing them from being released into the duct system and ultimately contaminating the air or causing buildup within the ductwork.

In the context of a commercial kitchen or food service environment, the hood plays a crucial role in maintaining air quality and safety. It helps to minimize fire hazards by reducing grease accumulation in the ducts and contributes to a cleaner and more comfortable kitchen atmosphere for staff.
