Exhaust Hood

Definition

An Exhaust Hood is usually a square or rectangular hood housing an exhaust fan, designed to withdraw fumes, dust, or odors from an enclosure.

Purpose

The purpose of an Exhaust Hood is to capture and contain airborne contaminants, such as smoke, steam, and grease, and remove them from the air through an exhaust fan. This helps maintain a clean and safe environment, particularly in kitchens and industrial settings.

Examples of Use

• Commercial Kitchens: Capturing cooking smoke and grease to maintain air quality and hygiene.
• Laboratories: Extracting hazardous fumes generated during experiments or chemical processes.
• Manufacturing: Removing dust and airborne particles from work areas to protect workers and equipment.

Related Terms

• Range Hood: A type of exhaust hood used in kitchens to remove cooking odors and grease.
• Ductwork: The system of ducts that transports air from the exhaust hood to the outside.
• Fume Hood: A type of hood used in laboratories to safely ventilate hazardous fumes.

Notes

• Exhaust hoods should be regularly cleaned and maintained to prevent buildup of grease and contaminants.
• Proper installation and ventilation design are key to the effectiveness of exhaust hoods.
