What role do dampers play in balancing kitchen exhaust systems?

• A. They regulate airflow, help balance exhaust with makeup air, and isolate sections for cleaning or maintenance.
• B. They seal off the system permanently.
• C. They increase the fan speed automatically.
• D. They filter air in the kitchen.

Answer: (A)

Dampers regulate airflow in kitchen exhaust systems, help balance exhaust with makeup air, and allow sections to be isolated for cleaning or maintenance. By adjusting how much air can pass through different parts of the duct, dampers fine-tune the relationship between the exhaust pulled from the hood and the makeup air supplied to the kitchen. This balance prevents negative pressure, reduces energy waste, and helps maintain proper ventilation performance. When cleaning or servicing, dampers can be closed to isolate a portion of the ductwork, allowing work to be done without shutting down the entire system. They are not meant to permanently seal the system, they do not automatically increase fan speed, and they do not filter air.
