What is a fire damper in HVAC?

A fire damper is installed in HVAC ductwork to close automatically during a fire and help slow the spread of flame, smoke and hot gases through ducts.

What is the difference between an air diffuser and a ventilation grille?

An air diffuser distributes supply air into a room, while a grille is often used for supply, return or exhaust air openings. Both are HVAC air terminal products.

Is a volume control damper the same as a fire damper?

No. A volume control damper adjusts airflow, while a fire damper is a fire safety device installed at fire-rated barriers.
