Smoke Vents and Natural Ventilation - Metal Lid Smoke Vent - Series 3300

Series 3300 aluminum framed or galvanized steel framed metal lid smoke and heat vents are engineered to provide a path for hot gases and smoke to exit a building during a fire. Designed to perform under tortuous conditions, they can help minimize structural damage, reduce lateral fire spread, allow fire-fighters to determine the location of a fire by observing smoke plumes from open vents, and can reduce dangerous heat and vision-obscuring and potentially toxic smoke.
