<p>Vents are a must-have for any container. Our Carbon Steel Vents allow for multiple air exchanges during the heating and cooling cycle each day, helping to significantly increase air flow and reduce heat and moisture build-up inside your container. Each vent comes with an integrated bug screen, is powder coated dark gray and is designed to be bolt-on. NO welding and NO painting required! Adding vents to your shipping container will help prevent moisture build-up, eliminate dangerous fumes and chemicals that can lead to fire or explosion, and allow optimal airflow. Containers should be vented anytime household items, heavy machinery, automobiles, dry goods, chemicals and pressurized gases are stored inside. It is recommended for each container to have 2-6 vents, depending on the length of the container.</p>
