What is the main purpose of a ventilator on a container?

The main purpose of a ventilator on a container is to allow for air exchange. This is particularly important for cargo that is sensitive to humidity or has the potential to release gases or vapors. By enabling airflow, ventilators help to prevent the buildup of moisture, which can lead to fungal growth, condensation, or damage to the cargo. They also allow for the dissipation of harmful gases that may accumulate during transport, ensuring that the environment inside the container remains stable and safe for the goods being transported. This function is crucial for maintaining the quality of perishable or sensitive products, ultimately contributing to better cargo preservation and reduced risk of spoilage.
