What size mesh screen is recommended for air vents on storage tanks?

The recommended size for mesh screens on air vents for storage tanks is a 14 mesh size. This mesh size strikes an appropriate balance between allowing air to exchange freely while preventing contaminants such as dust, debris, insects, and other particles from entering the tank. Proper ventilation is crucial in storage tanks to maintain structural integrity and prevent pressure build-up while ensuring that the quality of the stored water or liquid remains high.

Choosing a finer mesh (like 16) may restrict airflow more, which could lead to pressure issues or inadequate ventilation. Conversely, a coarser mesh (like 10 or 12) could allow too many contaminants to pass through, compromising the cleanliness of the tank's contents. Thus, 14 mesh is optimal for maintaining both air flow and protection against particulate intrusion.
