What is the minimum size of corrosion-resistant screens for intake openings in commercial buildings?

The minimum size of corrosion-resistant screens for intake openings in commercial buildings is specified at 1/8 inch. This size is deemed sufficient to allow for adequate airflow while effectively preventing the ingress of larger debris and pests that could compromise ventilation efficiency or overall system performance. Additionally, a 1/8 inch screen is small enough to minimize the risk of corrosion issues brought on by external elements, thus maintaining the integrity and function of both the screen and the larger intake system over time.

Choosing a screen size larger than 1/8 inch could potentially allow more significant particles to enter the system, which could lead to clogs or damage. Conversely, sizes smaller than 1/8 inch may not provide the necessary structural integrity and could be more susceptible to corrosion or damaging impacts from the environment, which underscores the importance of adhering to the stipulated minimum size for corrosion-resistant screens in this context.
