When calculating the free area necessary to meet the make-up air requirements of the enclosure, consideration must be given to the blockage effects of louvers, grills and screens.

Screens must have a minimum mesh size of 1/4" (6.4mm). If the free area through a louver or grill is not known ducts should be sized per Table 1.
