MINIMUM ATTIC INTAKE AREA REQUIRED
Sufficient intake area must be provided in the attic to assure that the fan will not be overloaded and that
it will deliver its rated CFM. This can be accomplished with some type of attic venting such as gable
louvers or under-eave vents. The table below shows the minimum intake area needed for each fan
installed.
