My garage doesn't have any soffit vents, how many will I have to drill for this fan to work properly?


This is a 1500 CFM roof vent so you will need at least 750 to 800 NFA (Net Free Area) of intake vents. Every intake vent has a NFA measurement. For example, you would need 14 pieces of Lowe's item # 17240 which is a 16x8 undereave vent and has 56 NFA. That would be 7 pieces on each side. If you have additional questions, please feel free to call me at 704-302-5575.
