The iSolar 50W108-FLEX Modular Solar Attic Fan is a high-efficiency solar-powered ventilation solution designed for both roof and wall mounting. This innovative fan easily retrofits into existing vent openings, making installation flexible and convenient. Utilizing solar energy, it operates a top-grade brushless motor for powerful yet quiet ventilation, helping to remove moisture to prevent the buildup of mold, mildew, and harmful gases while extending the lifespan of roofing materials. With the ability to reduce air-conditioner wear, balance indoor temperatures, and prevent ice-damming in winter, this fan provides an energy-efficient way to maintain a healthier and more comfortable environment.

*all 10” fans will not fit in a traditional 50 NFA vent cover and require a new larger vent cover. 


Notes: All multi-fan options are suitable for the Attic/Crawlspace combination venting option. See accessory specification sheet for more details. When selecting a system for retrofit into existing vents, please measure existing vents for fitment before ordering.                            
                            
Basis for Sq. Ft. CFM calculations. Range is based on columns below.                            
Powered attic ventilators – PAVs                            
                            
Powered attic ventilators should provide at least 10 air changes per hour. Multiplying the total square footage of the attic by 0.7 will provide the rate required. For particularly dark or steep roofs, we recommend a slightly higher rating.

 

Attic AreaMinimum CFM Required15% for Dark/Steep Roofs
<1,000 square feet700 CFM805 CFM
1,000 - 2,000 square feet1,400 CFM1,610 CFM
2,000 - 3,000 square feet2,100 CFM2,415 CFM
3,000 - 4,000 square feet2,800 CFM3,220 CFM

 

The air being exhausted must be replaced by outside air drawn through vents under the eaves in the soffit. To calculate the total minimum soffit vent intake area in square inches, divide the CFM of the PAV by 300 and multiply the result by 144.
