EFFICIENT, COMPACT, EASY-TO-INSTALL SOLAR VENT FAN SOLUTIONS FOR HOME, GARAGE, CABIN & SHED VENTILATION PROBLEMS
Attic soffit vents, under the roof eaves and overhangs, are generally recognized as the best type of passive attic ventilation. They allow the attic to "breathe" without leaks and wind damage risks. In some cases, wind driven cross flow of air through the soffit vents is all the ventilation the attic needs. If it isn't enough, Solar Powered Soffit Fans are the best type of powered attic ventilation, using the same soffit vents and the sun to naturally ventilate the attic. Solar Powered Soffit Fans blow fresh air IN horizontally across the bottom of the attic, just above the ceiling, where it matters most. Hot air is displaced and forced OUT of the other attic vents, including soffit and roof vents, without using exhaust fans, reducing the attic temperature and moisture.
Fewer airflow CFMs are needed than with roof and gable fans. Solar Powered Soffit Fans can be used with shingle, tile, and metal roofs without problems, because they are not located on, or attached to, the roof. Solar Powered Soffit Fans work with your existing attic vents and improve the attic ventilation and cooling, using free power from the sun. Solar Powered Soffit Fans also enhance the performance of existing attic and gable vent fans, ridge vents, gable vents, turbines, J and mushroom vents, etc. For enclosed cathedral ceilings, they can be arranged to move air in each rafter bay in the gap between the roof and the ceiling insulation.
CSF Solar Crawl Space Fans exhaust crawl space moisture and odors, using existing foundation vents. Bad air is gently and evenly pulled out of the crawl space through a foundation vent and replaced by fresh air entering through the other foundation vents.
Also ideal as off grid ventilation for smaller areas such as sheds, garages, cabins, workshops, and other outbuildings and enclosures.
We also make custom synchronized push-pull (supply-exhaust) balanced cross-flow solar crawl space fans for larger spaces.
Custom solar powered fan solutions are a significant part of our business. Some past examples include -
