Solar Attic Fans for Crawlspaces

Our FLEX line solution offers a 20, 50, or 80-watt fully-adjustable, monocrystalline all-black solar panel with a single 6”, 8”, or 10” DC axial fan with brushless motor in our patented mounting plate. For crawlspaces, these can be installed on the sidewall between the floor joists with our fan adapter kit which includes a weather and wind resistant vent cover with animal guard. The solar panel can be remotely mounted up to 20’ away on the sidewall or roof using our included extender cord.

All of our solar attic fan motors come with IP68 weatherproofing to prevent premature failure. Some models also come with an optional AC adapter and Smart Switch with integrated thermostat for 24/7 operation based on temperature.

Proper crawlspace ventilation provides a greater level of mold or mildew prevention while also bringing more consistency in temperature under the floor of your home.
