Solatron Stainless Steel Solar Vent/Fan with Rechargeable Battery and Remote Power Switch for Boat, RV and More

These solar vents are designed to increase ventilation in a variety of spaces including boats, RV's, greenhouses, and any other area where air circulation is a problem. By using one or more vents, you can decrease or eliminate the damaging effects of mold, mildew, moisture, and excessive heat buildup.

These solar vents are easily installed in a 4.5" cutout and, best of all, they run off of the sun only. This means no wiring, no plugs, no noise, and no running cost whatsoever.

All models feature a rechargeable Ni-MH battery allowing the vent to run both under direct sun light and when no direct sun light is available. Also, all models have an on/off switch. The SVT-224SR model comes with a remote on-off switch (attached via a 15' cord) that allows the vent to be mounted in less accessible locations. The SVT-224SA model comes with a remote solar panel attached to a 15' cord allowing the vent to be installed in areas not under direct sunlight. The SVT-224S model is completely self-contained, with switch and solar panel on the unit itself.

Recommended number of vents: up to 24 sqft = 1 exhaust vent; up to 40 sqft = 1 exhaust vent and 1 intake vent; 40 sqft or larger = 2 exhaust vents and 1 intake vent.

Please note: these are not high-volume cooling fans for blowing air, rather they make passive ventilation active with gentle air movement.
