Product Description
Ventilation for buildings with no power running to them
A 25 W panel plugs straight into the fan. Sun starts it, cloud slows it, dusk stops it. No outlet, no trench, no electrician.
Airflow tracks daylight. Hottest hour, hardest pull.
No battery — it does not run after dark.
By three o'clock, the air stops moving
A closed coop turns into an oven. Ammonia and moisture settle at floor level, and the birds go quiet and stop eating.
Same story under glass: trapped humidity, condensation on the glazing, mildew creeping up the lower leaves. The obvious fix is a fan. The problem is there is no outlet out there — and running one costs more than the fan ever will.
Three steps, one afternoon, ordinary tools
Fit the fan
Wall, roof, or a vent hole you already have. Brackets, screws, anchors and ties are in the box.
Angle the panel
Tilt it into the sun on its adjustable stand, within 16 ft of the fan. One DC plug joins the two.
Leave it alone
No inverter, no controller, no switch to remember. Light on the panel is the whole operating system.
What this fan will not do
Direct solar drive buys you a free install. It costs you control. If any line below is a dealbreaker, buy a thermostat unit instead — you will be happier and we will have fewer returns.
- Daylight only No battery. It will not run after dark or bank charge for a grey week.
- No thermostat It answers to sunlight, not temperature. You cannot set a trigger point.
- One fan, one panel Quoted at 220 CFM. Right for a small structure, not for a barn.
- 16 ft of cable The panel has to live within that distance of the fan. There is no extension.
- Wants direct sun Dappled shade under a tree will drop output noticeably.
