SEAFLO Solar Ventilator Fan – 900 CFM, 1.2W Solar, Waterproof

The SEAFLO Solar Powered Ventilator Fan delivers reliable, maintenance‑free airflow for marine and RV interiors. With a powerful 900 cubic feet per hour (CFM) capacity, this unit keeps cabins, cabins, and trailers cooler and more comfortable, even in the hottest climates.

Powered by a 1.2W solar panel, the fan operates autonomously, drawing energy from the sun and storing excess power in an internal battery. The integrated on/off switch lets you control airflow with ease, while the fan can run up to 30 hours on battery alone—ideal for overnight trips or cloudy days. Its waterproof design and low‑noise operation make it a quiet companion in any enclosed space.

Installation is straightforward: the fan’s 4‑3/4″ cutout diameter fits standard openings, and no electrical wiring is required for solar mode. The ABS plastic housing is durable and lightweight, and the unit comes with interchangeable intake and exhaust blades so you can choose to bring fresh air in or exhaust hot air out. With a 4‑year limited warranty, SEAFLO ensures long‑term performance for boats, yachts, RVs, trailers, and caravans.
