Nicro Day/Night Solar Vent — 4" White
Keep your cabin fresh, dry, and mold-free without running wiring or draining your battery. The Nicro Day/Night Solar Vent uses a built-in solar panel to charge an onboard NiMh battery, delivering continuous airflow day and night — moving over 1,000 cubic feet of air per hour (24,000 cu ft per day).
Designed for boaters who want a set-it-and-forget-it ventilation solution, this 4" white vent threads directly into the included deck plate and can be removed from outside the boat without tools — ideal for seasonal storage or cleaning.

Parts Desk Insights
Best use case: Ideal for enclosed boat cabins, V-berths, and storage compartments where moisture and stale air accumulate. This vent is the go-to choice when you need passive-to-active ventilation without any electrical installation — perfect for sailboats, cruisers, and trailered boats left in storage. The intake/exhaust switch lets you push or pull air depending on your cabin layout, making it versatile for both warm-weather cooling and off-season moisture control.
