Attwood 1488-5 Stainless Steel Louvered Vent for 3 Inch I.D. Ventilation Systems

The Attwood 1488-5 is a narrow stainless steel louvered vent built for boat intake and exhaust ventilation applications. It is constructed of all-welded #304 stainless steel with a polished finish, giving it corrosion resistance for long-term exposure to marine environments. The louvered design allows essential airflow through the hull while helping keep out rain, spray, and other unwanted elements, making it suitable for both engine compartment exhaust and general intake ventilation duty.

This vent is suitable for installation on any flat or most contoured hulls, and installation can be completed from either inside or outside the hull. It is sized for 3 inch inside diameter ventilation systems and is designed to pair with a collector box on the interior side of the hull to duct air to and from the ventilation system. Mounting is done with #6 fasteners. With a corrosion-resistant stainless steel build and a compact, low-profile footprint, the Attwood 1488-5 is a straightforward replacement or upgrade vent for boat owners maintaining proper engine compartment or below-deck airflow.
