Sea-Dog 316 Stainless Steel Recessed Louvered Vent 331201 for Collector Box Air Intake

The Sea-Dog 331201 is a recessed louvered vent built to work together with a collector box to draw fresh air in and let exhaust air out on a boat. Instead of sitting proud of the surface, its louvers are recessed to create a flush surface area, which cuts down on damage to the vent itself and helps prevent chafing to mooring lines, fishing lines, and other rigging that might rub against it. The vent is stamped from 316 stainless steel, a marine grade alloy chosen for its resistance to corrosion in saltwater environments, so it holds up to long term exposure on deck or hull surfaces.

Vent area is 7.6 square inches, giving it a defined airflow capacity for use in engine compartment or storage area ventilation systems. It installs with six #6 RH fasteners, which are not included and must be purchased separately. The 331201 is sold individually (1 each per pack).

This vent is designed for use alongside a Sea-Dog collector box (part numbers 331202, 331203, or 331204) to complete an air intake and exhaust system. It can also be paired with the injection molded ABS louvered vent options in the same collector box lineup, giving installers flexibility in choosing a stainless or molded vent depending on the application.
