It consists of a casing, which encloses the opening, and a number of spherical floats.

There are round apertures in the horizontal plane of the casing, which enable air to pass through.

There is one sphere-shaped float located under each round aperture in the casing.

The floats are normally located at such a distance from the apertures that they do not reduce the space available for air to pass through these apertures.

The floats are placed in guides that allow them to rise and fall freely.

When water threatens to flow in through the vent, the floats rise and block the apertures, preventing the water from entering the ship.

The total size of the round apertures in the casing is equal to the size of the opening.

The “net” applied is for preventing insects and dirt from entering the cabin areas.

The closure allows to reduce the free flow area on ¼, ½, ¾ and to close the vent simply by pulling the handle. Do not screw it on, just pull or push.

    Hello, I am very interested in this product for my sailboat. I would like to however, duct the fresh air from this vent to the engine compartment. Does this system allow for any sort of ducting hose to attach to the interior side? Can it be modified and stay watertight to do so?
    Great looking products!

    Hi

    I’m looking at this product for a small lifeboat that needs to capable of surviving a capsize. Is this product adequate for that and could you send me some costs if so.

    Thanks
