These stainless steel vent grilles are designed to ensure reliable airflow throughout your boat while also enhancing its aesthetics. Made from marine-grade AISI 316 stainless steel with a polished finish, they not only look great but also withstand years of saltwater exposure without rusting or pitting. The grilles feature a louvered design – the slats are angled to block direct ingress of rain or spray into the opening. This means even in rough conditions, the vents help keep water out of your compartments while fresh air continues to circulate and ventilate the space.
They are offered in two sizes to meet different needs: the smaller version (L=203 mm) is perfect for compact areas or smaller boats, whereas the larger one (L=320 mm) provides greater airflow and suits bigger compartments. Both models share a standard height of 108 mm, simplifying the selection process for replacements or new installations. Installation involves cutting an appropriate hole in a bulkhead or panel and securing the grille with screws (screw holes are pre-drilled on the flange). Once installed, the profile is low and smooth with no sharp edges – you won’t snag clothing or ropes on them as you move around on board.
- Small Size (20 cm): Great for ventilating small cabins, lockers, or electrical enclosures. For instance, mount this grille on a battery box lid to vent hydrogen gas, or on a head (bathroom) door in a compact boat to provide constant fresh air. It’s also useful for galley cabinets or wardrobe closets on smaller vessels to prevent mustiness.
- Large Size (32 cm): Ideal for engine rooms, large storage lazarettes, or galley areas on bigger boats and yachts. Most powerboats and sailboats over ~7–8 meters can use the large grille for the main engine compartment vents, aiding in cooling and fume extraction. It’s also excellent for salon areas that need extra ventilation.
- Universal Application: Though designed for boats, these stainless vents can be used on RVs, campers, or outdoor utility boxes – anywhere you need weather-resistant ventilation with an attractive look.
- Installation Tip: Use stainless steel screws for fastening to maintain full corrosion resistance. If mounting on a horizontal surface, apply a thin bead of marine sealant under the screw heads or flange to prevent any water seepage around the fasteners.
- Improve Comfort: By installing ventilation grilles, you reduce condensation and odors in closed spaces. This leads to longer life for equipment (electronics, fabrics) and greater comfort for crew and passengers by keeping air fresh and dry.
