These draw the air OUT! As air passes through the vent it creates a vacuum and draws the air from inside. Perfect for any Van, Bus, Caravan, Truck, Trailer or Float. High quality PVC Plastic, this low profile aerodynamic design only protrudes 50mm above roof. Simple installation, just cut a 120mm hole and place the vent over the top with the larger end of the teardrop shape facing forward.
