LOUVERED AIR SUCTION VENT TYPE SSVL

A marine diesel engine needs sufficient air to function correctly. The volume of combustion air required is approximately 6.1m³ per kW (4.5 m³ per hp) per hour, based on a maximum air velocity of 3m/sec. In addition, the engine requires sufficient ventilation air to dissipate radiated heat, with the volume of ventilation air needed being about the same as combustion air. The VETUS air suction vents are designed based on these principles. Model numbers relate to the engine horsepower for which they are suitable, simplifying the calculation of required air vent size during engine room layout design. Ensure to include extra vents for heat extraction from the engine space. For example, a boat with a 60 hp engine will require for combustion and ventilation air: 2 louvred air suction vents type 60 (1 x Starboard + 1 x Port) or 4 type 30 vents (2 x Starboard + 2 x Port). The frame is high gloss stainless steel (AISI 316), and the grilles are naturally anodised aluminium.
