Rectangular Polished Anodised Aluminium Frame and
Naturally Anodised Grilles (ASVREC20)
The ASVREC20 Rectangular vent frame is polished and grilles are naturally anodised aluminium. Model number relates to the engine horsepower for which it is suitable.
A marine diesel engine needs sufficient air in order 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 to combustion air, the engine also requires sufficient ventilation air to dissipate the radiated heat. The volume of ventilation air required is about the same as the combustion air needed. The design of the VETUS air suction vents is based on these principles. The model numbers given in the table relate to the engine horsepower for which they are suitable. When designing the engine room layout, it is therefore easy to calculate the size of the air vents required. Do not forget to allow for extra vents to extract the heat from the engine space as well. For example: A boat with an engine of 60 hp will require for the 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).
