LOUVRED AIR SUCTION VENTS

In addition to combustion air, an engine also requires sufficient ventilation air to dissipate the residual heat. The required volume of
ventilation air is about the same as the combustion air needed which is approximately 6.1 m per kW (4.5 m per hp) per hour based

on a maximum air velocity of 3 m/sec. The design of these VETUS air suction vents is based on these principles. The model numbers
(see tables below) relate to the engine horsepower for which they are suitable. So for example, a 40HP engine could use
1 x type 40, or 2 x type 20 vents.
