ASVREC 20 Rectangular air suction vent

Description

Louvred air suction vent. Type ASVREC, rectangular louvred air suction vent The frames of this type are made of polished anodised aluminium and the grilles of naturally anodised aluminium. 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 m3 per kW (4.5 m3 per hp) per hourbased on a maximum air velocity of 3 m/sec. The design of these VETUS air suction vents is based on these principles. The model number 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.
