Vent air AIRVENTV 13-32 mm hose connection with valve

If the point where the cooling water is injected into the exhaust is less than 15 cms above the waterline, then when the engine is Type V stopped, there is a risk that cooling water will siphon into the exhaust system and subsequently into the engine it self Such siphoning may be prevented by fitting a Vetus air vent at least 40 cms above the waterline. Two different models are available: type ASD and type AIRVENT. Both models can be connected to hoses with internal diameters of Ø 13, 19, 25 and 32 mm (½”,¾”, 1” and 1¼”). Version ASD38 connect to hose with internal diameter of Ø 38 mm (1½”).

Type V has a reliable antisiphon pressure valve and is self contained. However, it requires periodic maintenance to prevent clogging with salt crystals.

The only one in the market with virtually no maintenance. Can be easily dismantled by hand for cleaning.
