The VN2020 replaces the VN115/87plus and VN116/87plus. The VN2020 will be especially for 4- stroke engine marked. The VN301plus replaces VN215/87plus for the 2- stoke marked!
VISATRON VN2020 continuously and simultaneously evacuate crankcase atmosphere from each crankcase compartment between two main bearings.
The VN2020 use a header-suction-tube system for this purpose. The oil mist detector is positioned in the middle between two header-suction-tube sections located on the engine sides; from these sections, single-suction tubes branch off near the compartments. These tubes are considerably thinner than the header-suction tubes and they have a throttling effect. Owing to the large header-suction- tube diameter the vacuum and consequently the sample flow at each suction point remain virtually constant. The arrangement of the detector in the middle of the header-suction tube results in an optimally short sample running time in the tube system.
