Visatron VN215/87 Plus Oil Mist Detection System The Visatron VN215/87 Plus operates in a similar same way as the Visatron VN 116/87 Plus when it comes to a high oil mist alarm tripping. The Visatron VN215/87 Plus is able to indicate the suction point with the highest opacity, and thus the compartment in which the overheating damage has been done. The Visatron VN215/87 Plus has a single-suction-tube system, and each compartment is being connected by a separate tube to the valve box that is designed for 10 suction lines.
