Overview

Direct-Coupled Rotary Vane Vacuum Pump LMVU-A201 delivers 4 L/s pumping speed and reaches pressure down to 1.33 Pa. It runs at 1400 rpm and holds 1 L of pump oil. A gas ballast valve helps manage vapor in the oil, while double anti-return protection reduces oil backflow. It suits vacuum drying ovens, freeze dryers, printing machinery, and laboratory vacuum systems.
