Product Description
The Pfeiffer UNO 30M Rotary Vane Vacuum Pump is a single-stage, oil-lubricated pump designed for reliable performance in low to medium vacuum applications. As an upgraded replacement for the discontinued UNO 2.5, it offers a compact design, 30 m³/h at 50 Hz or 35 m³/h at 60 Hz pumping speed, a magnetically coupled single-phase motor, integrated gas ballast, and a built-in high-vacuum safety valve. Compatible with multiple motor voltages, it’s well-suited for global use in lab, industrial, and research settings.
