Description
The Leybold Trivac D4B Vacuum Pump is reliable and designed for long service life, with a focus on durability. Despite some cosmetic defects and missing power cable, this used unit offers significant value due to its high functionality. It features a built-in oil pump for force-feed lubrication, minimizing wear and surface corrosion with non-ferrous metal components. The unit operates quietly with low vibration and modern vacuum technology, achieving high pumping speeds and low ultimate pressures with sustainable water vapor tolerance. Adaptable for continuous operation up to 1000 mbar, the pump is equipped with horizontal or vertical intake and exhaust ports, a pressure-controlled anti-suckback valve, and multiple O-rings made of elastomer FPM. Though previously used, the Leybold D4B maintains its utility in scientific and industrial applications, being environmentally friendly and compact with an air-cooled system and retractable handle for easy maneuvering. Computer is not included.
