Edwards Vacuum nXDS dry scroll pumps have increased pumping speeds, lower ultimate pressures, reduced noise, and lower power consumption. A key feature is a variable frequency motor which reduces the RPM’s once the ultimate pressure is reached, and increases RPM as the process and pressure dictates, thus saving energy and wear on the tip seal and mechanical components.
The tip seal is made of leading technology material that significantly extends life. Additionally the tip seal can be easily replaced by the end user in about 30 minutes.
A gas ballast permits pumping of condensable vapors including water vapor and solvents, opening a new range of applications that were previously off-limits to dry scrolls.
