The nXQ55i is designed for environments where gas containment is essential, providing a remarkably low leak rate < 5×10⁻⁸ mbar·l/s.
Its Multistage Roots design provides an dry, dust-free environment, enabling clean operation for sensitive applications.
The nXQ55i is optimised to support gas retention and minimise contamination, which is particularly useful in helium recirculation systems.
With a focus on reliability and system integrity, it provides a robust solution for advanced applications such as:
