The E2M18 is a powerful, oil-sealed, two-stage rotary vane vacuum pump designed for demanding industrial and scientific applications. With a pumping speed of 17.7 m³/h and an ultimate pressure of 1.0 x 10⁻³ mbar, it delivers outstanding vacuum performance for processes requiring a stable and deep vacuum environment.
Thanks to its two-stage design, the pump ensures efficient gas handling and rapid evacuation. It is suitable for a wide range of applications, including research laboratories, vacuum packaging, freeze drying, coating processes, and other industrial operations that require reliable vacuum technology.
The E2M18 stands out for its compact and robust construction, low noise level of 57 dB(A), and ease of maintenance. It is compatible with ULTRAGRADE™ Performance 19 oil and features an NW25 inlet flange. With high reliability and long service intervals, it offers a cost-effective solution for continuous operation in demanding environments.
