The E2M1.5 is a compact, oil-sealed, two-stage rotary vane vacuum pump designed to deliver reliable and efficient vacuum performance for laboratory and small industrial applications. With a pumping speed of 1.6 m³/h and an ultimate pressure of 1.5 × 10⁻³ mbar, it provides a stable and powerful solution for processes that require a deep and consistent vacuum.
The two-stage design ensures improved ultimate vacuum performance and efficient gas handling. The pump features a compact build, low noise level of 54 dB(A), and easy maintenance, making it particularly suitable for sensitive laboratory and research environments.
The E2M1.5 is compatible with ULTRAGRADE™ Performance 15 oil and equipped with an NW10 inlet flange. Its robust construction, high reliability, and long maintenance intervals make it a cost-effective choice for applications requiring continuous and stable vacuum performance.
