The requirements for modern analytical instruments and systems are changing: users in laboratories and research facilities increasingly rely on low-noise, oil-free vacuum solutions to avoid contamination and, above all, unnecessary noise in laboratory environments. With the newly developed family of dry-compressing multi-stage Roots vacuum pump Ecodry plus, Leybold has launched a new fore-vacuum pump for the analytics market. The most striking competitive advantages, as the company points out: apart from its quiet and low-vibration operation, it features a modern, space-saving design with extremely powerful performance. The basic idea of the Ecodry plus was to develop a clean, compact and low maintenance pump in the size class 40 to 60 m3/h, as used in analytical or research laboratories. This pump class is positioned in the transition area between small laboratory equipment and large machines. The pump was developed to match the requirements for systems such as mass spectrometers and electron microscopes. It is also suitable for large-scale accelerators due to the absence of dust or oil contamination. It offers a high degree of comfort, suction power and flexibility. The pump family is available in the sizes 40 plus and 65 plus. The most important feature of this new vacuum pump range is the extremely low noise level. With an average value of 52 dB (A), it works below the noise limit that is harmful to human health. The sound level of the Ecodry plus is below a conversation at room volume. The non-contact rotor design is not only designed for a quiet operation, but also for energy-efficiency and low vibration. In order to be able to produce high-resolution images, such as in electron and scanning tunnel microscopes, the pump must not transmit vibrations. The elementary feature is that the rotors and the housing rotate without friction even at high speeds.
