Leybold expands its Ecodry plus product family of dry multi-stage Roots vacuum pumps for laboratory, research and development and analytical applications. The current Ecodry 40 and 65 plus models are now joined by the new, smaller pump sizes Ecodry 25 and 35 plus. Leybold thus completes its range of quiet, low-maintenance and economical fore-vacuum pumps and fills the gap between Scrollvac 18 plus and Ecodry 40 plus.
A characteristic of the new product that is particularly important in research facilities and in analytical laboratories, is its low noise level. "Customers have already appreciated the existing models for this ergonomic advantage. The new Ecodry 25 and 35 plus also have a particularly compact design," says product manager Alexander Kaiser, naming another important feature. Thanks to technical optimisations, the vacuum pumps are smaller and more energy-efficient than competitive products. "As a result, we achieve very high pumping speeds with relatively little footprint, which means that a chamber can be evacuated more quickly and a lower ultimate pressure is achieved," summarises Kaiser.
A further advantage of the new unit is that it emits neither oil vapour, nor particles. This is particularly important in research institutes and laboratories where a clean working environment is essential. The oil-free multi-stage Roots pumps Ecodry 25 and 35 plus also have a maintenance interval of five years, during which time they run without any servicing. No oil to check and change so users can devote themselves fully to their research and laboratory work.
