making innovation happen, together

NEG pumps have several unique characteristics which make them particularly attractive from high vacuum (HV) to ultra-extreme high vacuum (UHV-XHV).

Main features are:

• The highest pumping efficiency for hydrogen.
• Pumping speed for active gases does not decline at low pressure. Pressure as low as 10-14 mbar has been obtained using NEG technology.
• Very compact package, much more compact and lighter than any other type of pumps.
• The highest pumping speed per unit pump volume, vacuum system miniaturization is possible.
• Once activated they do not require power to operate.
• Vibration-free, ideally suited for electron microscopes, semiconductor inspection tools or vibration-sensitive equipment and systems.
• Negligible interaction with magnetic fields.
• Pumping of selected heavy hydrocarbons and organics possible.
• Large pumping speed and capacities also for air and H2O.


Moreover, starting from January 2016 SAES-RIAL Vacuum, a newly established company, partecipated by SAES Group and RODOFIL will supply, as a single provider, the complete finished product, the NEG coated chamber. The coated chambers will integrate the expertize in manufacturing, cleaning, NEG coating and testing of the two parent companies to deliver unsurpassed quality.
