A top choice for turbos
With its superior performance and compact footprint, the SCROLLVAC 3S plus is a great alternative to diaphragm pumps. It is particularly well suited for backing the Leybold TURBOVAC i range of turbomolecular pumps. And with a base plate available as an accessory, it is easy to retrofit for users looking to upgrade existing systems to scroll technology.
Effective vapor handling
The built-in manual gas ballast on the SCROLLVAC 3S plus is capable of handling a fair amount of water vapor in the pumped gas load, while still maintaining a good ultimate vacuum. Configured for light gas pumping and low vapor load handling, the SCROLLVAC 3S plus can also be fitter with an optional adaptor for inert gases.
Quiet operation, low vibration
The SCROLLVAC 3S plus is optimized for quiet operation. Achieving low vibration of 4.5 mms-1 (in plane of bearing) and further isolated with a full fan cowl, users can count on quiet operation, which is particularly important in a laboratory setting. The SCROLLVAC 3S plus is also supplied as standard with a separate exhaust silencer filter for free-standing operation. Otherwise, an exhaust line can be fitted directly to the built-in push-fit exhaust fitting.
Reliable seal, secure performance
As with all larger Leybold SCROLLVAC pumps, the newest SCROLLVAC comes fitted with a built-in exhaust valve as standard, providing effective protection from rapid pressure rise. For extra system protection in the event of a power failure, the SCROLLVAC 3S plus also offers the added peace of mind of a fast-acting solenoid inlet valve* with a delay relay switch to preserve the vacuum inside the system.
*For users who already have protection valves built into their system, the pump can also be supplied without the inlet valve, for an even more cost-effective solution.
With its high build quality, outstanding performance, flexible design, and compact footprint, the SCROLLVAC 3S plus is ideally suited to smaller-scale laboratories and R&D applications.
