Fossa scroll vacuum pumps have been designed according to the latest single-sided scroll technology, combining dry compression with a fully hermetic construction. By adding the exceptionally low noise and vibration levels, these vacuum pumps are everything that is expected from modern medium vacuum generation for today’s analytical and scientific applications, where they have proven themselves for years.
Busch scroll vacuum pump design provides completely dry and reliable compression. Metallic bellows and static seals ensure tightness between the pumped medium and the ambient air, thus avoiding contamination or leakage of the process gases. This hermetic design makes Fossa scroll vacuum pumps perfectly suited for gas recovery or noble gas pumping systems.
They are the ideal solution for helium leak detectors, coating systems or backing of turbomolecular pumps. Being fitted with a gas-ballast valve, these vacuum pumps deliver unique vapour handling capabilities – the basic condition for drying processes.
Long service intervals and significant energy savings can be achieved through intelligent management of three frequency converter modes: “normal”, “boost” for an unrivalled pumping speed, and “idle” for unbeatable low noise and vibration levels.
Having no shaft seals and coming with lifetime - lubricated bearings as standard, Fossa vacuum pumps require very little maintenance. Servicing tasks are limited to changing the scroll tip seals which can easily be done on-site by the operator and without the need for special tools.
