FOSSA FO scroll vacuum pumps are everything that is expected from modern medium vacuum generation for today’s analytical and scientific applications.

They are the ideal solution for gas recovery or noble gas pumping systems, helium leak detectors, coating systems or backing of turbomolecular pumps. With their fully hermetic construction, they provide completely dry and reliable compression. Metallic bellows and static seals ensure tightness between the pumped medium and the ambient air. This avoids the contamination or leakage of the process gases. Having no shaft seals and coming with lifetime-lubricated bearings, FOSSA FO require very little maintenance. Servicing tasks are limited to changing the scroll tip seals. This can easily be done on site by the operator and without the need for special tools. Due to their low noise and vibration levels, they contribute to quiet working environments.
