Product details

Two standard sizes are abailable: FO 0015 A and FO 0035 A. Featuring consistently high vacuum levels and with very low noise and vibration levels, these vacuum pumps are ideal for today's analytical and scientific applications. Thanks to their compact design, Fossa scrool vacuum pumps require no special mounting. This makes setup quick and easy wile also providing a high degree of pump mobility.

  • Fossa scroll vacuum pumps are the perfect solution for backing of turbomolecular vacuum pumps. They are ideally suited for generating high vacuum in load lock or transfer chambers, helium leak detectors, mass spectrometers, electron microscopes and other analytical devices. They are also used in processes for handling of gases that require the highest level of purity within the gas recovery process.

    The low noise and vibration levels make Fossa vacuum pumps suitable for use in areas such as laboratories. With no shaft seals and with lifetime-lubricated bearings, Fossa vacuum pumps require very little maintenance. Their high level of efficiency ensures maximum suction capacity with low energy consumption. The standard gas-ballast valve enables the pumping of vapors.
