The ATH series of hybrid turbomolecular pumps are no longer available as new and have been superseded by the next generation of turbomolecular pump. However they are still available as service exchange pumps. The pumping speeds ranging from 30 to 300 l/s. Some models have been optimised for instrumentation or R&D applications while others for heavy cycling applications. Alcatel’s knowledge of hybrid turbomolecular pumps has resulted in the design of the ATH series, optimising vacuum performance, electronics functionality and reliability. The ATH series also offers added value through features such as: • Intermediate vacuum ports • Efficient integration To cover a wide range of application requirements, multiple pump monitoring options are available from OEM boards to complete user friendly controllers.

ATH 31 Exceptional performance
An ultimate pressure of 10-10 mbar with a dry forepump. The ATH 31+ produces a 1011 compression ratio for N2 and a 105 compression ratio for H2. High compression ratios and high backing pressure tolerance (up to 45 mbar) produce very stable performance, ideal for analytical instruments. A 200 sccm flow rate at 0.5 mbar The ATH 31+ allows more than 200 sccm to be pumped continuously.

This mass spectrometer includes
two ATH 31 (integrated nude version)
and two miniboard controllers.

ATH 31
The ATH 31 includes one turbo stage and one Holweck stage. With excellent compression ratios and a backing pressure tolerance of up to 25 mbar, it can be backed by a membrane pump. It features one intermediate pumping port.

ATH 31+
The ATH 31+, with one turbo stage and three Holweck stages, offers outstanding compression ratios. It is the ideal version for pumping light gases. Its exceptional performance can be achieved with a membrane pump as a fore.

ATH 31 C
The ATH 31 C includes one turbo stage, and two Holweck stages. A purge offers protection against corrosive gases. It can be backed by a membrane pump. It features one intermediate pumping port.

ADVANTAGES
The patented designs of the ATH 31 and 300 allow integration of the pumps closer to the application, saving space and money. Additionally, the ATH pumps can be equipped with intermediate vacuum ports to offer application flexibility such as:

• Additional pumping capacity,
•Management of a pressure set point,
• Venting.

ROBUSTNESS
The low rotational speed and the machined rotors of the ATH series make these pumps very robust against:

• Unexpected air inrushes,
• Shocks,
• Gyroscopic effects,
• Bearing failures.
