1) The products that have customer specificities may have different characteristics.
2) Standard reference conditions: T0 = 273,15 K - P0 = 1013.25 hPa.
3) At nominal speed with 25 °C water cooling temperature.
4) With an exhaust pressure < 0.4 hPa, depends on external conditions (temperature, water flow rate, ambient tempera-
ture). For other conditions, contact us
5) Reduced maximum flow rate, ultimate pressure at exhaust without loss of flow rate speed. Depends on environmental
conditions.
6) With ISO-F flange (best with CF-F flange). Contact us.
7) This maximum temperature influences the maximum flow, contact us.
8) Up to 90 % of full rotation speed, with exhaust pressure < 0.1 hPa.

Environmental characteristics
15.2.2 Cooling water characteristics
The characteristics below concern only the turbomolecular pump with magnetic ball bearings. This
pump is associated with a backing pump. To ensure the effective operation of the application:
► Comply with the most restrictive characteristics for the installation.
► Make sure the water coming from the equipment does not freeze.
