1) To DIN 28 400 and subsequent numbers<br />
2) Permissible pressure difference are dependent on various factors. Please see manual for further details<br />
3) Higher ambient temperatures are possible with reduced operating limits. Please consult Oerlikon Leybold <strong>Vacuum</strong> for details<br />
4) Low voltage available as option for the 11 kW (14.75 hp) motor<br />
5) Min. permissible speed: 1200 rpm if run for more than 2 minutes<br />
6) Valid for 50 Hz operation under ultimate pressure conditions.<br />
Higher rotational speeds and especially pressure levels about 10 mbar (7.5 Torr) will result in higher noise levels<br />
