Leybold RUVAC WH / WHU 7000 Roots Vacuum Blower - REBUILT

The RUVAC WH and RUVAC WHU are Roots boosters driven by water cooled hermetically sealed motors. The WHU types have a pressure balance line between the discharge and intake flanges. The RUVAC WH and WHU are lubricated with synthetic oil or perfluorized polyether (PFPE). Only specially prepared RUVAC WH / WHU PFPE pumps can be used for pumping oxygen greater than atmospheric concentration. Only RUVAC WH / WHU PFPE pumps can be used for pumping very aggressive or hazardous gasses.

Noise level acc. to DIN EN ISO 2151 < 63 dB(A)5)

1) The permissible pressure differences are dependent on various factors.

2) ± 10%, Low voltage option available for the 11 kW motor.

3) Minimum permissible speed: 1,200 rpm for operation over a period of over one hour

4) Higher ambient temperatures are permissible in consideration of reduced operating limits (derating). For details please consult Leybold.

5) Valid for 50 Hz operation under ultimate pressure conditions. Higher rotational speeds and especially pressure levels above 10 mbar will result in higher noise levels.

6) At operation with RUVAC frequency converters the drive efficiency in Europe is equivalent to the efficiency class IE3. Operating the RUVAC WH without the RUVAC frequency converter the efficiency corresponds to efficiency class IE2.
