The performance curves are based on air at a temperature of 15 °C and anatmospheric pressure of 1013 mbar with a tolerance of

+/- 10 %.The total pressure differences are valid for suction and ambient temperatures up to 25°C. For other conditions please confirm with us.

Each 3RB type can be applied both as vacuum pump and compressor incontinuous operation over the total stated performance curve range. The motors are available as standard for the input voltage range of 50 and60 Hz and for protection category IP 55.

All 3RB fulfill the 2006/42/EC(machinery)and 2006/95/EC(low voltage) directives and the EN 60034-1 norm "Rotating electrical machines"

The motors comply with EN 60 034-1 / -2 /-30(IEC 60034) and thermal class F

The voltage tolerance is +/- 5%.

The frequency tolerance is +/- 2% maximum.

1)  Relief valves available for limiting differential pressure

2)  Measuring surface sound pressure level acc. to EN ISO 3744, measured with an equivalent unit at a distance of 1 m. The pump is throttled to an average suction pressure, with piping connected, but no relief valves fitted, tolerance ±3dB(A).

3)  Performance can different if standard motors are used. Please refer to corresponding data sheets.
