Air Blower




RamdounPURE Water Air Blower System

The performance curves are based on air at a temperature of 15 °C and an atmospheric 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 confer with us.

Each G-2RB type can be applied both as vacuum pump and compressor in

Continuous operation over the total stated performance curve range. The

Motors are available as standard for the input voltage range of 50 and 60 Hz

And for protection category IP 55 as well as approbated for UL and CSA

 

50/60 Hz IP55 isolation material

The figures are without obligations.

Machines according to the ATEX norm 94/4 EG are available

 

Electromagnetic compatibility (EMC) EN55014-1/2, EN61000-2/-3/-4/-6.

1) For standard UL for ELECTRIC MOTOR UL 1004-1.

2) Relief-valve is available for limiting differential pressure.

3) Measuring-surface sound-pressure level acc. to DIN EN 21680, measured

At a distance of 1 m. The pump is throttled to an average suction pressure,

A hose is connected to the discharge side (compressor) / suction side

(Vacuum pump), but is not fitted with relief valves.

 

The motors are designed according to the DIN EN 60 034 / DIN IEC 34-1 and Temperature class F.

For the three phase machines the tolerances are +/- 10 % for fixed voltage and +/- 5 % for voltage range.

The single phase machines are designed with a +/- 5 % tolerances. If only 90 %

Of the maximum allowed pressure will be used for the continuous operating then

The allowed voltage range adds to +/- 10 %.

For all single and three phase machines which designed according to the UL and

CSA norm (UL 1004-1) the maximum allowed voltage tolerances are - 10 % resp. + 6 %.

The frequency tolerance is maximum +/- 2 %
