The RB_series side channel ring blower feature voltage range moters for 50Hz and 60Hz in protection class IP55(insulation class
F) are CE, CCC approved. This makes them the ideal solution for world wide use. They can be used without any modifications
or test in Europe and Asia. The are mostly available ex stock. They are available for your requirements anytime.
G series operating principle
The impellers in the RB_series machines are mountes directly on the moter shaft for noncontact compression entirely without
friction. Maximum operational reliability, enven at high differential pressures. It ensured by the arrangement of the bearings
outside the compression chambar.
The gas is taken in through the inlet 1. The impeller 3 impacts the gas in the direction of rotation when gas enters the side
channel 2. Meantime, centrifugal force in the rotating impeller accelerates the gas outwardly, and pressure increases. As the
impellers go on rotating, the kinetic energy of the gas increases, resulting in further increasing of air pressure along
the side channel. The side channel becomes narrower at outlet 4, and the compressed gas is swept out of the impeller and
discharged out of the side channel blower.
Classics with innovative technology
With their high inlet volume flow up to 2,500m3/h and a differential pressure up to 780mbar, our low noise 2RB series allrounders have earned their reputation and convinced thousands of customers all over the world.
They are the first choice for many applications in related engineering due to high reliability, low-maintenance and long service time.
When used with a frequency converter, the performance of 2RB side channel blower can be increased considerably.
The 2RB series side channel blowers are CCC/CE approved and can be used without further testing all over the world.
Unsurpassed at highest differential pressure
Our revolutionary 4RB blower can create pressure difference of up to 1000mbar -- more than any other gas
ring pump. So far, the systems used to reach these differential pressure ranges were much louder and larger,
or subject to wear. Now theadvantage of wear-free operation coupled with a low noise level can also be used
in most demanding applications.
The 4RB series side channel vacuum pump/compressor can work up to 20,000 hours without maintenance
down time.
These specialist machines have proven their reliability under the harshest of conditions.
Their noise level was already impressively low, but our engineers and designers are able to make them even more quiet.
Operating conditions
Temperatures
Temperature of pumped gases:
max. permissible temperature: +40 °C [+104 °F]
Nominal value: +15 °C [+59 °F]
Pump-motor units for higher fluid temperatures on request.
Ambient temperature:
max. permissible temperature: +40 °C [+104 °F]
min. permissible temperature: -30 °C [-22 °F]
Nominal value:+25 °C [+77 °F]
Ambient temperatures between 25 °C [+77 °F] and 40 °C [+104 °F] affect the permissible total pressure difference (see Section "Permissible total pressure difference"). At higher temperatures the winding may be damaged and the grease change interval may be shortened.
Pressures
Min. inlet pressure: See rating plate.
Max. discharge pressure during compressor operation:See rating plate.
Max. permissible pressure in pump-motor unit:2 bar abs. [29 psia] At this pressure the operation of the pump-motor unit may be considerably impaired. Provide a corresponding protective device (e.g. pressure relief valve) if necessary.
Permissible total pressure difference: The total pressure difference specified on the rating plate only applies under the following conditions:
• Ambient temperature:25°C [77 °F].
• Inlet temperature (temperature of pumped gases at inlet connection):15°C [59 °F].
• Pressure: during vacuum-pump operation: 1,013 mbar [14.7 psia] at discharge connection; during compressor operation: 1,013 mbar [14.7 psia] at inlet connection;
At an ambient temperature of 40 °C [104 °F] the total pressure difference specified on the rating plate must be reduced by 10%. If the ambient temperature is between 25 °C [77 °F] and 40 °C [104 °F], then the total pressure difference specified on the rating plate must be reduced.
Installation altitude
Max. of 1,000 m [3,280 ft] above sea level.
When installing the pump-motor unit at an altitude of more than 1,000 m [3,280 ft] above sea level, first inquire with the Service department.
Electrical power supply:
Observe the rating plate.
It is imperative that the operating conditions correspond to the data given on the rating plate!
Deviations permissible without reduction in performance:
• ±5 % voltage deviation
• ±2 % frequency deviation
Connection to drive-motor terminal box:
Open the required cable entry openings on the terminal box. Here the following two cases are differentiated:
• The cable entry opening is prefabricated and provided with a sealing plug.
• Screw out sealing plug.OR
• The cable entry opening is closed off with a casting skin (only on pump-motor units with drive-motor axis heights of 100 to 160 in standard design).
• Break out casting skin using a suitable tool. For example, use a metal pin with a corresponding diameter or a chisel and hammer.
