Advantages of the 3-lobe-blower
with pre-inlet channels
• Pulsations are cancelled directly in the blower stage
• The vibration loading of the bearings, timing gears and casing is
much more lower than regarding a two-lobe-blower
• The noise energy in the discharge piping is about 25 dB lower
• Lower investment outlays for buildings and system components

<Radial Foil Bearing >
The Air Foil Bearing for High Speed Turbo Blower
<Thrust Foil Bearing >
• Very little vibration
• Very little friction
• Permanent life time
The coating on surface of
bearing is very important for
life time.

First Step to Industry 4.0
20
Are YOU prepared for Industry 4.0….
....but how can we be part of it ???
Give the customer the best and latest interface options
Give the customer the possibility to get process information everywhere he wants
![Page 21: Technical Seminar --- Optimizing Efficiency in WWTP](https://reader031.vdocuments.us/reader031/viewer/2022020623/61f0193cdd8e4a073656eb38/html5/thumbnails/21.jpg)
Water 4.0 – pre-conditions & opportunities
21
Pre-conditions
digitization
automation
connectivity
Opportunities
increase of resource & energy efficiency
cost reduction, increase of productivity
flexible and competitive water management
From data to value!
Climate change & business!
![Page 22: Technical Seminar --- Optimizing Efficiency in WWTP](https://reader031.vdocuments.us/reader031/viewer/2022020623/61f0193cdd8e4a073656eb38/html5/thumbnails/22.jpg)
Water 4.0 --- Requirements
Actual performance/process data
Transfer of error codes, operating hours, etc.
Alarm messages (via Email)
Vibration data
Planning of service by means of early due date
information
Presentation and evaluation of operating data / process
data in pre-defined time periods
Which information does the customer get?
