Becker SV5.690/1 7.5kW Side Channel Blower
The Becker SV5.690/1 is a high-capacity single-stage side channel blower providing 720 m³/h nominal airflow for larger industrial vacuum and pressure systems.
At 50 Hz, the 7.5kW configuration reaches maximum relative vacuum of -320 mbar and maximum positive pressure of +280 mbar. This combination of high air volume and substantial differential gives the SV5.690/1 considerable capability in demanding industrial installations.
The blower uses non-contact regenerative compression to produce a continuous supply of oil-free process air without lubricating oil in the compression chamber.

720 m³/h Airflow for Larger Industrial Systems
The Becker SV5.690/1 represents a significant increase in air-moving capacity compared with the preceding SV5 single-stage sizes. At 720 m³/h nominal capacity, it is intended for applications where large volumes of air must be moved continuously through machinery, pipework or process equipment.
Its performance is not limited to airflow alone. Maximum relative vacuum reaches -320 mbar, providing strong suction capability, while maximum relative positive pressure of +280 mbar gives the blower substantial performance on discharge duty.
The regenerative side channel process repeatedly accelerates the air as it passes between the rotating impeller and annular channel. The repeated transfer of energy enables differential pressure to develop while maintaining a continuous air stream.
There is no requirement for oil lubrication within the process-air chamber, and the impeller operates without rubbing against the blower housing. This allows the SV5.690/1 to provide oil-free airflow for industrial processes where contamination from lubricating oil would be undesirable.
For a blower of this capacity, system design is particularly important. Pipe diameters, filtration, silencers, bends and restrictions should be considered carefully because excessive resistance can substantially alter the operating airflow and increase blower load.

SV5.690/1 Performance and Design
720 m³/h Capacity
High nominal airflow supports larger machinery, conveying systems and industrial process-air requirements.
-320 mbar Vacuum
Strong suction differential provides capability for demanding vacuum handling and extraction duties.
+280 mbar Pressure
Substantial positive-pressure performance suits larger conveying, blowing and aeration systems.
7.5kW Motor
Provides the power required for the combination of high airflow and significant differential performance.
Oil-Free Air
Lubricating oil is not introduced into the process-air chamber during normal blower operation.
Regenerative Compression
The non-contact impeller and side channel generate continuous airflow without rubbing compression components.
Applications for the Becker SV5.690/1
With 720 m³/h nominal capacity, the SV5.690/1 is suited to larger-scale applications where both airflow volume and the ability to overcome system resistance are important.
› High-volume vacuum handling
› Printing and paper machinery
› Packaging and production lines
› Industrial vacuum extraction
› Pneumatic conveying and material transport
› Large drying and cooling systems
› Aeration and process blowing
› General industrial process-air systems
Replacing or Selecting an SV5.690/1
When replacing an existing Becker SV5.690/1, supplying the complete information from both the blower and motor nameplates helps confirm the installed configuration and electrical requirements.
For new applications, the 720 m³/h nominal capacity should not be considered independently of system differential. The airflow available at the actual working vacuum or pressure will depend on the blower performance characteristic and resistance within the installation.
On higher-volume systems, correctly sized pipework can be especially important. Undersized pipework or excessive restriction can create unnecessary differential, reduce available airflow and increase operating temperature.
Vacuum Pumps UK can assist with application review, replacement blower identification and selection of an appropriate Becker side channel blower.
Becker SV5.690/1 Blower Accessories
Accessories can be selected to protect the SV5.690/1, control its operating differential and connect the blower correctly to larger industrial vacuum or pressure systems.
Inlet Filtration
Appropriate filtration helps prevent airborne particles and process contamination entering the blower.
Vacuum Regulation
Vacuum relief can help control suction differential if system resistance rises above the intended duty.
Pressure Protection
Pressure relief devices can protect against excessive discharge differential on positive-pressure applications.
Connection Components
Silencers, flexible connectors, non-return valves and correctly sized pipework can assist with system integration.
