Becker SV7.330/1 4kW Side Channel Blower
The Becker SV7.330/1 is a single-stage side channel blower providing 290 m³/h nominal airflow with particularly strong positive-pressure performance from a 4kW motor.
At 50 Hz, maximum relative vacuum is -280 mbar while maximum positive pressure reaches +360 mbar. This combination gives the SV7.330/1 substantial operating differential for demanding industrial vacuum and pressure applications.
Its regenerative, non-contact compression principle generates continuous oil-free process airflow suitable for conveying, aeration, handling and production machinery.

290 m³/h with Strong Positive-Pressure Performance
The Becker SV7.330/1 combines 290 m³/h nominal airflow with a maximum positive pressure of +360 mbar. This gives the blower particularly useful capability where process air must be delivered against significant resistance within the connected system.
Vacuum performance is also substantial, reaching a maximum relative vacuum of -280 mbar. The same SV7.330/1 can therefore be applied to industrial suction duties as well as positive-pressure applications.
The side channel operating principle repeatedly accelerates air as it travels around the blower housing. Energy transferred by the rotating impeller progressively increases the differential between the inlet and outlet while maintaining a continuous flow of air.
Because the impeller does not rely on physical contact with the blower housing to create compression, the process-air chamber operates without lubricating oil. This makes the SV7.330/1 suitable for applications requiring clean, oil-free airflow.
System resistance remains an important part of blower selection. Filters, pipe diameter, bends, valves and process equipment all influence the actual working point, so both airflow and required differential should be considered when specifying the blower.

SV7.330/1 Performance and Design
290 m³/h Capacity
Provides substantial process-air volume for medium and larger industrial machinery and air systems.
-280 mbar Vacuum
Provides strong suction differential for vacuum handling, conveying and process applications.
+360 mbar Pressure
Particularly strong positive-pressure capability for conveying, aeration and demanding blowing duties.
4kW Motor
Supports the combination of useful airflow and high operating differential available from this configuration.
Clean Process Air
Oil is not required within the regenerative compression chamber, providing an oil-free process-air path.
Regenerative Compression
Air is progressively accelerated through the side channel rather than compressed by contacting vanes.
Applications for the SV7.330/1
With 290 m³/h airflow, -280 mbar vacuum and particularly strong +360 mbar positive-pressure capability, the SV7.330/1 can serve a broad range of industrial duties where both air volume and operating differential are important.
› Pneumatic conveying systems
› Packaging and production machinery
› Printing and paper handling
› Industrial vacuum handling
› Water waste aeration and process blowing
› Drying applications
› Cooling and air circulation
› General process-air systems
Becker SV7.330/1 Supply and Replacement
Vacuum Pumps UK can assist with replacement SV7.330/1 requirements for installed machinery and with blower selection for new vacuum or pressure applications.
For an existing installation, supplying photographs or details from both the blower and motor nameplates helps us identify the unit and assess the replacement requirement. Information about the process and connected system can also be useful.
Where the blower is being selected for a new application, the required airflow should be considered at the intended working pressure or vacuum rather than from nominal capacity alone. This is particularly important on higher-differential duties.
Becker SV7.330/1 Accessories
Suitable filtration, relief valves and connection components help protect the SV7.330/1 and allow its vacuum or positive-pressure performance to be controlled within the intended operating range.
Inlet Filtration
Correctly sized filters help protect the blower from contamination without introducing unnecessary airflow restriction.
Vacuum Regulation
Vacuum relief valves can control excessive suction differential and provide protection when system conditions change.
Pressure Protection
Pressure relief is particularly important where discharge resistance could cause the blower to operate beyond its intended duty.
Pipework Accessories
Silencers, flexible connectors, non-return valves and connection components can be selected for the installation.
Becker SV7.330/1 Service, Repair and Spare Parts
An SV7.330/1 that develops abnormal noise, vibration, increased operating temperature or reduced airflow should be investigated. Bearing condition and motor performance should be considered together with filtration, pipework and other factors within the connected air system.
