Becker SV5.330/1 4kW Side Channel Blower
The Becker SV5.330/1 is a single-stage industrial side channel blower offering 300 m³/h nominal airflow together with equal maximum vacuum and pressure differentials.
At 50 Hz, the 4kW configuration reaches -300 mbar maximum relative vacuum and +300 mbar maximum positive pressure. This gives the SV5.330/1 an unusually balanced performance profile for applications requiring substantial suction or discharge pressure.
Its regenerative, non-contact operating principle provides continuous oil-free process airflow for industrial machinery and air-handling systems.

Equal -300 mbar Vacuum and +300 mbar Pressure Capability
The defining characteristic of the Becker SV5.330/1 is the combination of 300 m³/h nominal airflow with equal maximum relative vacuum and positive-pressure capability. Rather than being particularly biased toward suction or discharge operation, this configuration provides up to 300 mbar differential on either side.
This makes the SV5.330/1 useful for industrial installations where substantial vacuum or pressure may be required from a single-stage blower design. The 4kW motor provides the power required to support this operating range.
The side channel principle differs from positive-displacement vacuum pump technologies. Air is accelerated by the rotating impeller and transferred repeatedly through the surrounding channel, increasing its energy progressively until it reaches the blower outlet.
Because the impeller operates without rubbing contact and there is no requirement for lubricating oil within the process-air chamber, the blower can provide a continuous supply of oil-free air for vacuum and pressure applications.
System design remains important. The actual operating airflow is determined by the intersection between blower performance and system resistance, so the required m³/h and working differential should be considered together when selecting a blower.

SV5.330/1 Performance and Operating Features
300 m³/h Airflow
Provides substantial process-air volume for machinery, conveying and industrial handling applications.
-300 mbar Vacuum
Strong suction differential supports more demanding vacuum handling and process applications.
+300 mbar Pressure
Matching pressure-side capability provides substantial differential for blowing and conveying duties.
Balanced Performance
Equal maximum vacuum and pressure figures make this model particularly versatile across different process-air requirements.
Oil-Free Operation
The compression process does not introduce lubricating oil into the process-air chamber.
Non-Contact Design
Airflow is generated by the rotating impeller without rubbing compression vanes or similar contact elements.
Where is the SV5.330/1 Used?
The balanced -300 mbar vacuum and +300 mbar pressure capability gives the SV5.330/1 considerable flexibility across industrial suction, blowing and process-air applications.
› Vacuum lifting and handling
› Printing and paper machinery
› Packaging and production equipment
› Vacuum hold-down systems
› Pneumatic conveying
› Drying and cooling air
› Aeration and blowing
› General industrial process systems
Replacing an Existing Becker SV5.330/1
Where the SV5.330/1 is installed on existing machinery, the blower model alone may not provide every detail needed to identify the correct replacement. Motor and electrical information from the complete nameplate should also be checked.
It is also useful to understand the original duty. Changes to filters, pipework, valves or the process itself can alter system resistance, meaning that a replacement blower may otherwise operate at a different point from the original installation.
Vacuum Pumps UK can review the existing blower information and application requirements to assist with replacement selection or a new side channel blower installation.
Becker SV5.330/1 Blower Accessories
Correct accessory selection can protect the SV5.330/1, control operating differential and help ensure reliable integration with the connected vacuum or pressure system.
Inlet Filters
Air filtration helps prevent dust and contamination from entering the blower and connected process-air path.
Vacuum Regulation
Vacuum relief devices can limit excessive suction differential and protect against high inlet restriction.
Pressure Protection
Pressure relief can help protect the blower where discharge restriction could create excessive differential.
Pipework Accessories
Silencers, flexible connections, non-return valves and connection components can be selected to suit the system.
