Becker SV 500/2 4 kW Side Channel Blower
The Becker SV 500/2 4 kW is a double-stage side channel blower providing 260 m³/h nominal capacity together with strong vacuum and positive-pressure performance.
At 50 Hz it provides maximum relative vacuum of -410 mbar and maximum positive pressure of +370 mbar. At 60 Hz the corresponding 4.8 kW motor increases nominal volume flow to 305 m³/h, with -400 mbar maximum vacuum and +340 mbar maximum pressure.
The SV 500/2 therefore provides a useful step up in airflow while retaining the higher differential characteristics of Becker’s double-stage side channel design.

260 m³/h Double-Stage Vacuum and Pressure Performance
The Becker SV 500/2 4 kW combines a nominal 260 m³/h airflow with up to -410 mbar relative vacuum and +370 mbar positive pressure. It is designed for applications where a substantial volume of air must be moved while overcoming appreciable system resistance.
The /2 double-stage arrangement differs from a single-stage side channel blower by passing the process air through two successive compression stages. Additional energy can therefore be transferred into the air, allowing a greater pressure differential to be developed.
For vacuum duties this gives the SV 500/2 useful capability in handling, fixing, conveying and machinery applications where suction-side restriction is significant. On pressure duties, the same basic blower principle can provide process air for conveying, aeration, drying and similar industrial requirements.
Compression is non-contact and oil-free. There are no rubbing vanes within the process-air chamber and no lubricating oil is required in the compression path, helping provide clean airflow and relatively low routine maintenance requirements.
Blower selection should be based on the required volume flow at the actual working differential. The nominal 260 m³/h capacity alone does not describe the airflow available once vacuum or positive pressure develops within the system.
Becker SV 500/2 4 kW Technical Specifications
The 4 kW 50 Hz configuration provides 260 m³/h nominal capacity. At 60 Hz the corresponding motor rating is 4.8 kW and nominal flow increases to 305 m³/h.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 260 m³/h | -410 mbar | +370 mbar | 4 kW | 61.7–62.5 kg |
| 60 Hz | 305 m³/h | -400 mbar | +340 mbar | 4.8 kW | 61.7–62.5 kg |
Vacuum and pressure figures are relative. Becker lists 61.7–62.5 kg depending on the exact motor construction.
Key Features of the SV 500/2 4 kW
260 m³/h Airflow
Provides a substantial volume of process air while retaining the differential capability of a double-stage blower.
-410 mbar Vacuum
Strong suction capability suits vacuum applications with appreciable inlet or process resistance.
+370 mbar Pressure
Positive-pressure performance supports conveying, aeration, drying and other industrial process-air duties.
Double-Stage Design
Two successive side channel stages allow greater differential to be developed than a comparable single-stage arrangement.
Oil-Free Compression
No lubricating oil is required within the process-air chamber, helping provide clean airflow to the application.
Non-Contact Operation
The impeller compresses the air aerodynamically without rubbing compression elements in the air path.
Industrial Applications for the SV 500/2
The SV 500/2 4 kW is suited to applications requiring a combination of relatively high airflow and substantial vacuum or positive-pressure differential.
› Vacuum lifting and handling
› Vacuum fixing and clamping
› Printing and paper machinery
› Packaging machinery
› Automated handling systems
› Pneumatic conveying
› Aeration systems
› Industrial drying
› Cooling and process airflow
› General mechanical engineering
Becker SV 500/2 4 kW Supply and Selection
Vacuum Pumps UK can assist with SV 500/2 4 kW supply for replacement requirements, machinery installations and new industrial vacuum or pressure applications.
For an existing installation, send us photographs of the Becker blower and motor nameplates. This helps confirm the exact SV 500/2 configuration before quotation.
For a new application, provide the required airflow together with the normal operating vacuum or positive pressure. Significant pipework, filters, valves and other restrictions should also be considered when establishing the duty point.
The SV 500/2 should be selected from the airflow available at the required differential rather than from the nominal 260 m³/h figure alone.
Accessories for Becker SV 500/2 Installations
The connected system directly influences blower performance. Suitable filtration, relief protection and correctly sized pipework can help maintain the intended operating conditions.
Inlet Filters
Correctly sized filtration helps protect the blower while avoiding unnecessary suction-side restriction.
Vacuum Relief Valves
Vacuum relief can limit excessive differential if inlet restriction rises beyond the intended operating condition.
Pressure Relief Valves
Pressure relief can help protect the blower if a blocked or restricted discharge causes differential to rise.
Installation Accessories
Flexible connectors, non-return valves and correctly sized pipework can be incorporated into the complete installation.
Becker SV 500/2 Service, Repair and Spare Parts
Although side channel compression is non-contact, reliable blower operation still depends on the condition of the motor, bearings and impeller together with the operating conditions created by the connected system.
Dirty filtration, pipework restriction or process changes can increase differential and operating temperature. These external factors should therefore be checked whenever blower performance changes.
Vacuum Pumps UK can assist with Becker SV fault investigation, servicing and workshop repair.

Becker SV 500/2 4 kW Frequently Asked Questions
What airflow does the Becker SV 500/2 4 kW provide?
Nominal volume flow is 260 m³/h at 50 Hz and 305 m³/h at 60 Hz.
What is the maximum vacuum?
Maximum relative vacuum is -410 mbar at 50 Hz and -400 mbar at 60 Hz.
What positive pressure can the 4 kW version provide?
Maximum relative positive pressure is +370 mbar at 50 Hz and +340 mbar at 60 Hz.
What does the /2 designation mean?
The /2 identifies a double-stage blower arrangement. Process air passes through two side channel stages to develop increased vacuum or pressure differential.
Is the compression process oil-free?
Yes. The side channel compression chamber operates without lubricating oil in the process-air path.
Should the SV 500/2 be selected from its 260 m³/h capacity alone?
No. The required airflow at the actual working vacuum or pressure should be used when selecting the blower.
Can Vacuum Pumps UK identify an existing SV 500/2?
Yes. Send us clear photographs of the blower and motor nameplates and we can assist with identification, supply, servicing or repair.
