Becker SV 700/2 5.5 kW Side Channel Blower
The Becker SV 700/2 5.5 kW is a double-stage side channel blower providing 375 m³/h nominal capacity with strong vacuum and positive-pressure performance for industrial applications.
At 50 Hz it delivers maximum relative vacuum of -390 mbar and maximum positive pressure of +330 mbar. At 60 Hz the corresponding 6.6 kW motor increases nominal capacity to 435 m³/h, with maximum vacuum of -340 mbar and maximum positive pressure of +250 mbar.
The combination of higher airflow and double-stage compression makes this SV 700/2 configuration suitable where a substantial volume of process air must be moved against significant system resistance.

Higher Airflow with Double-Stage Differential
The Becker SV 700/2 5.5 kW is designed for applications where a comparatively large volume of air must be moved while still overcoming meaningful vacuum or discharge resistance. Its nominal 375 m³/h capacity is combined with -390 mbar maximum relative vacuum and +330 mbar maximum positive pressure at 50 Hz.
This gives the blower a different performance profile from a low-pressure fan or a single-stage side channel unit. The /2 arrangement passes the process air through two successive stages, allowing additional differential to be generated while maintaining useful airflow.
On vacuum duty, the SV 700/2 can be applied where suction is required for handling, fixing, conveying or other industrial processes. On positive-pressure duty, the same blower design can supply air for conveying, aeration, drying and other process applications.
The compression process is non-contact and oil-free. No lubricating oil is required in the air chamber and there are no rubbing vanes within the compression path, helping provide clean process air and relatively low routine maintenance.
As with any side channel blower, the duty point is important. Pipe length, pipe diameter, filters, valves and process restrictions all affect the differential developed and therefore the volume flow available within the installed system.
Becker SV 700/2 5.5 kW Technical Specifications
At 60 Hz the corresponding motor rating is 6.6 kW and nominal volume flow increases to 435 m³/h. Maximum relative vacuum is -340 mbar and maximum positive pressure is +250 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 375 m³/h | -390 mbar | +330 mbar | 5.5 kW | 89 kg |
| 60 Hz | 435 m³/h | -340 mbar | +250 mbar | 6.6 kW | 89 kg |
Vacuum and pressure figures are relative. Weight is 89 kg including motor.
Key Features of the SV 700/2 5.5 kW
375 m³/h Capacity
Provides substantial process-air volume while retaining the differential advantages of a double-stage blower.
-390 mbar Vacuum
Strong 50 Hz suction capability suits vacuum installations with appreciable system resistance.
+330 mbar Pressure
Positive-pressure capability supports pneumatic conveying, aeration, drying and other process-air duties.
Double-Stage Design
Two successive side channel stages enable greater vacuum and pressure differential than a comparable single-stage arrangement.
Oil-Free Air Path
No lubricating oil is required within the process-air chamber, helping provide clean airflow.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower construction to help manage operating sound.
Industrial Vacuum and Pressure Applications
The SV 700/2 5.5 kW is particularly useful where a comparatively high airflow is required together with moderate-to-high vacuum or positive-pressure differential.
› Vacuum lifting and handling
› Vacuum fixing and clamping
› Printing and paper machinery
› Packaging equipment
› Automated handling systems
› Pneumatic conveying
› Aeration systems
› Industrial drying
› Cooling and process airflow
› General mechanical engineering
SV 700/2 5.5 kW Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 700/2 5.5 kW blower supply for replacement machinery, maintenance requirements and new industrial installations.
For replacement requirements, provide clear photographs of the Becker blower and motor nameplates. This allows the exact motor configuration to be identified before quotation.
For new applications, provide the required airflow together with the normal working vacuum or positive pressure. Pipework bore, length, filters, valves and other restrictions can then be considered alongside the blower performance.
Although the SV 700/2 provides 375 m³/h nominal capacity at 50 Hz, correct selection should be based on the required airflow at the actual operating differential.
Accessories for Becker SV 700/2 Systems
Suitable filtration, correctly sized pipework and relief protection can help maintain the required airflow while keeping the blower within its intended differential range.
Inlet Filters
Correctly sized filtration protects the blower from contamination without introducing excessive suction-side restriction.
Vacuum Relief Valves
Vacuum relief can limit differential if inlet restriction rises beyond the intended operating condition.
Pressure Relief Valves
Pressure relief helps protect the blower where discharge blockage or restriction could increase differential excessively.
Installation Accessories
Flexible connectors, non-return valves and suitably sized pipework can form part of the complete installation.
Becker SV 700/2 5.5 kW Service, Repair and Spare Parts
The SV 700/2 uses non-contact compression, but blower reliability still depends on the motor, bearings, impeller condition and operating environment.
Blocked filtration, restricted pipework or process changes can increase differential and operating temperature. The connected system should therefore be checked alongside the blower whenever performance alters.
Vacuum Pumps UK can assist with Becker SV fault investigation, servicing and workshop repair.
Blower Service
Technical support for Becker blower maintenance, performance checks and operating problems.
Blower Repair
Workshop inspection and repair assessment for noisy, damaged or under-performing Becker SV units.
Spare Parts
Becker replacement filters and spare parts are available through our sister company VacAir Superstore.
Becker SV 700/2 5.5 kW Frequently Asked Questions
What airflow does the Becker SV 700/2 5.5 kW provide?
Nominal volume flow is 375 m³/h at 50 Hz and 435 m³/h at 60 Hz.
What is the maximum vacuum?
Maximum relative vacuum is -390 mbar at 50 Hz and -340 mbar at 60 Hz.
What is the maximum positive pressure?
Maximum relative pressure is +330 mbar at 50 Hz and +250 mbar at 60 Hz.
What does the /2 designation mean?
The /2 identifies the double-stage arrangement, where the process air passes through two side channel stages to develop greater differential.
How does the 5.5 kW version differ from the 7.5 kW SV 700/2?
Both provide the same nominal 375 m³/h capacity at 50 Hz, but the 7.5 kW version can operate against substantially greater positive-pressure differential and slightly greater maximum vacuum.
Is the SV 700/2 oil-free?
Yes. No lubricating oil is required in the process-air compression chamber.
Can Vacuum Pumps UK help identify an existing SV 700/2?
Yes. Send us clear photographs of the blower and motor nameplates and we can assist with identification, supply, servicing or repair.
