Becker SV 1100/2 7.5 kW Side Channel Blower
The Becker SV 1100/2 7.5 kW is a high-capacity double-stage side channel blower providing 520 m³/h nominal volume flow for industrial vacuum and positive-pressure applications.
At 50 Hz it provides maximum relative vacuum of -350 mbar and maximum positive pressure of +260 mbar. At 60 Hz the corresponding 9 kW motor increases nominal capacity to 610 m³/h, with maximum vacuum of -260 mbar and maximum positive pressure of +180 mbar.
This configuration is particularly suited where high process-air volume is more important than the very high differential available from the larger 11 kW SV 1100/2.

High-Volume Double-Stage Process Air
The Becker SV 1100/2 7.5 kW combines 520 m³/h nominal airflow with double-stage side channel compression. It is aimed at industrial systems where a large volume of air must be moved while still overcoming meaningful suction or discharge resistance.
At 50 Hz, maximum relative vacuum is -350 mbar and maximum positive pressure is +260 mbar. The performance profile therefore differs significantly from the higher-powered 11 kW configuration: the 7.5 kW model retains the same nominal airflow but is intended for less severe differential requirements.
The /2 design redirects the process air through a second side channel stage. Energy is transferred from the rotating impeller into the air without rubbing compression elements, allowing useful pressure differential to be developed while retaining the characteristic high-flow operation of a side channel blower.
Compression is oil-free and non-contact. No lubricating oil is required within the process-air chamber, making the SV 1100/2 suitable for applications where clean airflow is important.
The actual installed airflow depends on the working differential. Pipework, filters, valves and process restrictions all influence the operating point, so blower selection should be based on required flow at the normal system vacuum or pressure rather than nominal capacity alone.
Becker SV 1100/2 7.5 kW Technical Specifications
At 50 Hz the corresponding motor rating is 7.5 kW and nominal volume flow is 520 m³/h.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 520 m³/h | -350 mbar | +260 mbar | 7.5 kW | 118 kg |
| 60 Hz | 610 m³/h | -260 mbar | +180 mbar | 9 kW | 118 kg |
Vacuum and pressure figures are relative. Weight is 118 kg including motor.
Key Features of the SV 1100/2 7.5 kW
520 m³/h Capacity
High nominal airflow makes this configuration suitable for larger industrial process-air systems.
-350 mbar Vacuum
Provides useful suction differential while retaining the high-volume characteristics of the SV 1100 platform.
+260 mbar Pressure
Positive-pressure capability suits high-volume conveying, aeration, drying and process-air duties.
Double-Stage Design
Process air passes through two successive side channel stages to develop increased differential.
Oil-Free Compression
No lubricating oil is required within the process-air chamber, helping provide clean airflow.
Integrated Silencers
Becker incorporates inlet and discharge silencers into the blower construction.
High-Volume Industrial Applications
The SV 1100/2 7.5 kW is suited to larger installations requiring substantial airflow together with useful vacuum or positive-pressure differential.
› Vacuum lifting and handling
› Large vacuum holding systems
› Printing and paper machinery
› Packaging equipment
› Automated production machinery
› Pneumatic conveying
› Water Aeration systems
› Industrial drying
› Cooling and process airflow
› General mechanical engineering
SV 1100/2 7.5 kW Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 1100/2 7.5 kW supply for replacement requirements and new industrial vacuum or pressure installations.
For replacement equipment, send us clear photographs of the blower and motor nameplates. This helps confirm the exact motor configuration before quotation.
For new applications, provide the required airflow together with the normal working vacuum or positive pressure. Pipework bore and length, filtration, valves and other significant restrictions should also be considered.
The 7.5 kW and 11 kW SV 1100/2 configurations share the same nominal 520 m³/h airflow at 50 Hz but have very different maximum differential capabilities, making correct duty-point selection important.
Accessories for Becker SV 1100/2 Installations
Large-volume blower systems require careful attention to filtration, pipework sizing and relief protection to avoid unnecessary restriction and maintain the required operating point.
Inlet Filters
Correctly sized filtration helps protect the blower while minimising unwanted suction-side pressure loss.
Vacuum Relief Valves
Vacuum relief can limit excessive differential if inlet or process restriction increases unexpectedly.
Pressure Relief Valves
Pressure relief can protect the blower if discharge restriction pushes the system beyond its intended operating condition.
Installation Accessories
Flexible connectors, non-return valves and suitably sized pipework can form part of the complete installation.
Becker SV 1100/2 Service, Repair and Spare Parts
The SV 1100/2 uses non-contact compression, but reliable operation still depends on the motor, bearings, impeller and the conditions created by the connected system.
Dirty filters, restrictive pipework, closed valves or process changes can increase differential and blower temperature. These external factors should be checked alongside the blower whenever performance changes.
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 1100/2 7.5 kW Frequently Asked Questions
What airflow does the Becker SV 1100/2 7.5 kW provide?
Nominal volume flow is 520 m³/h at 50 Hz and 610 m³/h at 60 Hz.
What is the maximum vacuum?
Maximum relative vacuum is -350 mbar at 50 Hz and -260 mbar at 60 Hz.
What positive pressure can it provide?
Maximum relative pressure is +260 mbar at 50 Hz and +180 mbar at 60 Hz.
What does the /2 designation mean?
The /2 identifies the double-stage arrangement, where process air passes through two side channel stages to develop increased differential.
Is the compression process oil-free?
Yes. No lubricating oil is required within the process-air compression chamber.
How does this differ from the 11 kW SV 1100/2?
Both have the same nominal 520 m³/h capacity at 50 Hz, but the 11 kW version provides substantially greater maximum vacuum and positive-pressure differential.
Can Vacuum Pumps UK help identify an existing SV 1100/2?
Yes. Send us clear photographs of the blower and motor nameplates and we can assist with identification, supply, servicing or repair.
