Becker SV 1100/1 11 kW Side Channel Blower
The Becker SV 1100/1 11 kW combines the high 1050 m³/h nominal airflow of the SV 1100/1 platform with substantially greater vacuum and positive-pressure capability.
At 50 Hz it is rated to -290 mbar relative vacuum and +260 mbar positive pressure. At 60 Hz, the corresponding 13.2 kW motor provides 1250 m³/h with maximum vacuum of -270 mbar and maximum pressure of +220 mbar.
This increased differential capability allows the blower to maintain useful airflow where pipework, filters, machinery or the process itself create considerably more resistance than a low-differential air-moving application.

High Airflow with Increased System Capability
The 11 kW SV 1100/1 provides a useful balance between the high airflow of the series and the ability to work against a substantial system differential. Nominal capacity remains 1050 m³/h at 50 Hz, but the larger motor allows operation to -290 mbar vacuum or +260 mbar pressure.
This is an important distinction when comparing SV 1100/1 configurations. The nominal capacity figure alone does not indicate how much airflow will remain once the blower is connected to a working system. As resistance increases, the relevant performance curve and motor configuration become increasingly important.
The 11 kW version can therefore be appropriate for installations involving longer pipe runs, greater filtration resistance, conveying duties or machinery where the process itself imposes a significant vacuum or pressure load.
Air is accelerated repeatedly through the side channel by the rotating impeller, creating the required differential without physical contact between the principal compression surfaces. The air chamber operates without lubricating oil.
For accurate selection, both volume flow and normal operating differential should be established. This is preferable to choosing the blower solely from either its nominal capacity or its maximum vacuum and pressure figures.
Becker SV 1100/1 11 kW Technical Specifications
The corresponding 50 Hz motor is rated at 11 kW and increases nominal capacity to 1050 m³/h. Maximum relative vacuum at 50 Hz is -290 mbar and maximum positive pressure is +260 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 1050 m³/h | -290 mbar | +260 mbar | 11 kW | 125 kg |
| 60 Hz | 1250 m³/h | -270 mbar | +220 mbar | 13.2 kW | 125 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 1100/1 11 kW
-290 mbar Vacuum
Provides substantially greater suction differential than the 7.5 kW version for more restrictive vacuum systems.
+260 mbar Pressure
Increased positive-pressure capability supports conveying, process-air and blowing duties with greater resistance.
High Volume Flow
Nominal capacity of 1050 m³/h at 50 Hz combines large-scale airflow with increased differential capability.
Oil-Free Compression
No oil is required within the compression chamber, helping provide clean process airflow.
Integrated Silencers
Inlet and discharge silencers form part of the standard blower construction to help control operating sound.
Non-Contact Air Path
Aerodynamic compression avoids rubbing compression elements within the process-air chamber.
High-Flow Applications with Greater Resistance
The 11 kW SV 1100/1 is particularly relevant where high airflow must be combined with enough differential to overcome restrictions within machinery, pipework or the process.

› Vacuum fixing systems
› Printing and paper machinery
› Packaging and processing equipment
› Automated material handling
› Pneumatic conveying

SV 1100/1 11 kW Supply and Duty Selection
Vacuum Pumps UK can assist with new Becker SV 1100/1 11 kW blower supply for replacement installations, machine builders and industrial projects.
When replacing an existing SV 1100/1, provide the complete blower and motor nameplates. The motor configuration is important because nominal airflow alone does not distinguish the different operating capabilities within this model family.
For new applications, provide the required flow together with the normal vacuum or positive-pressure differential. We can then consider whether the 11 kW version provides the appropriate balance of airflow and system capability.
Accessories for SV 1100/1 Vacuum and Pressure Systems
At higher airflow and differential, the pressure losses created by filters, valves and connecting pipework become an important part of the overall system. Correct accessory sizing helps avoid consuming useful blower performance unnecessarily.
Inlet Filters
Correct filter sizing protects the blower while limiting additional pressure loss on the suction side.
Vacuum Relief Valves
Vacuum relief can admit additional air if process restriction causes differential to exceed the intended operating duty.
Pressure Relief Valves
Relief protection helps protect the blower where discharge restriction could produce excessive positive pressure.
Installation Components
Pipework, flexible connectors and non-return valves should be selected with the high volume flow of the SV 1100/1 in mind.
Becker SV 1100/1 11 kW Service, Repair and Spare Parts
Although the SV side channel principle is non-contact, reliable performance still depends on the condition of the bearings, motor, impeller and complete connected system.
A change in process resistance can alter blower operation even when the blower itself has not developed a fault. Contaminated filtration, pipework blockage or changes to valves and equipment should therefore be considered when diagnosing reduced airflow or increased temperature.
Vacuum Pumps UK can assist where an SV 1100/1 develops noise, vibration, reduced output or another performance problem.

Blower Repair
Workshop inspection and repair assessment for noisy, damaged or under-performing side channel blowers.

Becker SV 1100/1 11 kW Frequently Asked Questions
What is the nominal capacity of the SV 1100/1 11 kW?
Nominal volume flow is 1050 m³/h at 50 Hz and 1250 m³/h at 60 Hz.
What maximum vacuum does it provide?
The maximum relative vacuum is -290 mbar at 50 Hz and -270 mbar at 60 Hz.
What is the maximum positive pressure?
The blower is rated to +260 mbar at 50 Hz and +220 mbar at 60 Hz.
How does the 11 kW version differ from the 7.5 kW SV 1100/1?
Both have the same 1050 m³/h nominal 50 Hz capacity, but the 11 kW version can operate against substantially greater vacuum and positive-pressure differential.
Does a larger motor automatically mean greater airflow?
No. The different SV 1100/1 motor configurations share the same nominal 50 Hz capacity. The larger motors primarily increase the permissible operating differential.
Why should system resistance be considered?
The blower must produce airflow against the combined resistance of pipework, filters, valves and the process. The actual operating point therefore matters more than free-air capacity alone.
Can Vacuum Pumps UK help with an existing SV 1100/1?
Yes. Send us the blower and motor nameplates and we can assist with identification, supply, service or workshop repair.
