Becker SV 201/2 1.1 kW Side Channel Blower
The Becker SV 201/2 1.1 kW is a double-stage side channel blower providing 90 m³/h nominal airflow at 50 Hz with balanced vacuum and positive-pressure capability for industrial applications.
At 50 Hz it is rated to -280 mbar relative vacuum and +260 mbar positive pressure. At 60 Hz the corresponding 1.3 kW motor increases nominal flow to 110 m³/h, with maximum vacuum of -250 mbar and maximum positive pressure of +230 mbar.
The double-stage configuration is intended for applications where the blower must overcome more system resistance than a single-stage air mover while still providing a compact 90 m³/h nominal flow.

Balanced Double-Stage Vacuum and Pressure Performance
The 1.1 kW SV 201/2 provides a useful balance between airflow and pressure differential. Its nominal capacity of 90 m³/h is combined with a maximum relative vacuum of -280 mbar and positive pressure of +260 mbar at 50 Hz.
This performance profile makes the blower suitable for applications where the process requires more than low-pressure airflow but does not need the considerably greater differential available from the larger 1.5 kW SV 201/2 configuration.
In the double-stage arrangement, air gains energy through two successive side channel stages. This allows additional vacuum or discharge pressure to be developed without relying on contacting compression components.
The compression chamber is oil-free, so the process airflow is not exposed to lubricating oil. The impeller operates without rubbing contact in the air path, supporting relatively low routine maintenance requirements.
The nominal capacity should not be considered in isolation. Filters, bends, valves, pipework length and the connected process all introduce resistance, and the required flow at that actual differential is the important point when selecting a side channel blower.
Becker SV 201/2 1.1 kW Technical Specifications
At 50 Hz the corresponding motor rating is 1.1 kW and nominal capacity increases to 90 m³/h. Maximum relative vacuum is -280 mbar and maximum positive pressure is +260 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 90 m³/h | -280 mbar | +260 mbar | 1.1 kW | 25.5 kg |
| 60 Hz | 110 m³/h | -250 mbar | +230 mbar | 1.3 kW | 25.5 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 201/2 1.1 kW
Double-Stage Design
Two side channel stages allow greater differential to be produced from a relatively compact blower platform.
-280 mbar Vacuum
Useful suction capability suits vacuum handling, clamping and other systems with moderate inlet resistance.
+260 mbar Pressure
Positive-pressure capability supports conveying, aeration and process-air applications.
Oil-Free Air Path
No lubricating oil is required within the compression chamber, helping provide clean process airflow.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower construction to help manage operating noise.
Sealed Bearings
Sealed bearing construction eliminates routine bearing greasing and supports low maintenance operation.
Moderate-Flow Vacuum and Pressure Applications
The SV 201/2 1.1 kW is well suited to machinery and process systems where 90 m³/h nominal airflow is combined with a need to overcome a meaningful but not extreme system differential.
› Vacuum lifting and handling
› Vacuum clamping
› Printing and paper machinery
› Packaging equipment
› Automated machinery
› Pneumatic conveying
› Water Aeration systems
› Drying processes
› Cooling airflow
› General industrial engineering
SV 201/2 1.1 kW Supply and Application Support
Vacuum Pumps UK can assist with the supply of Becker SV 201/2 1.1 kW blowers for replacement machinery, planned maintenance requirements and new industrial systems.
For an existing installation, send us the complete blower and motor nameplate information. This helps identify the exact motor configuration and avoids relying on the SV 201/2 model designation alone.
For a new application, provide the required airflow together with the normal working vacuum or positive pressure. Pipework, filters, valves and process resistance can then be considered alongside the blower performance.
The 1.1 kW configuration is particularly relevant where the larger 1.5 kW differential capability is unnecessary for the actual system duty.
Accessories for Becker SV 201/2 Systems
Filtration, relief protection and pipework all influence the blower operating point. Correctly selected components help protect the blower while avoiding unnecessary additional system resistance.
Inlet Filters
Correctly sized filtration helps protect the blower from contamination while limiting pressure drop on the suction side.
Vacuum Relief Valves
Vacuum relief can admit additional air if inlet restriction causes differential to rise beyond the intended duty.
Pressure Relief Valves
Pressure relief helps protect against excessive discharge differential caused by a blockage or closed valve.
Installation Accessories
Flexible connectors, non-return valves and suitably sized pipework can form part of the complete installation.
Becker SV 201/2 1.1 kW Service, Repair and Spare Parts
The non-contact side channel principle reduces mechanical wear in the compression chamber, but blower performance still depends on the motor, bearings, impeller condition and the surrounding system.
Contaminated filters, restricted pipework or process changes can alter the operating differential and reduce available airflow. These system conditions should therefore be considered whenever a blower starts to operate hotter, noisier or less effectively.
Vacuum Pumps UK can assist with fault investigation, maintenance and workshop repair of Becker SV side channel blowers.
Blower Service
Technical support for Becker blower maintenance, performance checks and system-related operating issues.
Blower Repair
Workshop inspection and repair assessment for noisy, damaged or under-performing Becker side channel blowers.
Spare Parts
Replacement filters and Becker spare parts are available through our sister company VacAir Superstore.
Becker SV 201/2 1.1 kW Frequently Asked Questions
What airflow does the Becker SV 201/2 1.1 kW provide?
Nominal volume flow is 90 m³/h at 50 Hz and 110 m³/h at 60 Hz.
What is the maximum vacuum?
Maximum relative vacuum is -280 mbar at 50 Hz and -250 mbar at 60 Hz.
What is the maximum positive pressure?
The blower is rated to +260 mbar at 50 Hz and +230 mbar at 60 Hz.
Is the SV 201/2 a double-stage blower?
Yes. The /2 configuration uses two side channel stages to develop greater vacuum or pressure differential.
How does the 1.1 kW version differ from the 1.5 kW model?
Both provide the same nominal 90 m³/h capacity at 50 Hz, but the 1.5 kW version can operate against substantially greater vacuum and positive-pressure differential.
Does the blower require oil in the air chamber?
No. The compression chamber operates without lubricating oil.
Can Vacuum Pumps UK help identify my existing SV 201/2?
Yes. Send us clear photographs of the blower and motor nameplates and we can assist with identification, supply, servicing or repair.
