Becker SV 200/2 1.1 kW Side Channel Blower
The Becker SV 200/2 1.1 kW is a double-stage side channel blower combining a nominal capacity of 90 m³/h with strong vacuum and positive-pressure performance for compact industrial air systems.
At 50 Hz the blower provides maximum relative vacuum of -330 mbar and maximum positive pressure of +300 mbar. At 60 Hz the corresponding 1.3 kW motor increases nominal capacity to 110 m³/h, with maximum vacuum of -300 mbar and maximum pressure of +260 mbar.
Its double-stage arrangement is designed for applications where overcoming system resistance is more important than achieving the higher free-air volume associated with a single-stage blower.

Double-Stage Performance for Higher System Resistance
The Becker SV 200/2 1.1 kW is designed around a different performance requirement from a high-volume single-stage blower. Its nominal 90 m³/h airflow is directed through two successive side channel stages, allowing the blower to develop considerably greater vacuum or positive-pressure differential.
At 50 Hz the SV 200/2 can produce up to -330 mbar relative vacuum, giving it strong suction capability for vacuum handling, holding and process applications. On pressure duty, maximum relative pressure is +300 mbar, allowing the same blower platform to be used in conveying, aeration and process-air systems.
The side channel principle uses a rapidly rotating impeller to repeatedly accelerate the gas around the annular channel. In the double-stage arrangement, airflow is redirected through the second side of the impeller so that additional pressure energy can be developed before discharge.
This process is non-contact and the compression chamber operates without lubricating oil. There are no rubbing vanes within the process-air path, making the SV 200/2 particularly useful where clean airflow and relatively low routine maintenance are desirable.
Correct selection should always consider the required flow at the actual operating vacuum or pressure. Pipe diameter, filters, valves and other restrictions can all influence the final duty point of a side channel blower installation.
Becker SV 200/2 1.1 kW Technical Specifications
The 50 Hz 1.1 kW configuration provides 90 m³/h nominal capacity. When operated at 60 Hz with the corresponding 1.3 kW motor rating, nominal flow increases to 110 m³/h.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 90 m³/h | -330 mbar | +300 mbar | 1.1 kW | 25.5 kg |
| 60 Hz | 110 m³/h | -300 mbar | +260 mbar | 1.3 kW | 25.5 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 200/2 1.1 kW
Double-Stage Design
Airflow is redirected through two side channel stages to develop increased vacuum and pressure differential.
Strong Vacuum Capability
Maximum relative vacuum of -330 mbar at 50 Hz gives the 1.1 kW version useful capability for restrictive suction duties.
+300 mbar Pressure
Positive-pressure operation supports industrial blowing, aeration, conveying and process-air applications.
Oil-Free Air Path
No lubricating oil is required within the compression chamber, helping provide clean process airflow.
Non-Contact Operation
The impeller operates without rubbing compression elements in the air chamber, reducing routine mechanical wear.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower construction to help manage operating noise.
Industrial Vacuum and Pressure Applications
The SV 200/2 1.1 kW is particularly suited to applications that require moderate airflow but appreciably greater differential than a simple low-pressure air-moving system.
› Vacuum lifting and handling
› Vacuum fixing and clamping
› Printing and paper machinery
› Packaging equipment
› Automated production machinery
› Pneumatic conveying
› Aeration systems
› Drying processes
› Cooling and process airflow
› General mechanical engineering
Becker SV 200/2 1.1 kW Supply and Selection
Vacuum Pumps UK can assist with Becker SV 200/2 1.1 kW supply for replacement requirements, machinery installations and new vacuum or positive-pressure applications.
If you are replacing an existing unit, send us clear photographs of both the Becker blower nameplate and the motor plate. This allows the exact model and motor configuration to be identified rather than relying on physical appearance alone.
For a new installation, provide the required airflow together with the normal operating vacuum or positive pressure. Information about pipe length, bore, filters and other significant restrictions can also help when assessing the required duty.
Because side channel blower performance changes as differential increases, selecting solely from the 90 m³/h nominal figure can give an incomplete picture of actual system performance.
Accessories for Becker SV 200/2 Installations
A correctly designed installation helps the blower operate at its intended duty point. Filtration, relief protection and suitable pipework should therefore be considered as part of the complete system.
Inlet Filters
Correctly sized filtration helps prevent contamination entering the blower without introducing unnecessary restriction.
Vacuum Relief Valves
Vacuum relief can protect the blower if suction restriction increases beyond the intended operating differential.
Pressure Relief Valves
Pressure relief helps protect against excessive differential caused by a restricted or obstructed discharge.
Installation Accessories
Flexible connectors, non-return valves and appropriately sized pipework can be incorporated into the blower system.
Becker SV 200/2 1.1 kW Service, Repair and Spare Parts
Although side channel compression is non-contact, the complete blower still relies on the motor, bearings, impeller condition and correct system operating point for reliable performance.
A blocked filter, restricted pipework or process change can increase differential and operating temperature. The surrounding system should therefore be checked as part of any investigation into reduced airflow, unusual noise or overheating.
Vacuum Pumps UK can assist with Becker SV blower fault investigation, servicing and workshop repair.
Blower Service
Technical support for Becker blower maintenance, performance checks and operating issues.
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 200/2 1.1 kW Frequently Asked Questions
What airflow does the Becker SV 200/2 1.1 kW provide?
Nominal volume flow is 90 m³/h at 50 Hz and 110 m³/h at 60 Hz.
What maximum vacuum can the SV 200/2 1.1 kW produce?
Maximum relative vacuum is -330 mbar at 50 Hz and -300 mbar at 60 Hz.
What is the maximum positive pressure?
Maximum relative positive pressure is +300 mbar at 50 Hz and +260 mbar at 60 Hz.
What does the /2 designation mean?
The /2 identifies the double-stage arrangement. Airflow is redirected through the second side channel stage to develop greater pressure differential.
Does the Becker SV 200/2 require oil in the compression chamber?
No. The side channel compression process operates without lubricating oil in the air chamber.
Should I select the blower from its 90 m³/h capacity alone?
No. The required flow at the actual operating vacuum or pressure should be considered because available airflow changes as system differential increases.
Can Vacuum Pumps UK identify an existing SV 200/2?
Yes. Send us clear photographs of the blower and motor nameplates and we can assist with identification, supply, service or repair.
