Becker SV 8.190/1 2kW Side Channel Blower
The Becker SV 8.190/1 is a single-stage side channel blower delivering 181 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -250 mbar and maximum positive pressure of +285 mbar.
Powered by a 2kW motor, this SV8 configuration combines moderate air volume with a useful level of vacuum and positive-pressure differential. It is well suited to industrial machinery where airflow has to be maintained through pipework, filtration, tooling or other components that create resistance within the system.
Vacuum and pressure are generated by regenerative side channel compression rather than sliding carbon vanes or an oil-sealed compression chamber. No lubricating oil is required within the process-air path, providing oil-free airflow for suitable industrial machine and process applications.

SV 8.190/1 Airflow with Useful Vacuum and Pressure Differential
The Becker SV 8.190/1 provides 181 m³/h nominal capacity from a 2kW motor. This places the blower in a useful range for individual production machines and local process systems that require more than unrestricted airflow and need the blower to operate against a meaningful vacuum or positive-pressure differential.
For suction-side applications, the SV 8.190/1 can develop maximum relative vacuum of -250 mbar. This allows it to serve vacuum handling, extraction and machine processes where air must continue to move as the suction level increases. On the discharge side, maximum relative positive pressure of +285 mbar provides capability for blowing, drying, process-air delivery and suitable conveying duties.
The combination of 181 m³/h airflow and the -250/+285 mbar differential range gives this configuration a different operating balance from lower-differential blowers. It can be particularly useful where the connecting pipework, filters, tooling or process creates resistance that the blower must overcome while maintaining sufficient airflow.
The regenerative operating principle uses a rotating impeller running within a side channel. Air entering the blower is accelerated repeatedly as it travels through the channel, with energy progressively transferred to the air before it reaches the discharge.
This method generates vacuum and pressure without rubbing carbon vanes. There is also no requirement for lubricating oil within the process-air chamber, providing an oil-free air path for suitable industrial applications.
Becker SV 8.190/1 Technical Specification
This 2kW SV 8.190/1 configuration provides 181 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -250 mbar and maximum relative positive pressure of +285 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 8.190/1 | Single Stage | 181 m³/h | -250 mbar | +285 mbar | 2kW |
The nominal 181 m³/h capacity and the maximum vacuum and pressure figures represent different operating points. They should not be interpreted as the blower delivering 181 m³/h while simultaneously operating at -250 mbar vacuum or +285 mbar pressure.
As resistance within the system increases, the blower develops greater differential and the available airflow changes. Selection should therefore be based on the volume of air required at the intended working vacuum or positive pressure.
Pipe diameter and length, bends, filters, silencers, valves, suction tooling and restrictions inside the machine can all contribute to the total resistance seen by the blower. Considering these factors is important when sizing a new installation or assessing a replacement.
SV 8.190/1 Performance Characteristics
181 m³/h Airflow
A useful nominal air volume for machine-mounted vacuum, blowing and local process-air applications.
-250 mbar Vacuum
Provides useful suction differential for handling, extraction and machine processes where vacuum must be maintained against system resistance.
+285 mbar Pressure
Positive-pressure capability for blowing, drying, process air and suitable light conveying applications.
Single-Stage Design
One regenerative side channel stage combines moderate airflow with useful vacuum and pressure capability.
2kW Motor
This SV 8.190/1 specification uses a 2kW electric motor at 50 Hz to provide its stated performance range.
Non-Contact, Oil-Free Air Path
Regenerative compression requires no rubbing carbon vanes and no lubricating oil within the process-air chamber.
Industrial Applications for the SV 8.190/1
The SV 8.190/1 can be used on either the vacuum or positive-pressure side of suitable machinery. Its combination of 181 m³/h nominal airflow and useful differential makes it particularly relevant where a compact blower has to overcome resistance within tooling, pipework or the process rather than simply circulate unrestricted air.
› Vacuum handling and lifting
› Packaging and production machinery
› Printing and paper equipment
› Industrial extraction
› Drying and cooling processes
› Blowing and process-air supply
› Light pneumatic conveying
› General industrial machinery
Application suitability should be determined from the required airflow at the actual working differential. A vacuum handling process operating at significant suction will have a different available airflow from an application running close to atmospheric pressure.
The condition of filtration and the size of connecting pipework are also important. Unnecessary restriction can increase the differential seen by the blower and move its operating point away from the intended duty.
Replacing a Becker SV 8.190/1
When an SV 8.190/1 is installed as part of production equipment, identifying the blower is only the first stage of selecting a replacement. The machine function and operating duty should also be considered, particularly where the blower works against a meaningful vacuum or positive-pressure differential.
Send Vacuum Pumps UK photographs of the complete blower together with clear images of the Becker identification plate and motor nameplate. Photographs showing the inlet, discharge and surrounding pipework can provide additional information about how the blower is being used.
Tell us whether the blower operates on vacuum or positive pressure and describe its function within the machine. If the normal operating vacuum, pressure or required airflow is known, include this information with the enquiry.
These details help us assess the installed specification and the actual process requirement rather than selecting from model designation or motor power alone.
Accessories and System Protection
The SV 8.190/1 should be installed with accessories appropriate to its operating environment and duty. Protecting the blower from contamination and excessive differential is important, but accessories should also be correctly sized so that they do not create unnecessary restriction.
Inlet Filtration
Suitable filtration helps protect the blower from airborne contamination while allowing sufficient airflow for the machine or process.
Relief Protection
Vacuum or pressure relief can help protect the blower if a filter blocks, a valve closes or the system becomes more restrictive than intended.
Silencers
Suitable inlet and discharge silencers can reduce transmitted air noise while maintaining an appropriate flow path through the system.
Pipework & Connections
Correct pipe diameter, flexible connections and appropriate fittings help minimise avoidable losses between the blower and application.
SV 8.190/1 Service, Repair and Spare Parts
The regenerative compression principle means there are no rubbing carbon vanes within the blower chamber. However, bearings, the electric motor and other mechanical components remain subject to wear and should not be overlooked when investigating changes in blower operation.
Increasing noise, vibration or operating temperature can indicate a mechanical problem requiring investigation. Reduced airflow, vacuum or pressure can also originate elsewhere in the installation, so filters, pipework, valves, leakage and process conditions should be checked alongside the blower itself.
Vacuum Pumps UK can inspect Becker side channel blowers in our workshop, investigate mechanical and performance problems and advise on servicing, repair or replacement following assessment.
