Becker SV 8.190/2 2kW Side Channel Blower
The Becker SV 8.190/2 is a two-stage side channel blower delivering 98 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -375 mbar and maximum positive pressure of +430 mbar.
Driven by a 2kW motor, this SV8 two-stage configuration is particularly relevant where the required air volume is moderate but the blower must work against a comparatively high vacuum or positive-pressure differential. This makes operating resistance and the actual duty point especially important when selecting or replacing the blower.
Regenerative side channel compression develops vacuum and pressure without rubbing carbon vanes and without lubricating oil within the process-air chamber. The result is an oil-free air path for suitable vacuum handling, conveying, packaging and industrial process-air applications.

Higher Differential from the Two-Stage SV 8.190/2
The Becker SV 8.190/2 provides 98 m³/h nominal capacity from a 2kW motor, but its defining characteristic is the level of vacuum and positive-pressure differential available from its two-stage regenerative design.
On the suction side, maximum relative vacuum of -375 mbar provides strong vacuum capability for machinery where the blower must draw air through tooling, pipework, filtration or other restrictions. On the pressure side, maximum relative pressure of +430 mbar allows the blower to deliver air into systems presenting significant back pressure.
The relationship between airflow and differential is therefore particularly important on this model. Its 98 m³/h nominal capacity should not be viewed in isolation; for many applications, the reason for selecting a two-stage SV 8.190/2 will be its ability to develop considerably greater differential than a blower intended mainly for higher free-air volume.
The two-stage regenerative arrangement transfers energy to the air progressively. As the impellers rotate, air is repeatedly accelerated through the side channels, building the required pressure difference before leaving the blower.
There are no sliding carbon vanes involved in the compression process and no lubricating oil is required within the process-air chamber. This provides oil-free airflow for suitable industrial processes while retaining the vacuum and pressure capability of the two-stage design.
Becker SV 8.190/2 Technical Specification
The 2kW SV 8.190/2 provides 98 m³/h nominal capacity at 50 Hz. Maximum relative vacuum is -375 mbar and maximum relative positive pressure is +430 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 8.190/2 | Two Stage | 98 m³/h | -375 mbar | +430 mbar | 2kW |
The nominal 98 m³/h capacity and maximum differential values are different operating points. They do not mean that the blower provides 98 m³/h while simultaneously operating at -375 mbar vacuum or +430 mbar positive pressure.
As resistance in the connected system increases, the vacuum or positive-pressure differential rises and the available airflow changes along the blower’s performance characteristic. The correct blower therefore needs to be selected for the required airflow at the actual operating differential.
This becomes especially important with two-stage blowers because differential capability is often a primary reason for their selection. Pipework, filtration, silencers, valves, tooling and restrictions within the machine can all influence the final operating point.
SV 8.190/2 Performance Characteristics
98 m³/h Airflow
Moderate nominal air volume for industrial machine and process duties where higher differential is required.
-375 mbar Vacuum
Strong suction capability for machine vacuum, handling and processes operating against substantial inlet-side resistance.
+430 mbar Pressure
High positive-pressure differential for blowing, conveying and process-air duties with appreciable system resistance.
Two-Stage Configuration
Successive regenerative stages allow greater total vacuum and pressure differential than a comparable single-stage arrangement.
2kW Motor
The 50 Hz SV 8.190/2 configuration covered here uses a 2kW electric motor to provide its specified performance.
Oil-Free Air Path
Regenerative compression operates without rubbing carbon vanes and without lubricating oil within the process-air chamber.
Applications for the Becker SV 8.190/2
The SV 8.190/2 is suited to industrial duties where the required airflow is moderate but the machine or process creates significant resistance. Its two-stage arrangement can provide either vacuum or positive-pressure operation where the required duty falls within the blower’s performance range.
› Vacuum handling and holding systems
› Packaging and production machinery
› Printing and paper equipment
› Machine vacuum applications
› Pneumatic conveying duties
› Drying and process-air systems
› Air delivery through restrictive equipment
› Aeration and agitation
The actual operating point remains critical. A system requiring approximately 98 m³/h at low differential represents a very different duty from an application working close to -375 mbar vacuum or +430 mbar positive pressure.
Pipe diameter, pipe length, bends, filters, silencers, valves and restrictions within the machine all contribute to the resistance seen by the blower. These factors should be considered when establishing suitability for a new installation or replacement.
Replacing an Existing Becker SV 8.190/2
When replacing an SV 8.190/2, matching nominal airflow alone is not sufficient. The two-stage blower may have been selected specifically because the machine requires its higher 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. Images showing the inlet, discharge, filtration and surrounding pipework can also help establish how the blower is configured within the system.
Tell us whether the blower is used on vacuum or positive pressure and describe its function within the machine. Where available, include the normal operating vacuum or pressure, required airflow and details of any filtration or process restrictions.
This information allows the replacement to be assessed against the actual operating requirement rather than assuming that another 2kW blower or a unit with similar free-air capacity will provide equivalent performance.
Accessories and System Protection
The SV 8.190/2 is capable of developing substantial differential, so filtration, relief protection and correctly sized pipework are important parts of the complete installation. Accessories should protect the blower without introducing unnecessary resistance.
Inlet Filtration
Suitable filtration helps prevent airborne contamination entering the blower while providing sufficient flow area for the required duty.
Relief Protection
Vacuum or pressure relief can help limit excessive differential if a filter blocks, a valve closes or the process becomes more restrictive.
Silencers
Appropriately selected silencers can reduce transmitted air noise while avoiding unnecessary additional restriction in the airflow path.
Pipework & Connections
Suitable pipe diameter, flexible connections and correctly selected fittings help control pressure losses between the blower and process.
SV 8.190/2 Service, Repair and Spare Parts
The regenerative operating principle avoids rubbing carbon vanes within the compression chamber, but the SV 8.190/2 still contains bearings, an electric motor and other mechanical components that can wear during industrial service.
Changes in noise, vibration or operating temperature should be investigated. A reduction in vacuum, pressure or airflow should also prompt checks of the surrounding system because blocked filtration, leakage, restricted pipework or altered process conditions can change blower performance.
With a two-stage blower, system resistance deserves particular attention. A relatively small change to filtration or pipework can alter the differential against which the blower is operating and consequently change the available airflow.

What maximum vacuum does the SV 8.190/2 produce?
The listed maximum relative vacuum is -375 mbar.
What is the maximum positive pressure of the SV 8.190/2?
The listed maximum relative positive pressure is +430 mbar.
What motor power does this SV 8.190/2 use?
The configuration covered on this page uses a 2kW electric motor at 50 Hz.
Is the Becker SV 8.190/2 a two-stage blower?
Yes. It uses a two-stage regenerative side channel arrangement to develop higher vacuum and positive-pressure differential.
Why is the airflow lower than a single-stage blower of similar size?
The two-stage arrangement places greater emphasis on developing vacuum or pressure differential rather than maximising nominal free-air volume. The correct comparison therefore depends on the required airflow at the actual operating differential.
Can the SV 8.190/2 operate on vacuum and positive pressure?
Yes. It can be used on either the suction or discharge side where the required duty falls within its performance range.
Does the SV 8.190/2 use carbon vanes or lubricating oil in the process-air chamber?
No. It uses regenerative side channel compression rather than rubbing carbon vanes, and lubricating oil is not required within the process-air chamber.
Does 98 m³/h mean the blower delivers that airflow at -375 mbar or +430 mbar?
No. Nominal capacity and maximum differential represent different operating points. Available airflow changes as the blower operates against increasing vacuum or positive-pressure differential.
Can Vacuum Pumps UK help replace an existing SV 8.190/2?
Yes. Send us photographs of the complete blower, Becker identification plate and motor nameplate together with information about the application and any known operating vacuum, pressure or airflow.
